Water Pressure, PRVs and High Water Bills
A pressure-reducing valve (PRV) sits where the line enters the house and lowers street pressure for your plumbing.
Signs of trouble
- Banging pipes or noisy fixtures
- Pressure that surges or drops
- Repeat leaks at fittings
Check it yourself
Screw a pressure gauge onto an outdoor hose bib and read it. Residential pressure above about 80 psi is generally too high. A low reading with a moving meter points to a service line leak.
