Bring Your Own Whole-Home System

What’s involved in the installation

1. Locate and assess the mains — we find your water meter and main entry point, check the incoming pressure and choose the correct position for servicing access.
2. Shut down and drain — the property supply is isolated at the meter and the line drained ready to cut in.
3. Mount the housing — the unit is bracketed to a wall or fence on a solid backing board, at a height where cartridges can actually be changed without draining the system.
4. Cut in and plumb — we cut into the main, install the inlet and outlet connections in the correct flow direction, and transition pipe materials properly where needed (copper, PEX or poly).
5. Fit a bypass — isolation valves either side plus a bypass arrangement, so cartridges can be changed or the filter taken offline without cutting water to the house.
6. Pressure test and recommission — the system is brought back up slowly, purged of air, checked at full mains pressure and every joint inspected.
7. Check the whole house — we run taps through the property to confirm flow and pressure are where they should be, then clean up and remove packaging.

One system per home. A house only needs a single point of entry filter, so unlike our tap and under-sink work there is no multi-unit discount here — each whole-home installation is priced as a complete job on its own.

Why this is licensed work

Cutting into your water main is regulated plumbing work in NSW. Done badly it can drop pressure across the whole house, introduce contamination at the point of entry, or leak inside a wall cavity where you will not see it for months. A licensed plumber connects the system to plumbing standards and leak-tests the work.
