Water Pumps for Brisbane, Gold Coast & South East Queensland

Water pumps are used to move water, increase pressure or automatically manage water supply around homes, rainwater tanks, gardens, sheds and larger properties. The right pump depends on where the water comes from, where it needs to go, how much flow is required and the pressure needed when it gets there.

JR Gas & Water supplies and installs household water pumps throughout Greater Brisbane, the Gold Coast, Logan, Ipswich, Redlands, Moreton Bay, Scenic Rim and surrounding South East Queensland areas.

Our range includes mains water pressure booster pumps, rainwater tank pumps, rain-to-mains systems, surface pressure pumps, submersible pumps, smart variable-speed pumps, garden pumps and larger whole-house water supply systems.

Choosing a water pump from motor wattage or maximum flow alone can produce a poor result. Pump selection should consider the required duty point, pipework, elevation, suction conditions, number of outlets, water source, controllers, filtration and how the property actually uses water.

JR Installer Verdict: Do not start by asking which pump is biggest. Start by asking what flow and pressure the property needs at the same time. The best pump is normally the smallest correctly sized pump that comfortably meets the real duty.

What Does a Water Pump Do?

A water pump converts electrical energy into hydraulic energy so water can be moved through pipework at useful flow and pressure.

Residential pumps are used for several very different jobs. A pump that is excellent for garden watering may be unsuitable for boosting mains water pressure. A rain-to-mains system performs a different job from a basic tank pump, and a submersible pump behaves differently from a surface-mounted pump.

Moves Water

Transfers water from a tank, bore, storage vessel or other suitable source to where it is needed.

Creates Pressure

Provides the pressure required to operate taps, showers, toilets, appliances or irrigation downstream.

Manages Demand

Controllers or variable-speed systems can start, stop or adjust the pump as water demand changes.

Choose a Water Pump by What You Need It to Do

The application should normally be selected before the brand or model. Different pump types solve different water-supply problems.

Mains Water Pressure Boosting

For suitable properties where incoming pressure or available pressure at fixtures is inadequate and a compliant booster arrangement is appropriate. Smart variable-speed pumps are particularly useful where stable household pressure is the goal.

Rainwater Tank Supply

Moves stored rainwater from a tank to garden taps, toilets, laundries, irrigation or other connected fixtures.

Rainwater tank plumbing →

Rain-to-Mains Systems

Prioritise rainwater when available and automatically use mains water backup when the rainwater supply is unavailable, depending on the system design.

Whole-House Water Supply

For properties where a pump supplies a large portion or all of the household water demand and needs to maintain useful flow across multiple outlets.

Garden & Irrigation

Pumps for garden taps, hoses and irrigation where the required flow and pressure are determined by the watering system rather than bathroom demand.

Pump Replacement

Replacement of failed, noisy, leaking, poorly cycling or undersized pumps, including like-for-like replacement and upgrades where the existing setup no longer suits the property.

JR Installer Verdict: The application comes first. A rainwater harvesting pump, smart mains booster and basic garden pressure pump may all move water, but they should not be treated as interchangeable products.

Types of Household Water Pumps

Pressure Pumps

Automatically provide water pressure when an outlet opens. Common for tank water, gardens and household supply.

Booster Pumps

Designed to increase pressure within a suitable existing supply system where boosting is required and permitted.

Variable-Speed Pumps

Adjust motor speed as water demand changes, helping maintain a steadier target pressure across varying flow conditions.

Jet Pumps

Surface-mounted pumps commonly used for tank supply, suction applications, garden watering and traditional household pressure systems.

Multistage Pumps

Use multiple impeller stages to develop pressure efficiently and are commonly used where smoother household pressure or higher head is required.

Submersible Pumps

Operate inside the water source, such as a rainwater tank, reducing external pump clutter and changing the suction conditions compared with a surface pump.

Compare Water Pump Types

Pump Type Main Use Main Advantage Main Consideration
Traditional Pressure Pump Tank, garden, household supply Simple and practical Correct controller and sizing are important
Variable-Speed Pump Premium household pressure Stable pressure across changing demand Higher initial cost and more sophisticated controls
Mains Booster Suitable low-pressure mains applications Can improve pressure at household fixtures Installation must suit the water supply and plumbing conditions
Rain-to-Mains Pump Rainwater harvesting Automatic rainwater priority with backup capability Controller and mains integration are part of the system
Surface Pump Tank, garden, household supply Easy physical access for service Suction conditions matter
Submersible Pump Rainwater tank supply Installed inside the tank and often quieter externally Removal from the tank may be required for servicing

Water Pump Flow vs Pressure – What Is the Difference?

