PURETEC WHOLE HOME FILTRATION INSTALLATION
Puretec WU20-25M Installation Brisbane & Gold Coast
JR Gas & Water supplies and professionally installs the Puretec WU20-25M whole-house mains water filtration system across Brisbane, the Gold Coast and surrounding eligible South East Queensland service areas.
The WU20-25M is a twin-stage whole-home filter designed specifically for mains water. Rather than treating one drinking-water outlet, it is installed on the household water supply so filtered water can feed multiple downstream taps, showers, bathrooms, laundries and appliances where the plumbing layout allows.
Puretec specifies a maximum published flow of 60 litres per minute, 1-inch BSP connections and large-diameter 20-inch housings. The supplied cartridge arrangement combines 5-micron sediment filtration with carbon treatment for chlorine, taste and odour reduction.
It is a practical option for mains-water homes wanting straightforward whole-house filtration without moving immediately to UV disinfection, water-softening, reverse-osmosis or a more complex premium filtration system.
Puretec WU20-25M quick answer:
the WU20-25M is a twin-stage mains-water whole-house filter using large
20-inch housings, a 5-micron MB05LD2 sediment cartridge and EC10LD2 carbon
cartridge. Puretec publishes up to 60L/min flow, 25mm / 1-inch BSP
connections, 520kPa maximum pressure and 52°C maximum water temperature.
It requires no electrical supply and is intended for general-purpose sediment,
chlorine, taste and odour reduction throughout the home.

Practical General Filtration
A straightforward option for homes primarily concerned with sediment, chlorine, taste and odour rather than specialist water treatment.
PRODUCT SUITABILITY
Is the Puretec WU20-25M Right for My Home?
A Good Choice If...
Your property uses mains water, has a suitable 25mm connection arrangement and needs general whole-house sediment and carbon filtration at up to 60L/min published flow.
Consider Another System If...
You use rainwater, need UV disinfection, need dedicated hardness or scale treatment, require reverse osmosis, or your household flow requirement exceeds what this system can comfortably support.
JR Should Check First If...
Incoming pressure is high, the water-main size differs from the system connection, mounting space is limited or the home has several high-flow fixtures likely to operate together.
How Does the Puretec WU20-25M Work?
Incoming mains water reaches the filter: the WU20-25M is installed at a suitable point on the household water supply so downstream water passes through the filtration system.
Stage 1 captures sediment: Puretec's MB05LD2 melt-blown sediment cartridge provides nominal 5-micron filtration to help reduce dirt and suspended particles.
Stage 2 uses carbon filtration: the EC10LD2 extruded carbon cartridge provides treatment for chlorine, taste, odour and general mains-water chemical concerns.
Filtered water continues into the home: after treatment, water returns to the household plumbing and can supply connected downstream fixtures.
No electrical supply is required: the system operates from household water pressure with no powered pump, UV lamp or electrical control system.
What Does the Puretec WU20-25M Reduce?
Sediment & Dirt
The first-stage melt-blown cartridge helps reduce dirt and suspended sediment before the water reaches the carbon stage.
Chlorine
Puretec lists chlorine reduction as one of the principal treatment functions of the WU Series mains-water systems.
Taste & Odour
The carbon stage is designed to improve common taste and odour concerns associated with treated mains water.
The WU20-25M is not a water softener, reverse osmosis system or UV
disinfection system.
It should be selected for the treatment functions of its installed sediment and
carbon cartridges rather than being expected to perform specialist water
treatment outside that scope.
Whole-House Filtration vs a Drinking-Water Filter
A normal under-sink filter treats water at one dedicated outlet, typically for drinking and cooking.
The WU20-25M is installed on a main household supply so filtration can apply to multiple downstream fixtures.
This makes it relevant where the household wants sediment and carbon treatment for showers, bathrooms, laundries and appliances as well as kitchen water.
Some homes use both approaches: whole-house filtration for broad household treatment plus a separate point-of-use filter where more specialised drinking water treatment is wanted.
Key Puretec WU20-25M Features
20-Inch Large-Diameter Housings
Twin large-format housings provide more cartridge volume than compact point-of-use filtration systems.
60L/min Published Flow
Designed around whole-home water demand rather than the low flow required at a single drinking-water tap.
5-Micron Sediment Stage
Uses Puretec's MB05LD2 melt-blown sediment cartridge.
Carbon Treatment
Uses Puretec's EC10LD2 extruded carbon cartridge as the second filtration stage.
Stainless Steel Bracket
The system is supplied with a stainless steel mounting bracket and housing wrench.
No Power Required
The standard WU20-25M operates entirely from water pressure and requires no electrical supply.

