The property owner is usually responsible for a water pressure regulator that serves only their property and forms part of the private water service. Sydney Water is responsible if it confirms the regulator is one of its network assets.
Does the water meter determine responsibility?
The meter is a useful guide, but its position alone does not prove ownership.
A pressure-reducing or pressure-limiting valve after the water meter, supplying one property, is generally private plumbing. Equipment before the water meter may be a Sydney Water asset, but layouts vary and nearby valves are not necessarily utility-owned.
Responsibility may also differ where a regulator serves shared or strata plumbing. In that case, check the strata plan and ask the strata manager or owners corporation which plumbing the valve serves.
How to confirm responsibility
- Observe the regulator’s position relative to the meter without opening covers or disturbing fittings.
- Check whether it supplies one property or a shared service.
- Ask Sydney Water whether it appears in its asset records.
- If it is private plumbing, have a licensed plumber confirm its function and condition.
Do not adjust, loosen or dismantle the regulator. The service is pressurised, and incorrect work can cause flooding, damage or loss of supply. Replacement or alteration should be left to an appropriately licensed NSW plumber.
If the regulator appears to be private, our Sydney plumbing team can inspect it and confirm the appropriate next step.
