"Very well done! Tennant called to notify us of a leaking garbage disposal unit. Received a phone call when technician (Raman) arrived with a clear diagnosis before work was to be completed. Used an Angie's list special that was honored with no up-charges or additional work added. Drain Pro is now my go-to for all plumbing needs."

"I called Rescue Rooter to come out and clear out a blockage in my sewer line. Chad and Albert came out quickly and got to work. They also put a camera down into the sewer line and had me watch as they went through the line. I saw the various problems in our one hundred year old sewer line. They spent a good deal of time examining the sewer line and also identifying the spot where it becomes a shared line with our neighbor. They presented a number of options of how to repair the deteriorating sewer line along with the different prices for that work. Chad and Albert both explained the different options clearly to my wife and I. They were very friendly and professional."

"We were in a jam. We are attempting to buy our first home. We had our inspection scheduled and on the morning of, we learned of a potential plumbing issue. There was a report filed with the city stating that a couple of years ago there was some kind of sewer back up. This house is old, so I wanted to make sure we weren't signing up for any potential problems. I called around to local plumbers in the area. NONE of them were able to accommodate our need on this shortened time frame. I got Zach's number from a contractor friend of mine and in a last ditch effort gave him a call. Unlike some of the other plumbers I'd spoken with, Zach validated my concerns and informed me that he would recommend that I have my system inspected. He was very patient with my partner and I, making room for us that evening to show up in exemplary fashion. He did a full inspection of our sewer lines with a camera and explained to us what the different piping meant. He then tested our water pressure and advised us to request that the seller offer concessions to cover the cost of putting in a pressure reduction valve. He explained the reasoning behind his recommendations and took time to insure that we understood why he was recommending these services. He also took the time to explain and answer questions about potential upgrades as my partner wants to upgrade the hot water tank. He outlined different product options and explained with great knowledge and detail the differences between the products. I would highly recommend this company. If we get the home we will definitely be having this company come back and preform the necessary work that is needed for our new home."

"I highly recommend Pace Plumbing. 3 years ago they installed a new bathroom for me in an unfinished basement. Work is superior. Since then I have used them for several rentals and for other issues at my home. I am impressed beyond words and I highly recommend them. They are on time! they communicate and they are highly skilled plumbers. Great company to work with."

"Jerry was very enjoyable and professional in replacing a bent lead toilet connection which had leaked at the toilet. He replaced the old lead connection to the cast iron sewer pipe with modern ABS pipe and installed a flange to attach the new toilet to when the floor is completed."

"I had an amazing experience with the crew at Brewer Sewer! The office was quick in getting me scheduled for a free estimate where the project manager came out and gave us an estimate and took the time to explain what was going on. The crew that came out for repair were friendly, professional and knowledgeable. I recommend them to anyone with a sewer issue. "

FAQs for sewer main install, replace or repair projects in Mercer Island, WA

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.
