"I had a backup in my main sewer pipe and Jess Plumbing came out and did a thorough inspection, he then found that my main sewer pipe was incorrectly installed by the previous installer. To make a long story short, this guy knows what he is doing, has the equipment including cameras and an excellent team. They did an AMAZING job at a FAIR price. Replacing the main sewer pipe is no easy job, but they were able to do it and do it right. They also cleaned everything up at the end of the day and even planted back the plants that had to be removed during the process!"

"I had Plumbtree plumbing out when my front hose connector wouldn't stop leaking. I called them and they where able to come out the same day!! They accessed the problem and told me that the main house shut off was also not functional and told me the benefit of a new main shut off. After the detailed explanation they got right to work. The work looks very nice and I will trust them with all my future plumbing work. Thanks Plumbtree!!!"

"Solid customer service and the plumber that did the thankless install did a great job. I had a frozen valve and they were able.to repair that on the fly. Their price was competitive with another quote I got. When asking for quotes for a water heater install, Aaron realized I bought the wrong type for my situation and pointed me in the right direction. I will absolutely use these guys for any future plumbing projects."

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend. "

"We thought we needed just our washer drain unclogged so we called the company that had fixed that before, you guys. Guys came out. Under the house they discovered rusted sewer lines. When we had our plumbing redone years ago, the company who did those did not remove the old lines. Those old lines were up against the sewer lines and were corroding our sewer lines. So we had to replace the sewer lines. A broken line just before the city line was discovered so we had to replace that too. Anyhow, we so appreciated the kind workers who smiled and waved at us. They worked around our water schedule as we have a physically disabled adult son we care for. They let us watch all the things they had to do. I took pictures and the guys were fine with that. My brand new front yard was not ruined by trenchless sewer system that went in. And my yard looks like we never had sewer lines done. It was amazing. Yes, we would recommend you to all."

"We cannot express our gratitude enough for having Cornelio on the team during our comprehensive drain and sewer pipe replacement. In the midst of my recovery from a major accident that required two surgeries, we were hit with a severe plumbing issue. Every drain in our house was nearly unusable, among other challenges we encountered. Amidst all this chaos, Cornelio was a beacon of positivity. His professionalism was evident, but what stood out even more was his genuine care and concern. Every interaction was complemented with him inquiring about my well-being and eagerly awaiting updates on my recovery. Despite the project's unexpected complexities, Cornelio and his team ensured it was completed swiftly without compromising the quality of their work. If ever the need arises (though I hope we don't have any more plumbing issues for a long time!), I would hire him without a second thought. A heartfelt thank you to Cornelio and the team!"

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