What this job involves
Street pressure varies with elevation, the neighbourhood and how far you sit from a pumping station. Too much of it wears out faucet cartridges, toilet fill valves, appliance hoses and the water heater’s relief valve. A pressure reducing valve, fitted just downstream of the house valve, steps it down to a steady figure for every fixture in the home.
How the job goes
- Thread a gauge onto a laundry or outdoor tap and read static pressure.
- Check whether it creeps upward overnight, a sign of thermal expansion.
- Fit or adjust a reducing valve after the house valve.
- Add an expansion tank where the closed system needs one.
- Re-test and check the heater’s relief valve.
Warning signs on your pipes
- A thud in the walls when a tap snaps shut.
- Fill valves hiss and wear out quickly.
- The heater’s relief valve dribbles.
- Washer hoses have burst.
- Faucets spit hard when first opened.
From the job notes
A reducing valve turns the plumbing into a closed system, so water expanding as the tank heats has nowhere to go.
A reducing valve turns the plumbing into a closed system, so water expanding as the tank heats has nowhere to go. An expansion tank on the cold feed to the heater absorbs that swell and spares the relief valve.
Reducing valves wear too. If yours went in many years ago and the gauge is creeping, it may need a rebuild or replacement.
