"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 zero stars were an option, I would choose it. They failed to show up for their scheduled appointment, never followed up, and did not respond to the home insurance company assigned to handle our case. As a result, absolutely nothing moved forward. Because of their inaction, our home has been without heat in the middle of winter for 13 days and counting. This is not a minor inconvenience?it?s a serious failure. I regret working with them. This has been an extremely frustrating and unacceptable experience"

FAQs for sewer main install, replace or repair projects in Knightsen, 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.
