Plumber in Ontario, CA
Licensed, owner-operated plumbing from nearby Rancho Cucamonga, with 24/7 emergency service and honest upfront pricing.
W.P. Plumbing is based just up the road in Rancho Cucamonga, so Ontario is home territory for us. Billy runs the company himself, and when you call (909) 727-2959, you get a licensed plumber who answers day or night, every day of the year. For emergencies, we're often on-site within 60 minutes.
Ontario's housing puts real demands on plumbing. The older homes near downtown and Euclid Avenue often still run on original galvanized or cast iron pipe that's past its useful life. You see it as low water pressure, rusty water at the tap, or drains that back up every few months. Out in Ontario Ranch, the homes are newer, but hard water is already scaling up tankless water heaters and fixtures across the region.
Either way, you get the same deal from us: upfront pricing before work starts, no surprise charges, and workmanship we guarantee. We treat your home like our own and we don't cut corners. Free estimates on major projects like repiping, slab leaks, and main lines.
Plumbing Problems We See Most in Ontario
In the older neighborhoods near downtown and Euclid Ave, the calls are usually about aging pipe. Galvanized supply lines corrode from the inside, so pressure drops and water turns brown after a vacation. Cast iron sewer laterals crack and let roots in, which shows up as gurgling toilets and slow drains in more than one room. A sewer camera inspection tells you exactly what's underground before you spend a dime on repairs. Slab leaks are common in these homes too. Warning signs are a warm spot on the floor, a hissing sound when everything's off, or a water bill that jumps for no reason. We locate the leak precisely so the fix stays small.
In Ontario Ranch and other newer tracts, hard water is the main enemy. It scales up tankless water heaters, clogs aerators, and leaves spots on every glass shower door. Regular water heater flushes and a Halo 5 whole-house filtration system protect the equipment you already paid for. Whatever part of Ontario you're in, we'll tell you plainly what's wrong, what it costs, and what can wait.

We're based in Rancho Cucamonga, just north of Ontario, and we run 24/7/365 emergency service. For urgent problems like a burst pipe or a sewage backup, we're often on-site within 60 minutes. Call (909) 727-2959 any hour and you'll reach us, not an answering service.
Do you charge for estimates in Ontario?
Estimates on major projects are free — that covers repiping, slab leak repairs, and main sewer or water lines. On every job, you get the full price upfront before we start, and that price doesn't change. No surprise charges, no add-ons at the end. That's how Billy runs the company.
My Ontario home was built before 1970. Should I be worried about my pipes?
Not worried, but informed. Galvanized supply lines and cast iron drains from that era are usually near the end of their life. Watch for low pressure, discolored water, and repeat drain backups. A sewer camera inspection and a pressure check will tell you exactly where things stand.
