First Class Riverside plumber serving all of Riverside County and the surrounding area. Receive a free inspection and quote, same day service, and family-friendly service.

"After the gas company refused to turn on our gas due to leak, I searched for gas leak service through Angies. First Class plumbing called and I asked them to perform a test to find out the source of the leak. I agreed to pay them $360 for this service which would be applied to the repair cost should I have decided to choose them for repair. The did a pressure test, confirmed the leak. However, they guessed where the leak was. They said the leak is somewhere underground between the gas meter and where the gas pipe enters teh house (~28 feet). They told me replacing that under-concrete pipe would cost me $9000 and if I do the post repair concrete patch, it would cost $7,000. I asked them to change the whole gas pipe in the yard (b/c it was old), they said $15,000 if I do the post-repair concrete path myself. Based on their statement I signed a contract for $15,000 to replace the whole gas piping in the backyard. Before they were going to show up next day, I asked them to delay the start of the work until Monday (3 days delay). I asked another gas company to do the diagnosis. The leak wasn't in the part of the gas pipe that was going from meter to the place the pipe enters the house. He isolated the segment that was causing the leak, then the leak was gone. I can send you the diagnosis from both companies. I would like First Class piping to pay me my $360 b/c their diagnosis was erroneous. Not only would I have paid the $7000 without having fixed the leak, but I would have damaged the concrete in the yard as well. In their diagnosis, First Class is saying there are Ts under the ground etc. which is absolutely to the case. He would have seen there were no Ts had he used his borescope camera as I asked him to do. I am asking them to pay me back my $360 which is the least they should do."

FAQs for water main install, replace or repair projects in Walnut, CA

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
