"Green Arrow Plumbing has been exceptional, and I’m very grateful that I trusted them with such a significant plumbing project. From start to finish, they demonstrated a high level of professionalism and attention to detail. What initially began as two slow-dripping faucets turned into a much larger job after they conducted a thorough inspection beneath my home. Their findings were later confirmed by two other companies, but I ultimately chose Green Arrow because they took the time to clearly explain their assessment and recommendations. In addition, their quote was considerably more reasonable than the others I received. Their team is knowledgeable, thoughtful, and highly skilled. The quality of their work was even confirmed by a contractor friend of mine, who described it as A+ craftsmanship. Green Arrow made the process far less stressful. I feel confident in the work they completed, the investment I made. Call them : )"

"They came out quickly and got the job done. The drawbacks were that the person who assessed the situation was different from the two workmen who came to install the new garbage disposal, and that neither of the workmen spoke English. I had no opportunity to ask whether the existing disposal could be fixed (it was relatively new) or if it absolutely had to be replaced. For a $700 total cost, I would like to have been sure. Having said that, everything works as it should and my sink is working again."

"Our potfiller kitchen faucet began to leak at the wall. Great reviews on Yelp and Nextdoor prompted us to contact Plumbtree Plumbing. Their online appointment facility was very easy to use; an appointment was secured for the same afternoon. A very professional, courteous, and personable plumber, Bruce, diagnosed the problem and made an expert repair for a reasonable cost. We were very pleased. Bruce was genuinely concerned about our home's plumbing. Without any sales pressure at all, he and his equally expert associate, Matthew, made an inspection of our water pipes and discovered three issues: 1) the "water shutoff valve" at the base of the house was actually a gas shutoff valve!, and 2) a number of our water pipes were galvanized pipe instead of the desired/required copper pipe. While under the house, Matthew spotted issue # 3) and photographed it: one of our heating ducts had become disconnected, thus pumping hot air into the crawlspace! So, we are having Plumbtree Pumping come back to make a thorough estimate to correct items 1) and 2). (And our HVAC people will fix item 3)!) Please strongly consider using Plumbtree Plumbing for all your plumbing needs!"

"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!!"

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.
