"If I can give this plumbing company zero stars I would. I had a slab leak, and this company came out for leak detection. I was told that I have two leaks and they cut two lines. They were charging almost 65000 for rerouting two lines. My insurance company also brought their own plumbers and did their leak detection and they found only one leak. The adjuster called RT Olson a fraud company and he almost declined my claim. The insurance refused to fix the two cut lines. They only covered one line and I had to pay for the other line out of pocket. I asked RT Olson to fix the other line that he cut and was not leaking but he refuse to take responsibility. Then he send me an invoice for the leak detection and threatens me to take it to collection and add extra fees. This company is a fraud."

Don't flush your money down the drain when your plumbing goes out! Trust Corsa Plumbing and Rooter to get it done right. We are available for you day or night for all types of plumbing service.

"I feel that I was very lucky have chosen Corsa Plumbing to do diagnose and replace 2 sewers for me. One in Lafayette and one in Pleasant Hill. Ray, was easy to work with and he did a great job of advising me on the existing problems and explaining what they would do to fix them. The camera inspection of the sewer line and the estimate were free. I was present when he did them. Both of the bids were fair, but do not include the cost of County permits. I will highly recommend you get a bid from Corsa Plumbing. You won’t regret it. You can hardly tell that the sewer was replaced Steve Walsh, retired Realtor and property manager for residential homes."

FAQs for water main install, replace or repair projects in Piedmont, 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.
