"I have used other plumbers before...none of whom did the work entirely to my satisfaction, and many of whom found ways to increase their "firm" quotes. I chose Drain Pro because of their almost perfect 5-star rating. I now know why they have that rating. The man who took my call was Raymond or Raman (Ramandeep Singh), the company president. He was pleasant, friendly, and gave me a reasonable ballpark quote (assuming no major problems). It was not the lowest estimate to do the job, but I wanted it done right. He arrived right on time. The only part of the job that went smoothly was the bathroom faucet replacement, and it went quickly. The kitchen sink partial-clog turned out to be several heavy accretions of hardened grease in one eight-foot section of pipe that had become CONcretions over the years -- some of the grease had come from previous owners...and likely some from us. He tried the big power-snake twice, but couldn't force the gizmo (heavy steel screw-spring) through the blockage. He slithered into the crawlspace to see if there were some abnormality in the pipes...nope. So up he came -- he took off the gizmo, and forced the bare cable-end through the blockages, back and forth several times -- ran the water to see if the blockage was gone...nope, even worse than before (he felt that some of the smaller blockages had moved, become a "log-jam"). He tried it again with the gizmo...nope. At this point he said there were only two good solutions: (a) cut out and replace the section of pipe with the hardened blockages; and (b) bring in the cavalry with special equipment and do a "hydro-jet" clean out -- both these processes would more than double his original bid. But just to be sure, he tried it once more with just the bare snake-end. And lo & behold, the blockage was gone! ...I hope. Raman said it could come back, and we could do the hydro-jet operation, if needed. Then he rebuilt a toilet (several small problems). The bolts holding the tank on were so bad he had to use a sawzall to cut them off. He replaced all the parts, installed the new flush mechanism, and it is now as silent as can be. Hallelujah! With all the problems he encountered, I expected a demand (or request) for more money. Nope. He stuck with his original bid. As I said at the top, his wasn't the low bid. But he did all the work correctly, kept everything spotless clean, and was friendly and cheerful throughout. Without any hesitation, I strongly recommend this company in general, and Raman in particular."

"We had an issue with our septic line clogging, which turned out to be the result of some pretty problematic installation choices by the previous resident. Trident was recommended to us by another plumber we have used in the past, but who was unavailable for this issue. Landon came out and not only got us flowing again, but diagnosed and repaired the underlying problem. He was extremely professional and friendly, and I would highly recommend him to anyone for their plumbing needs. He even put up with our 4 year old yellow lab, who can be a bit aggressive in his friendliness. Long story short - if you need plumbing work done, call Trident and ask for Landon. You won't be disappointed."

"The plumber arrived with all parts required to replace the hot water heater and accessories. He completed the job, including draining the old tank, installing a new shutoff valve and new water lines. He lit the heater and checked to be sure the system started with no leaks. He came on a Saturday, with no extra charge. Excellent job!"

"Veteran-owned business. Honest, reputable and on time for the appointment. Ross and David spent all afternoon clearing out two clogged drain spouts and replaced/repaired a badly cracked PVC pipe after hydro jetting them. They inserted a snake with a camera and showed me the problem. They also provided a veteranâ  s discount! Thank You. Brad Pesek"

"I went to Mad Pipers for a second opinion after getting a vague and uninformed assessment of my drain issues from a different company. Ragen and Zach not only took the time to figure out the extent of the problem, but they made sure I understood and knew what my options were, without pressuring me to hire them. I respected both their attention to detail and integrity so decided to hire them for the job. Rather than replace the entire drain system as recommended by another company, they discovered the problem areas where roots were growing into the pipes and were able to replace just the necessary sections effectively and efficiently. This included excavating and trenching the line from a tiny crawl space, redirecting the line to a much more practical location outside the house, adding gravel around the new pipe, reconnecting the line to the unaffected section, and complete and tidy cleanup of my yard, all in two days. I have complete faith in these guys and would definitely hire them again for any future plumbing needs."

"Shawn and his crew replumbed our entire house in 3 days while keeping our home useable. We are blown away by their professionalism, work ethic, friendliness, and quality of install. All new water lines in the house, new fixtures, new waste lines, they did a complete system replacement in our home. Shawn and his team explained every step in the process and walked us through what was done and what was left to do at the end of each work day. An amazing 3 man crew in a company full of amazing talent. Harts had previously lined our 100 yr old sewer line and that crew was amazing as well."

"Mark, Geoff, and Tyler were fantastic. They arrived on schedule, made solid recommendations, and were willing to adjust their schedules when I asked (mid-job) to expand the scope of work. I was orginally going to do a partial water line replacement since several contractors were unable/unwilling to do the more risky full line replacement, but Appollo Plumbing found an ingenious (and less risky) way to replace the entire line. I was so impressed that I also asked them to replace my 12 year old electric water heater with a new heat pump water heater. They did a great job and were very friendly and professional. Appollo Plumbing is officially on my list of reliable, dependable, top-notch professionals to call when I need help."

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