Flow and pressure are related but they are not the same measurement. Both need to be considered when selecting a pump.

Flow – Litres per Minute

Flow describes how much water is moving through the system. A property using several outlets at the same time needs more total flow than a single garden tap.

Pressure – kPa or Head

Pressure describes the force available to move water through the plumbing and operate fixtures. Pump performance is often represented as metres of head as well as pressure.

JR Installer Verdict: A pump's maximum flow is normally measured at very low resistance, while its maximum pressure occurs at little or no flow. Neither number tells you the real operating performance by itself. The useful number is what the pump can deliver at the property's required flow and head.

What Is a Water Pump Duty Point?

The duty point is the operating combination of flow and pressure or head that the pump needs to provide in the actual system.

A pump curve shows how much flow a pump can produce at different head conditions. As the required head increases, available flow normally decreases. The pump should therefore be selected from the part of its performance curve that matches the site's real operating requirement rather than from its maximum advertised numbers.

Duty Point Can Be Affected By:

  • Number of outlets likely to operate together.
  • Desired pressure at those outlets.
  • Vertical elevation.
  • Pipe diameter.
  • Pipe length.
  • Valves and fittings.
  • Water filters.
  • Backflow devices.
  • Suction conditions.
  • Irrigation equipment.
  • Existing plumbing restrictions.
JR Installer Verdict: Pump curves matter more than the biggest number printed on the box. Compare the pump at the pressure and flow the property will actually use.

What Does Pump Head Mean?

Pump head expresses the energy a pump can give the water and is commonly stated in metres. It is useful because it combines pressure requirements and elevation into the way pump performance is assessed.

As a useful conversion, approximately 10 metres of water head corresponds to about 98 kPa of pressure. Real pump sizing also needs to account for friction loss through pipework, valves, fittings and filtration.

Static Head

The vertical height difference the system needs to overcome.

Friction Loss

Pressure lost as water travels through pipework, bends, valves, filters and other restrictions.

Required Outlet Pressure

Pressure that still needs to remain at the tap, shower, irrigation system or other point of use.

What Size Water Pump Do I Need?

Water pump sizing should be based on the real duty rather than bedrooms, motor wattage or tank capacity alone.

Application Main Sizing Question What to Check
Garden tap How much flow and pressure does the hose or irrigation need? Pipe length, elevation and watering equipment
Small tank supply How many outlets can run together? Suction, pipe size and controller
Whole-house tank supply What is realistic peak household demand? Bathrooms, fixtures, elevation and filtration
Mains boosting What pressure is available and what improvement is required? Incoming supply, plumbing restrictions and compliance
Rain-to-mains Which fixtures use rainwater and when is backup required? Tank, mains connection, controller and pump capacity
Irrigation What does the irrigation zone require at operating pressure? Sprinklers, zone flow, pipework and elevation
JR Installer Verdict: Size down intelligently. An oversized pump can create cycling, noise, excessive pressure and unnecessary cost. Choose enough pump to meet peak realistic demand with sensible reserve rather than simply buying the largest model.

Mains Water Pressure Booster Pumps

A booster pump can be considered on suitable properties where available mains-water pressure does not provide the required performance at household fixtures.

Before choosing a pump, the existing supply should be assessed. Low pressure at one fixture can have a very different cause from low pressure across the entire property.

Before Boosting Mains Pressure, Check:

  • Incoming static pressure.
  • Pressure while water is flowing.
  • Water meter and incoming pipe size.
  • Pressure-limiting or reducing valves.
  • Blocked strainers or filters.
  • Old or restrictive pipework.
  • Whether the problem affects one fixture or the whole property.
  • Required peak household flow.
  • The permitted plumbing arrangement for the property.
JR Installer Verdict: A pump should not be used to disguise another restriction. Confirm the cause of poor pressure before installing a booster.

Rainwater Tank Pumps

A rainwater pump takes stored tank water and supplies it at useful pressure to the fixtures connected to the rainwater system. This may include garden taps, irrigation, toilets, laundry or broader household use depending on the property.

The pump is only one part of the system. Tank outlets, suction pipework, filters, controllers, mains backup, check valves and the plumbing to the home can all affect performance.

