No. In Sydney, installing a pressure reducing valve on residential drinking-water pipework is regulated plumbing work and requires an appropriately licensed plumber.
Why it is not a DIY job
Installation involves cutting into a pressurised potable-water supply. Incorrect valve selection, positioning or adjustment can cause leaks, water damage, contamination or unsuitable downstream pressure.
A licensed plumber will:
- measure the incoming and downstream water pressure
- select a compatible valve of the correct size and pressure rating
- install it in the specified flow direction and an accessible position
- set or verify the downstream pressure for the property
- test the completed work for leaks.
There is no universal pressure setting suitable for every property. The plumber must consider the plumbing system, applicable requirements and the manufacturer’s instructions.
What you can do safely
You can observe the leak without removing fittings, move belongings away and contain minor water where practical. If necessary, use the property’s accessible water supply shut-off, but only if it operates easily and you can do so safely.
Do not cut or dismantle pipework, adjust the valve or force a seized shut-off. If water is near electrical equipment, keep clear and seek urgent professional help.
