Pressure regulators and relief valves in San Gabriel
With five water companies serving the city, incoming pressure varies street to street. A gauge reading settles it. Text (310) 628-9399.
Five suppliers, different pressures
San Gabriel's water comes from several companies, and pressure at the curb is not the same everywhere. Some homes need a regulator; others had one fail years ago.
We read static pressure and check whether a regulator is present and holding.
Replacing a worn regulator
A regulator that lets pressure creep up gets replaced at the main line, and we set it to a moderate level.
Heater relief valves
The temperature and pressure relief valve is tested and replaced if it drips, sticks or shows corrosion.
We also check the discharge tube and where it ends.
Night-time pressure
Pressure in the mains can rise at night when neighbors stop using water. A gauge with a max needle captures that peak.
That reading tells us whether the regulator is holding.
Questions from San Gabriel homeowners
How do I know if I have a regulator?
Look near the main shutoff for a bell-shaped valve. We can confirm.
Why does my relief valve drip only at night?
Pressure can rise when demand drops. A gauge test shows it.
