Common Plumbing Problems in Ontario Homes
The Ontario Municipal Utilities Company runs the city's water service, with more than 45,000 connections. Part of the supply is Chino Basin groundwater treated at desalters that remove salts.
The median Ontario home was built in 1980. The city's fee schedule lists a plumbing permit for a water heater including its vent, and state law requires the new heater to be strapped against earthquakes.
Older Ontario Homes and Newer Ontario Ranch
Ontario has 2 very different housing stocks. Homes near downtown and Euclid Avenue are mostly from the 1950s to the 1970s, with copper or galvanized supply lines and cast iron drains under the slab. Ontario Ranch in the south is new construction with PEX lines. A plumber should know which type you have before quoting a repair.
Slab Leaks
Copper under older slabs pinholes with age.
Water Heater Replacement
Gas tanks with old venting need the vent checked during replacement.
What Affects Plumbing Costs in Ontario
No plumber can quote a firm price before seeing the problem. These are the things that move the cost of plumbing work in Ontario.
- Slab access. Rerouting overhead and opening the floor are priced differently.
- Venting. Old gas vents may need replacing with the tank.
- Finding the problem. Leak locating and camera inspections are separate steps, but they keep the repair itself small.
- Time of day. Many companies charge an after-hours, weekend or holiday fee.
- Permits. When a job needs one, it comes from City of Ontario Building Department, and the plumber usually pulls it.
- Ask for the arrival fee before the plumber heads out, and for the repair price in writing before work starts.
How to Find a Licensed Plumber in Ontario
These checks take a few minutes and prevent most bad experiences, whichever Ontario plumber you end up hiring.
Check the California License
Plumbing contractors in California are licensed by the state. Before any work starts at your Ontario home, ask for the license number and look it up with the Contractors State License Board (CSLB).
Ontario Water Heater Permits
Ontario lists a plumbing permit for a water heater with its vent on its fee schedule, and permit technicians quote the exact total at issuance. Because the vent is included, a gas tank replacement is checked for proper venting. Ask the plumber doing your water heater replacement whether the permit and seismic strapping are in the price.
What to Ask on the Phone
- What is the arrival window?
- Is there a service, trip or after-hours fee?
- For an emergency, will you stop the damage first and quote the permanent repair before starting it?
- What is your license number?