Garden Tank Pump

Simple pressure supply for hoses, garden taps and suitable irrigation.

Tank-to-House Pump

Higher-duty pressure supply for toilets, laundry, taps or whole-house use where configured that way.

Rain-to-Mains System

Automated arrangement designed to prioritise tank water while providing mains backup when required.

View rainwater tank plumbing & pump connections →

How Does a Rain-to-Mains Pump System Work?

A rain-to-mains system is designed to use collected rainwater when available and provide an alternative mains supply when the tank cannot meet demand. The exact switching method varies between systems.

1. Rainwater Available

The system supplies designated fixtures from stored rainwater.

2. Pump Creates Pressure

The pump provides the pressure needed to deliver tank water to the property.

3. Tank Supply Unavailable

The controller identifies the condition according to the system design.

4. Mains Backup

The system provides mains-water backup through its approved switching arrangement.

JR Installer Verdict: A RainBank-style setup is more than a pump beside a tank. The pump, controller, tank plumbing and mains backup arrangement form one complete rainwater harvesting system.

Surface vs Submersible Water Pumps

Feature Surface Pump Submersible Pump
Position Outside the tank / water source Inside the water
Suction Needs suitable suction conditions Water is already at the pump inlet
External noise Pump remains externally audible Often less pump noise outside the tank
Service access Direct physical access Pump may need to be removed from tank
Weather exposure External installation needs suitable protection Pump itself operates submerged
Typical use Tank, garden and household pressure Rainwater tanks and in-tank supply

Why Suction Conditions Matter for Surface Pumps

A surface pump cannot be selected only from its discharge performance. The water also has to reach the pump inlet correctly.

Suction Performance Can Be Affected By:

  • Vertical lift from water level to pump.
  • Distance between tank and pump.
  • Suction pipe diameter.
  • Excessive bends or restrictions.
  • Air leaks on the suction side.
  • Blocked strainers or tank outlets.
  • Low tank water level.
  • Incorrect non-return valves.
  • Poor priming.
  • Water temperature and operating conditions.
JR Installer Verdict: A surface pump can have excellent pressure capability and still perform badly if the suction side is undersized, leaking air or asking the pump to lift water under unsuitable conditions.

What Is Pump Cavitation?

Cavitation can occur when pressure at the pump inlet falls too low and vapour bubbles form and collapse within the pump. It can cause noise, vibration, reduced performance and damage over time.

Poor suction design, excessive suction lift, restricted pipework and insufficient available inlet pressure can contribute to cavitation conditions.

JR Installer Verdict: If a pump sounds like it is moving gravel, do not assume the pump itself is the only problem. Check the suction conditions and water supply to the pump.

Variable-Speed vs Fixed-Speed Water Pumps

Feature Variable-Speed Pump Traditional Fixed-Speed Pump
Motor operation Speed changes with demand Runs at its fixed operating speed when activated
Pressure control Can maintain a more consistent target pressure Pressure varies through controller operating range
Low-flow demand Can reduce speed where system design permits Starts and runs at normal speed
Controls Integrated electronics / inverter common Simpler pressure or flow controller common
Purchase cost Generally higher Generally lower
Best suited to Premium whole-house pressure performance Simple tank, garden and household applications
JR Installer Verdict: Variable speed is most valuable where consistent pressure across changing household demand matters. It is not automatically necessary for a single garden tap or straightforward pump replacement.

Water Pump Controllers, Pressure Switches & Pressure Tanks

The way a pump starts and stops is just as important as the pump itself. Different systems use electronic controllers, pressure switches, integrated variable-speed controls or pressure tanks to manage operation.

Electronic Pump Controller

Can automatically start a pump when demand is detected and stop it after flow ends, depending on the controller design.

Pressure Switch

Starts and stops the pump between defined pressure settings, commonly in systems incorporating a pressure tank.

Pressure Tank

Stores a small volume of pressurised water and can reduce unnecessary pump starts in a correctly configured pressure system.

Why Does a Water Pump Keep Turning On & Off?

Rapid or repeated pump cycling can be a sign that the pump system is not operating correctly.

Possible Causes Can Include:

  • A leaking tap or toilet.
  • A plumbing leak downstream.
  • Failed or incorrectly charged pressure tank.
  • Controller fault.
  • Non-return valve problems.
  • Loss of pressure within the system.
  • Pump oversizing for very small demand.
  • Incorrect control settings.
JR Installer Verdict: Do not automatically replace a cycling pump. The pump may simply be reacting to a leak, failed valve, controller problem or pressure tank fault elsewhere in the system.