INSTALLATION REQUIREMENTS
What Is Required to Install a Puretec WU20-25M?
Suitable mains-water supply
Appropriate point-of-entry installation position
Household flow suited to the selected system
Suitable incoming pipe size and plumbing arrangement
Water pressure within Puretec requirements
Pressure limiting where supply exceeds 500kPa
Suitable upstream and downstream isolation arrangement
Strong wall or appropriate freestanding support
Clearance below housings for cartridge removal
Future access for servicing
Suitable protection for the selected installation position
Flushing and leak testing after installation
Water Pressure & Pressure Limiting
Whole-house filtration is installed on the incoming water supply, so pressure affects both system protection and household performance.
Puretec publishes a maximum pressure of 520kPa for the WU20-25M and states that an approved pressure-limiting device must be fitted where line pressure exceeds 500kPa.
Incoming pressure should therefore be checked as part of the installation rather than assuming the existing property pressure is suitable.
Where pressure control is required, the final valve and pipework arrangement should be matched to the property and selected JR installation package.
Whole-House Flow & Pipe Size
Puretec publishes a maximum flow of 60L/min for the WU20-25M, but practical household performance depends on more than the filter rating alone.
Existing mains size, incoming pressure, pipe length, fittings and simultaneous household demand all influence the flow available at taps and showers.
The WU20-25M uses 25mm / 1-inch BSP filter connections, making the existing plumbing arrangement an important part of installation planning.
Whole-house filtration needs to be sized around real household
demand.
Multiple showers, bath filling, washing machines and outdoor taps can create
simultaneous flow demand that a single fixture does not reveal.
Installation Position & Cartridge Access
The WU20-25M uses large 20-inch housings, so sufficient installation space is important.
The filter should be positioned where isolation valves, housing removal and future cartridge servicing remain practical.
Clearance underneath the housings is particularly important because the bowls need to be removed when cartridges are changed.
Where wall mounting is not practical, JR's current product selector also provides freestanding package pathways with supports according to site conditions.
JR Puretec WU20-25M Installation Packages
JR's current live WU20-25M page uses six installation pathways so the scope can reflect whether the system is an exact replacement, wall mounted or freestanding, and whether the existing incoming water main is already exposed.

BRISBANE INSTALLATION
Puretec WU20-25M Installation Brisbane
JR Gas & Water installs suitable Puretec WU20-25M whole-house filtration systems throughout Greater Brisbane for mains-water homes wanting filtration beyond a single kitchen outlet.
Brisbane installations are assessed around incoming water pressure, household flow, pipe sizing, the location of the incoming water main and future cartridge service access.
A straightforward wall-mounted installation on an exposed main can have a very different scope from a property where the main is concealed or a freestanding support arrangement is required.
JR also services Logan, Ipswich, Redlands, Moreton Bay and surrounding eligible South East Queensland areas, subject to current booking availability.
GOLD COAST INSTALLATION
Puretec WU20-25M Installation Gold Coast
JR Gas & Water provides suitable WU20-25M supply and installation across eligible Gold Coast service areas.
The 60L/min twin-stage system can suit family homes wanting sediment and carbon treatment across multiple outlets while retaining a straightforward non-powered filtration setup.
Household water demand, incoming pressure, pipe size, mounting position and cartridge-service clearance should still be checked before the installation is treated as straightforward.
Can the WU20-25M Replace My Existing Whole-House Filter?
Replacing Another WU20-25M
Usually the simplest pathway where the existing pipework, isolation, pressure, mounting position and service access remain suitable.
Replacing Another Twin Filter
Often possible, but housing size, connections, cartridge clearance, flow rating and pressure requirements should be checked before treating the job as like-for-like.
Changing From a Smaller Filter
Upsizing to large 20-inch housings can require additional wall space, pipework changes or a different mounting arrangement.
WU20-25M vs WU20-40M
| Feature | WU20-25M | WU20-40M |
|---|---|---|
| Water Source | Mains water | Mains water |
| Housing Format | Twin 20-inch large diameter | Twin 20-inch large diameter |
| Maximum Published Flow | 60L/min | 60L/min |
| Nominal Micron Rating | 5 micron | 5 micron |
| Connection Size | 1" BSP / 25mm | 1½" BSP / 40mm |
| Stage 1 Cartridge | MB05LD2 | MB05LD2 |
| Stage 2 Cartridge | EC10LD2 | EC10LD2 |
| General Difference | 25mm connection arrangement | 40mm connection arrangement |
The key current manufacturer difference between these two 20-inch mains-water models is the plumbing connection size rather than published maximum flow. The appropriate version should be selected around the property's pipework and installation arrangement.
WU20-25M vs Smaller WU10-25M
WU20-25M
Uses the larger 20-inch cartridge format and Puretec publishes up to 60L/min maximum flow with a 25mm connection.
It can be a suitable fit where whole-house demand justifies the larger cartridge format.
WU10-25M
Uses the shorter 10-inch format with a lower published maximum flow while retaining the 25mm connection size.
It can suit installations where physical space and lower household demand make the smaller format more practical.
WU20-25M vs Rainwater Filtration
WU20-25M Mains Water
Designed for treated mains-water supplies with sediment and carbon filtration aimed at common mains-water concerns.
Rainwater Filtration
Rainwater can require a different filter configuration and may require additional treatment such as UV depending on the source and intended use.
Puretec offers separate rainwater-specific systems rather than describing the WU20-25M as a rainwater product.
Puretec WU20-25M Cartridge Maintenance
| Stage | Cartridge | Function |
|---|---|---|
| Stage 1 | MB05LD2 | 5-micron nominal melt-blown sediment filtration |
| Stage 2 | EC10LD2 | Extruded carbon treatment for chlorine, taste and odour reduction |
Cartridge life varies according to household water consumption, incoming sediment loading, chlorine exposure and other local water conditions.
Pressure loss, reduced flow or changes in water quality can indicate that cartridge servicing is required.
Puretec specifies genuine replacement cartridges for maintaining the intended WU20-25M filtration configuration.
