Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests and make their concerns the basis of our business. Our customer's safety is extremely important, which is why all of our technicians are fully trained, background checked, and drug tested.

"A troublesome shower drain was resolved quickly by Oak Plumbing. I want to recognize Niles, Harris, Jessy, and Amari for their great work. Niles inspected the crawlspace, measured every line, and gave me a fair quote based on my home’s actual layout. Harris cleared space for the new pipes, sketched the floor plan, and confirmed materials. Jessy and Amari replaced all horizontal drain lines—including the garage sink, washer, kitchen sink, two toilets, shower, and two sinks—in tough conditions under the house. This started after another company gave me a flat-fee quote based on “two bathrooms.” Oak Plumbing’s quote was more detailed and more accurate for my 1950s home with 1.5 baths and mixed old materials. Their bid was over 10% better, and I left a deposit that day. I’m grateful for how quickly they solved the problem, especially days before Thanksgiving. As a single mother who relies on Angie’s List, this experience fully met expectations. I highly recommend Oak Plumbing."

Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"NWP installed a new furnace in my home, for which they overcharged me by $3,379, based on the contract they wrote. The job was "completed" in early October, when they demanded the final payment. I asked if they had received approval on the final inspection for the permit, and they assured me they had. In February, while at the Permit Office in Vallejo, I was informed that I still had an open permit with them, that they had not had the final inspection. That permit will soon expire, if it has not already. By that time, one of the ducts they had installed had fallen down and torn; the wires leading to the thermostat had also fallen down across the door. I called and asked them to come out to fix, and to schedule the final inspection. They never showed. When I called to ask where they were, they rescheduled. At that later date, they sent out a technician to survey the problems; he promised he would return the following Thursday to fix them, and would schedule the inspection for Friday morning. None of these things occurred. I texted him and received no reply. So, at this point I have a working furnace, drooping and torn ducts, falling wires, no final inspection, and am missing one register because it was taken to match the size by the technician. I am moving to file a complaint with the Contractors State License Board. I would recommend you find someone else for the job. P.S. Just discovered that their license has been suspended by the CSLB for failure to post a bond."

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