PURETEC REVERSE OSMOSIS SUPPLY & INSTALLATION
Puretec ROS2700 Installation Brisbane & Gold Coast
JR Gas & Water supplies and professionally installs the Puretec ROS2700 continuous-flow reverse osmosis water treatment system across Brisbane, the Gold Coast, Logan and surrounding eligible service areas.
The ROS2700 is designed for customers wanting a higher level of point-of-use drinking-water treatment than a conventional carbon-only under-sink filter. It combines carbon pre-filtration, two reverse osmosis membrane elements and post-filtration in a compact continuous-flow system.
Unlike many conventional residential reverse osmosis systems, the ROS2700 does not rely on a small pressurised storage tank. Puretec rates the system for up to 2,725 litres of production per day under suitable operating conditions.
Correct system selection still depends on incoming water quality, pressure, under-sink space, drain access, connection points and the way purified water will actually be used in the home.
Puretec ROS2700 quick answer:
the ROS2700 is a continuous-flow reverse osmosis system designed for potable
water supplies. Puretec publishes production of up to 2,725L per day, a nominal
0.0005-micron membrane rating, 275–520kPa system pressure specification and
4–38°C inlet-water range. It uses line pressure rather than an electric pump
when adequate pressure is available and requires both a purified-water outlet
and reject-water drain connection.

A useful option where the household prefers a continuous-flow RO design instead of a conventional reverse osmosis system using a separate small pressure tank.
PRODUCT SUITABILITY
Is the Puretec ROS2700 Right for My Home?
A Good Choice If...
You want a dedicated reverse osmosis drinking-water system, expect regular purified-water use and have suitable mains pressure, cupboard space and a practical drain connection.
Consider Another System If...
Your main goal is only taste and chlorine improvement, you want whole-home filtration, or the incoming water conditions sit outside Puretec's published operating limits.
JR Should Check First If...
Water pressure is uncertain, the property uses a non-standard water source, cupboard access is tight, hardness is elevated or there is no practical reject-water drain connection.
How Does the Puretec ROS2700 Work?
Incoming water is pre-filtered: water first passes through the ROS-CB01 carbon pre-filter before reaching the reverse osmosis membranes.
Line pressure drives reverse osmosis: incoming water pressure pushes water through the semi-permeable RO membrane elements without requiring an electric booster pump where the minimum pressure requirement is met.
Product and reject water separate: purified product water passes through the membrane while a concentrated reject stream carries separated material away.
Post-filtration finishes the process: product water then passes through the ROS-CB02 post-filter before travelling to the drinking-water outlet.
Reject water is discharged: the installation therefore requires an appropriate drain connection as part of the reverse osmosis process.
Continuous-Flow Reverse Osmosis
The ROS2700 differs from many conventional residential RO systems because it does not depend on a separate small pressure-storage tank to hold treated water.
Instead, Puretec uses two RO membrane elements to provide comparatively high continuous production from incoming line pressure.
Puretec publishes maximum system production of up to 2,725 litres per day. Actual output can vary with incoming pressure, temperature, dissolved solids, cartridge condition and other water characteristics.
Published production is not a guaranteed tap flow under every
condition.
Reverse osmosis output is affected by water pressure, temperature, membrane
condition and incoming water quality.
Reject Water & Drain Connection
Reverse osmosis does not turn all incoming water into product water. Part of the incoming flow becomes purified product water and part becomes reject water that carries concentrated impurities away from the membrane.
Puretec notes that the product-to-reject ratio is generally around one part product water to two parts reject water.
The reject stream is normally connected to a suitable drain, so practical drain access is an important part of under-sink installation planning.
Water conditions and operating pressure can affect the actual recovery and reject-water volume.

