"6/26/25 We had been trying to unclog our pipes from the kitchen sink and bathtub (as we thought they ran with the same pipe, which it did) and just unable to do it. My husband sent a text last night and at 3:25pm today, Tryson was here. My husband explained what was going on and what we tried to do. He took a look at everything, explained what needed to be done and got right on it. It took about an hour and a half but, he got it done!! He even put the pipes under the sink back together for us. The price was way less than we thought it was going to cost. Tryson was friendly, courteous and very professional. He did a FANTASTIC JOB!!! We will always support local and will always support Raptor Rooter!!! If I could give them 1000☆'s I would!! We highly recommend Raptor Rooter!!!"

"I highly recommend Lukas for your excavation needs. I just finished building a house in North Spokane where I worked as my own general contractor. I didn?t have any knowledge or experience in excavation, sewer/water lines, digging in the street, or working with the city on the permit process. Lukas helped me with it all including preparing the site for footings, foundations, grading the alley and driveway and was also able to provide the street obstruction permit and bond (which I could not get). Lukas also helped with removing 4 trees and even hauled off them + many other loads of construction debris. He gave me guidance on all the plumbing parts, water lines, suppliers even helped me connect them all the way to my main line in the house. The workmanship, attention to detail and professionalism was exceptional and I was able to save a considerable amount of money. Thank you Lukas."

"Had some Orangeburg pipe replaced before we moved in and they absolutely DESTROYED our front yard. Going to be a huge project trying to fix and we got zero explanation or care in the process about fixing it. Never using this company for anything again."

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