Ontario — San Bernardino County
Your pressure problem, explained
Ontario splits between historic downtown homes — many with aging pipe and no regulator at all — and the new Ontario Ranch builds with modern valves. Both ends of that spectrum need pressure verified, for opposite reasons.
Municipal systems deliver 80–150 psi to the curb so water reaches every home on the grid — but your fixtures, water heater, and supply lines were designed for 40–60 psi. A pressure reducing valve at the main bridges that gap: a bell-shaped brass valve — typically 3/4-inch, 1-inch, or 1-1/4-inch — installed in-line on the copper main. When it wears out (and every regulator wears out), it usually fails open — silently letting full street pressure into your home.
Whether it's a 1940s bungalow or a new build, our free test gives you a gauge reading and an honest answer.

Warning Signs
Signs your Ontario home's pressure is too high
Toilets that run on their own
When supply pressure overwhelms the fill valve, toilets refill randomly and waste water around the clock.
Dripping water heater relief valve
The T&P valve on your water heater drips when pressure climbs too high — ignore it and the tank pays the price.
Leaking faucets and fixtures
Cartridges, supply lines, and seals are built for 40–60 psi. Chronic high pressure makes them weep, drip, and fail years early.
Appliances failing early
Dishwashers, washing machines, and ice makers have inlet valves rated for normal household pressure. High pressure shortens their lives quietly.
What to Expect
Your Ontario regulator job, step by step
Free pressure test
Static pressure tested at the spigot and inside — free, with the gauge reading shown to you.
Regulator assessment
We locate your PRV (or confirm there isn't one) and determine whether it has failed open or worn out.
Written scope
Clear written plan before any work: replacement or new install, set point, and any code-required additions.
Press-fit installation
Old valve out, new brass regulator pressed in with copper and ProPress — no torches, water off only during the swap.
Set & verify
Dialed to 50–60 psi and verified at multiple fixtures. You see every reading before we call it done.
Why It Matters
Code, comfort, and peace of mind
Plumbing code requires a pressure-reducing valve when supply pressure exceeds 80 psi — and most unregulated homes are well past that. A properly set regulator delivers strong, even pressure at every fixture while keeping your plumbing inside what it was built for. Set it once, verified by gauge, and stop thinking about it.