INSTALLATION REQUIREMENTS
What Is Required to Install a Puretec ROS2700?
Suitable potable cold-water supply
Incoming pressure within the required operating range
Pressure limiting where incoming pressure exceeds Puretec's limit
Adequate under-sink or cupboard space
Practical cartridge and membrane service clearance
Suitable product-water outlet arrangement
Cold-water isolation and connection point
Suitable reject-water drain connection
Water quality within Puretec operating limits
Additional pre-treatment where site conditions require it
Secure mounting or positioning of the system
Flushing, commissioning and leak checks
Water Pressure Matters
The ROS2700 depends on incoming line pressure to drive the reverse osmosis membranes.
Puretec publishes a system pressure range of approximately 275–520kPa and specifies that an approved pressure-limiting device must be installed where line pressure exceeds 520kPa.
Low pressure can reduce production performance, while excessive pressure needs to be controlled before the system.
This is why water pressure should be treated as part of system suitability rather than simply connecting the ROS2700 to any available cold-water line.
Water Quality & Pre-Treatment
Reverse osmosis membrane life and system performance are influenced by the quality of the incoming water.
Puretec publishes operating limits for hardness, dissolved solids, chlorine, manganese, iron and silt density. Water outside these limits may require additional treatment or a different system approach.
The ROS2700 is designed for potable water supplies.
Puretec states that it should not be used on microbiologically unsafe water or
water of unknown quality without adequate disinfection before or after the
system.

BRISBANE INSTALLATION
Puretec ROS2700 Installation Brisbane
JR Gas & Water installs the Puretec ROS2700 across eligible Greater Brisbane properties for households wanting a high-production reverse osmosis drinking-water system.
Brisbane installations are assessed around available cupboard space, cold-water pressure, reject-water drainage, servicing access and whether the existing water conditions fit Puretec's operating requirements.
A straightforward mains-water kitchen installation can be very different from a property needing pressure control, additional pre-treatment or plumbing alterations, so the selected installation package should reflect the actual site.
GOLD COAST INSTALLATION
Puretec ROS2700 Installation Gold Coast
JR Gas & Water also supplies and installs the Puretec ROS2700 across eligible Gold Coast service areas.
The compact continuous-flow format can work well in suitable kitchens, renovations and butler's pantries where a dedicated purified-water supply is required without a conventional RO pressure tank.
Water pressure, drain access, cupboard layout and cartridge-service clearance should all be confirmed before the installation is treated as straightforward.
Can the ROS2700 Replace My Existing Water Filter?
Replacing Another ROS2700
Usually the simplest pathway where the existing plumbing, drain connection, pressure and installation location remain suitable.
Replacing a Standard Under-Sink Filter
Often possible, but reverse osmosis requires a reject-water drain connection and has different pressure, space and servicing requirements from a basic carbon filter.
Replacing a Tank-Style RO System
The ROS2700 can remove the need for a conventional small pressure-storage tank, but existing faucet, drain and plumbing arrangements still need to be checked for compatibility.
ROS2700 vs Standard Carbon Under-Sink Filtration
Puretec ROS2700 Reverse Osmosis
Uses pre-filtration, semi-permeable reverse osmosis membranes and post-filtration to create a separate product-water stream and reject-water stream.
Better suited when the household specifically wants reverse osmosis treatment rather than only conventional cartridge filtration.
Standard Carbon Under-Sink Filter
Typically offers a simpler installation without an RO reject-water stream and can be a practical fit where the main goal is improving taste, odour, chlorine and selected particulate contaminants.
It may be the simpler fit where reverse osmosis treatment is not actually required for the household's water goals.
Continuous-Flow RO vs Tank-Style Reverse Osmosis
ROS2700 Continuous Flow
Designed for comparatively high direct membrane production and does not rely on a separate small RO pressure-storage tank.
A good fit where higher ongoing purified-water production and reduced cupboard clutter from a separate tank are priorities.
Conventional Tank RO
Stores treated water in a pressure tank so water can be delivered from a stored reserve even when membrane production is relatively slow.
It may suit lower-demand drinking-water applications where the tank can be accommodated comfortably.
ROS2700 Cartridge & Membrane Maintenance
| Component | Function | Puretec Published Service Guide |
|---|---|---|
| ROS-CB01 | Carbon pre-filter | Approximately 6–12 months or up to 37,850L, depending on conditions |
| ROS-CB02 | Post-filter | Approximately 6–12 months |
| ROS-RET × 2 | Reverse osmosis membrane elements | Approximately 2–4 years |
Filter and membrane life is not a fixed guarantee. Usage, incoming water quality, pressure, chlorine, hardness and other conditions can shorten or extend service intervals.
