Your Local Plumber
Serving All of Ontario, CA
Our shop is at 2141 E Philadelphia St, Suite R, so Ontario is home turf. It is also a bit older than most of the cities we serve, and the plumbing shows it.
Clogged drains are the call we get most here, and old piping that has failed is usually what's behind them. Below is what we find in Ontario homes, from the cast iron under 1950s and 60s slabs to the PEX in the newest neighborhoods, with real jobs and real prices.

Ontario Homes
What Kind of Plumbing Do Ontario Homes Have?
It depends on the neighborhood. Off the 60 freeway, and along Philadelphia, Haven and Mission, many homes were built in the 1950s and 60s. Most of them sit on slab, some on raised foundations, and the drains under those slabs are mostly cast iron. Older commercial buildings in Ontario have cast iron and galvanized pipe too.
The newer neighborhoods are a different story. Around the new minor league ballpark, home of the Buzzers, most homes are plumbed with PEX and have tankless water heaters.
Cast Iron
Why Is Cast Iron Failing Under Ontario Homes?
Age. Cast iron gives about 50 years before it starts rotting out, and it goes from the bottom of the pipe, where waste runs through it every day. Left long enough, the pipe dissolves.
That is why so many Ontario drain calls trace back to failed piping rather than a simple clog. When we clear a line, we cable it first and then run a camera through it to see why it backed up. If the line itself has failed, our sewer line repair page covers the options.
Hard Water
What Does Ontario's Hard Water Do to Fixtures?
It wears them out early. Ontario's water is very hard, and the calcium builds up inside fixtures. The first parts to go are the cartridges in faucets and shower valves, which can clog and fail within a few years when the water isn't treated.
Treating the water at the source protects them. See our water softener and filtration service.
Water Pressure
What Is the Water Pressure in Ontario?
An Ontario home without a working regulator typically runs 90 to 100 PSI. We set every regulator to 65 to 70 PSI, which is where your fixtures are meant to run.
Replacing a regulator on a typical home, which is 3/4-inch or 1-inch, runs $400 to $900, and more if the water service piping around it has to be rebuilt. Regulators usually last 5 to 10 years, depending on how hard the water is and how much pressure the city sends.
Here is how we test it and what a water pressure regulator replacement involves.
Pricing

On the Job
What Does Replacing an Orangeburg Sewer Line Cost?
On one Ontario job, about $13,000. The main line from the house to the street was Orangeburg, a pipe made of tar and paper that was put in around World War II as the next big thing. It doesn't hold up. We replaced a run of about 90 feet.
Every job is different, so treat that as one real example, not a quote. We explain the material in what is Orangeburg pipe.
On the Job
What Went Wrong on a Newer Home Near the Ballpark?
A fitting on the main line. The house, one of the newer builds next to the ballpark, had a 1 1/4-inch PVC main with a tee that branched off to the sprinklers, and the tee failed.
We dug down about 2 feet right next to the meter and reconfigured the piping. That job came to about $1,300.
