"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!"

"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"

"Leo and Tony and Able are wonderful and amazing. They installed new shut off valves throughout the house and the main. New P-traps throughout, power washed all my decks and fixed two leaks on the second floor and repaired the ceiling. The most beautiful work was installing a new bathtub and tile surround. Able is an artist! Leo is so fair and honest and his team just works hard every minute they were at my house. Came when they said they would. Gave me updates. Did additional work that I asked them for. I would hire them again in a heartbeat. "

"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."

"Went above and beyond with my new kitchen sink installation. Francisco found some issues with the previous installation (done by a family friend, not a pro) and was very honest with his recommendations/prices and fixed the issues properly. The new sink looks great, lingering issues are finally fixed and best of all, the wife is very happy."

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

"Haven’t completed the job as of yet but I’m sure it will be done correctly. Customer service so far has been top notch. I’ve been kept informed every step of the way. Nice to find people who care. Last company I hired botched the job. Looking forward to completion."

"Steve installed an earthquake gas shutoff valve. He carefully and thoughtfully considered the best way to make it fit in the limited space, and ultimately came up with a super-efficient solution that required a minimum of new piping. He explained and demonstrated how it worked, and how to turn it on and off. As he turned on the pilot light for the water heater after installation, he explained how to do it if I ever needed to do it myself. Quick to respond to my initial inquiry and further questions. Excellent service -- highly recommended!"

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