Claremont Plumbers for Gas Lines, Sewer Laterals and Mid-Century Homes

A range, dryer, fireplace or tankless heater added to a house built in the 1960s can overload its original gas line. The plumber adds up the load on the line, checks the pipe size over the run, and pressure tests the new work before it goes in service. The city's page on when a permit is needed lists plumbing work, and the Building Division on (909) 399-5471 can say whether a given gas job needs one.

If you ever smell gas, get out and phone the gas utility from outside. For the planning questions, see gas piping work.

The City of Claremont owns and maintains the sewer mains, about 122 miles of them, and property owners maintain the lateral from the house to the main. The city's sewer page tells owners to have a plumber confirm the problem is not in the lateral before calling the city. Community Services takes sewer backup calls at (909) 399-5431, Monday to Thursday, and the Engineering Division at (909) 399-5465 can help you locate a lateral.

After hours the sewer page points callers to the police non-emergency line, (909) 626-1296. A plumber with a camera can show where a lateral is cracked, rooted or sagging, and fixing a sewer line explains the options.

One fixture draining slowly is a branch problem; several together point to the main line. Telling the dispatcher which fixtures are affected helps send the right equipment, and a camera shows whether the cause is grease, roots or a damaged section. For the methods, see clogged drain service.

The median Claremont home was built in 1966, about 60 percent before 1970 and roughly 9 percent before 1940, by our count of the Census tables. Older supply lines leak at joints and corroded sections. Golden State Water, not the city, supplies the water, so a leak before your meter is Golden State's to handle at 1-800-999-4033; after the meter it is yours.

Acoustic and thermal tools locate a hidden leak; water leak detection explains the steps.

When a house with original piping has several leaks, replacing the lines can beat repairing them one at a time. We did not find a source on which pipe materials are common in Claremont, so the plumber should identify what is in your walls. The city lists "water or sewer line replacement" among work that needs a permit. See pipe replacement.

Golden State's 2025 report lists hardness averaging 190 mg/L, which works out to roughly 11 grains in a gallon, with sodium of 29 mg/L. That is enough scale to clog aerators and stiffen cartridges. The report mentions softeners only in a glossary note about grain units, so treatment is your choice. For repairs, faucet, toilet and fixture repair covers the symptoms.

Slab leaks, tankless and water heaters. We found no foundation data for Claremont; see leaks under the slab, tankless water heater service, water heater replacement and repairing a failing water heater. The city's permit page lists water heater replacement, relocation or installation.