Why Pipe Size Matters

A large pump cannot force unlimited water through undersized or restrictive pipework without consequences. As flow increases through a small pipe, friction losses increase and useful pressure can fall.

Pump sizing should therefore consider both the equipment and the plumbing connected to it.

Suction Pipework

Restrictive suction pipework can reduce pump inlet conditions and contribute to poor performance.

Discharge Pipework

Long or undersized downstream plumbing can consume pressure before the water reaches the fixtures.

JR Installer Verdict: Upgrading the pump while leaving severely restrictive pipework can produce far less improvement than the customer expects.

How Elevation Affects Water Pump Performance

A pump supplying a fixture substantially above the pump has to overcome that vertical elevation before useful pressure remains at the outlet.

This becomes particularly important on sloping blocks, acreage properties, multi-storey homes, tank-to-shed systems and long rural water runs.

JR Installer Verdict: Distance matters, but elevation can matter even more. A pump moving water 100 metres across relatively level ground faces a different duty from one pushing water a much shorter distance significantly uphill.

Water Pumps & Water Filtration

Water filters create resistance to flow. Where filtration is installed on a pump-fed system, the pump and filter should be considered together rather than selected independently.

A loaded cartridge can also create more pressure loss than a new cartridge, which means the system should retain acceptable performance as filters move through their normal service life.

Pump Before Filtration

Common on rainwater systems where the pump creates the pressure that drives water through the treatment equipment.

Filter Pressure Loss

Housing size, cartridge type, flow and cartridge condition all influence the pressure available after the filter.

Compare water filtration systems →

JR Installer Verdict: Do not increase pump pressure simply to compensate for an undersized or blocked filter. The pump and filtration system both need to suit the required flow.

What Makes a Water Pump Quiet?

Pump noise depends on more than the manufacturer's sound figure. Pump type, motor speed, mounting, pipework, location and the building structure can all affect how much noise is noticed.

Pump Technology

Variable-speed and integrated premium pumps can offer smoother and quieter operation in suitable household applications.

Installation Surface

Rigid mounting to a resonant structure can transmit vibration into walls, floors and surrounding building components.

Location

A pump beside a bedroom window has a very different noise impact from one in a suitable service area away from occupied rooms.

JR Installer Verdict: The quietest pump on paper can still be annoying if it is mounted badly or installed in the wrong position. Pump selection and placement both matter.

Water Pump Installation Brisbane & Gold Coast

JR Gas & Water supplies and installs water pumps throughout Brisbane, the Gold Coast and surrounding South East Queensland areas. Installation depends on whether the job is a straightforward replacement, mains booster, rainwater system, new tank connection or complete household pressure upgrade.

1. Identify the Water Source

Confirm whether the pump is supplied from mains water, a rainwater tank or another suitable water source.

2. Determine the Required Duty

Assess required flow, pressure, outlets, elevation, pipework and how the property will use water.

3. Select the Pump

Choose the pump type and model around the actual system requirement rather than peak catalogue numbers.

4. Check the Installation Position

Review access, weather protection, suction conditions, drainage, noise, ventilation where relevant and future servicing.

5. Install & Connect

Connect the required pump, controls, valves and associated plumbing according to the selected system.

6. Test & Commission

Check pump operation, pressure, flow, controller behaviour and the connected fixtures before completion.

Water Pump Power & Electrical Requirements

Residential water pumps commonly require a suitable electrical supply. Requirements vary between models, and the installation should follow the electrical requirements of the selected pump and site.

Some pumps use conventional plug-and-lead arrangements while others may form part of a more involved installation. Smart pumps can also include electronic controllers, displays, variable-speed drives or connectivity features.

JR Installer Verdict: Choose the pump first from the hydraulic requirement, then confirm that the site can provide the electrical supply and installation conditions that model requires.

Water Pump Protection & Installation Position

Where a surface-mounted pump is installed matters. Equipment should remain accessible for service while also being protected according to the manufacturer's installation requirements.

Consider:

  • Weather exposure.
  • Flooding or surface water.
  • Ventilation where required.
  • Distance from bedrooms and living areas.
  • Stable mounting surface.
  • Pipe strain and vibration.
  • Electrical access.
  • Tank and suction location.
  • Service clearance.
  • Future pump replacement access.

