Questions and answers
It holds the water pressure inside your house at a steady, safe level, however high the pressure in the street goes. That protects pipes, taps, toilets and the hot water unit.
Yes, the two names are used for the same job. You may also see a combined valve on the cold inlet of a hot water unit that does this alongside other functions.
If a gauge at the front tap shows high pressure, or your relief valve drips, your pipes bang or fittings keep failing, probably. A pressure test answers it properly.
High mains pressure is one of the common reasons, and a valve that is worn out is another. We test the pressure first, because replacing the relief valve will not fix a pressure problem.
Set correctly, it takes the harshness out of the flow without leaving the shower weak. If your pressure is already low, a valve is not what you need, and we tell you so.
No. In NSW, fittings that regulate water are licensed plumbing work, and a wrongly set valve can starve the house or leave it unprotected.
