"My elderly mother needed a new water heater . I gave her the contact info for a great, honest plumber. But due to her dementia, she forgot and ended up having a neighbor call a plumber, they chose Albert Nahman . Two plumbers came out and spoke with her and my 85 year old uncle and they were convinced to hire them at a price of over $6k (which, if you can believe, included the "senior discount"). My mom and uncle are clearly confused and easy to take advantage of, and these guys went above and beyond to take advantage of them, charging 4 times what this job should have cost. I called and spoke to a manager and got a ridiculous story of how complicated this job was, and how they were charged a reasonable price. I took away that this company is corrupt from top to bottom. If you want to be taken advantage of, charged way more than any decent plumber would charge, and then treated like an idiot who doesn't know that they are being cheated, this is the company for you!"

"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."

"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 sewer main install, replace or repair projects in Alamo, CA

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