Common Water Pump Problems

Pump Will Not Start

Possible causes can include power, controller, motor, water supply or system faults and should be properly diagnosed.

Pump Runs but No Water

Can relate to priming, suction leaks, low tank level, blocked inlet or other water-supply problems.

Pump Keeps Cycling

Can result from leaks, controller issues, non-return valves, pressure tanks or incorrect system configuration.

Low Water Pressure

Can be caused by pump sizing, pipe restrictions, blocked filters, suction problems or another issue outside the pump itself.

Pump Is Noisy

Noise can relate to mounting, cavitation, worn components, operating speed, pipe vibration or installation location.

Pump Leaks

Water leakage should be inspected to determine whether the source is the pump, connections, seals or surrounding plumbing.

JR Installer Verdict: A faulty water system does not always mean a faulty pump. Diagnose the water source, plumbing and controls before replacing equipment unnecessarily.

Should I Repair or Replace My Water Pump?

The best option depends on the pump's age, fault, parts availability, condition and whether the existing model is correctly sized for the property.

Repair Can Make Sense When

  • The pump itself remains in good condition.
  • The fault is isolated to a replaceable component.
  • Parts remain practical to source.
  • The pump is correctly sized.
  • Repair cost remains sensible.

Replacement Can Make Sense When

  • The pump has major motor or hydraulic failure.
  • Repeated faults are occurring.
  • The existing pump is badly sized.
  • Parts are unavailable or uneconomical.
  • A different pump type better suits the property.

How Much Does Water Pump Installation Cost?

Water pump cost varies because a simple pressure-pump replacement and a new rain-to-mains or premium variable-speed system require different equipment and installation work.

JR Gas & Water displays current pump products and installed pricing in the live range above so customers can compare real pump options rather than relying on a generic estimate.

What Can Change the Installed Price?

  • Pump brand and model.
  • Required flow and pressure.
  • Traditional versus variable-speed design.
  • Surface versus submersible pump.
  • Existing pump removal.
  • Suction pipework.
  • Discharge pipework.
  • Valves and controllers.
  • Rain-to-mains integration.
  • Electrical requirements.
  • Tank condition and plumbing.
  • Distance and elevation.
  • Installation access.
  • Filtration connected to the pump.
JR Installer Verdict: Compare the complete pump installation, not just the bare pump price. A cheaper pump can become the more expensive option if the wrong model creates poor pressure, cycling or another replacement later.

Water Pump Maintenance

Many domestic pumps require relatively little routine attention, but the complete water system should still be checked when performance changes.

Useful Checks Include:

  • Water leaks around the pump and fittings.
  • Unusual pump noise.
  • Frequent or rapid cycling.
  • Reduced pressure or flow.
  • Blocked filters or strainers.
  • Tank water level.
  • Controller warnings or alarms.
  • Pressure tank condition where fitted.
  • Weather protection.
  • Suction leaks.
  • Electrical supply and visible cable condition.
JR Installer Verdict: A sudden change in noise, cycling, flow or pressure is worth investigating early. Pumps are usually easier to diagnose before they completely stop supplying water.

What We Look for When Choosing a Water Pump

Real Demand, Not Maximum Numbers

The required duty point matters more than the pump's maximum flow or maximum pressure in isolation.

The Existing Pipework

A powerful pump cannot completely overcome poor pipe sizing, severe restrictions or badly designed suction plumbing.

The Water Source

Mains water, an above-ground rainwater tank and a submersible tank setup all create different pump requirements.

How Often Multiple Outlets Run

A pump for one garden tap has a very different duty from a large family home using several fixtures at once.

Noise & Location

Pump placement can matter nearly as much as the advertised sound level, particularly beside bedrooms and neighbouring properties.

Long-Term Serviceability

Brand support, controller availability, installation access and practical replacement options all matter over the life of the pump.

Common Water Pump Sizing & Installation Mistakes

Buying the Biggest Pump

Oversizing can create excessive pressure, cycling, noise and unnecessary purchase cost.

Using Maximum Flow as the Size

Maximum flow does not tell you how much water the pump delivers at the required pressure.

Ignoring Suction Conditions

Poor suction pipework can limit a surface pump before its discharge capability becomes relevant.

Ignoring Pipe Size

Undersized plumbing can create large friction losses and reduce the benefit of a new pump.

Ignoring Filter Pressure Drop

Whole-house filters need to be included when assessing the pressure available after the pump.

Replacing the Pump Without Diagnosing the Fault

Leaks, controllers, valves and plumbing restrictions can make a good pump look faulty.

Installing Too Close to Bedrooms

Pump noise and vibration can become far more noticeable when placement is not considered before installation.

No Future Service Access

Pumps, controllers and valves should remain accessible for inspection, maintenance and eventual replacement.

Water Pump FAQs

What is the best water pump for a house?

There is no single best pump for every house. The right model depends on the water source, number of outlets, peak flow, required pressure, elevation, pipework and whether the pump is boosting mains water or supplying water from a tank.

How do I know what size water pump I need?

Pump sizing should consider the required flow and pressure at the same time, along with elevation, pipe length, pipe size, suction conditions, filters and the number of outlets likely to operate together.

Is a bigger water pump better?

Not necessarily. An oversized pump can create excessive pressure, unnecessary cycling, noise and additional cost. The goal is to select a pump that comfortably meets the real duty of the system.

What is the difference between pump flow and pressure?

Flow describes how much water the pump moves, commonly in litres per minute. Pressure describes the force available to move that water through the plumbing and operate fixtures. A useful pump needs to provide both at the required operating point.

What does metres of head mean on a water pump?

Head is a way of expressing the energy or pressure capability of the pump. Approximately 10 metres of water head corresponds to about 98 kPa, although real systems also need to account for pipe friction, elevation and other pressure losses.

What is a pump duty point?

The duty point is the combination of flow and pressure or head the pump needs to deliver when operating in the actual plumbing system.

Can a pump increase my mains water pressure?

A suitable booster arrangement can improve pressure on appropriate installations, but the existing mains supply and plumbing should be assessed first to confirm the cause of poor pressure and the correct installation method.

Why is my water pressure low even with a pump?

Possible causes include an undersized pump, poor suction, restrictive pipework, blocked filtration, incorrect controls, excessive elevation or another plumbing restriction.

What is a rainwater tank pump?

A rainwater tank pump moves stored rainwater from the tank and provides useful pressure to connected taps, toilets, laundry, irrigation or household pipework.

What is a rain-to-mains pump?

A rain-to-mains system uses rainwater when available and incorporates a controlled mains-water backup arrangement when the tank supply cannot meet demand.

What is the difference between a surface and submersible pump?

A surface pump operates outside the tank and draws water through suction pipework. A submersible pump operates inside the water source and pushes water from within the tank.

Are submersible water pumps quieter?

They can reduce externally noticeable pump noise because the pump operates inside the tank, although total system noise also depends on pipework, controls and installation.

What is a variable-speed water pump?

A variable-speed pump changes motor speed as demand changes and can maintain more consistent pressure across a range of household flow conditions.

Why does my pump keep turning on and off?

Repeated cycling can result from leaks, pressure tank problems, controllers, non-return valves, pressure loss or an incorrectly configured pump system. The cause should be diagnosed before the pump is replaced.

Why does my water pump run when no taps are open?

This can indicate pressure loss from a leaking fixture, pipe leak, valve fault, controller issue or another problem causing the pump system to detect demand.

Why is my water pump noisy?

Pump noise can come from normal motor operation, vibration, mounting, pipework, cavitation, worn components or the pump being installed in a location where sound is easily transmitted.

Does pipe size affect water pump pressure?

Yes. Undersized or restrictive pipework creates friction loss as flow increases, reducing the pressure available at downstream fixtures.

Can a water filter reduce pump pressure?

Yes. Every filtration system creates some resistance to flow. Pressure loss depends on housing size, cartridge type, water flow and how loaded the cartridge has become.

Should I repair or replace my water pump?

That depends on the fault, pump age, parts availability, repair cost and whether the existing pump is correctly sized. A diagnosis can establish whether the pump itself or another part of the water system is responsible.

Do water pumps need electricity?

Most residential pressure and rainwater pumps require electrical power. The exact electrical requirements depend on the selected model and installation.

Can a water pump be installed outside?

Many pumps are used in external installations, but the exact location and weather protection must suit the manufacturer's requirements and allow safe future servicing.

Do you install DAB water pumps?

Yes. JR's current range includes DAB household pressure, smart booster, jet and submersible pump options.

Do you install Davey water pumps?

Yes. JR's current range includes Davey pressure pumps and RainBank rainwater harvesting systems in both surface-mounted and submersible configurations.
