Mainstream Electric, Heating, Cooling, & Plumbing can take care of everything needed for sewer line replacement.

A backed up, clogged, or broken sewer line can cause all sorts of issues, from raw sewage backing up into your home to slow flowing drains and more. Failure to fix these issues when they first occur can be costly to repair, which is why you need the Mainstream team on your side.

Your home’s sewer lines run from the municipal sewer lines directly to the pipes in your home. They’re responsible for taking what you flush down the toilet and drain out of your home and to wastewater plants in and around Spokane. 

When something interferes with the natural flow of water out of your home, you might smell sewer gas or deal with backups in your sinks or shower. This is an issue you need the professionals at Mainstream to help tackle today – not tomorrow.

How do you know something’s wrong with your sewer lines?

The three biggest signs something is going on with your sewer lines include backups, blockages, or the smell of sewer gas. These are usually early indicators there might be something obstructing the flow of water out of your home. 

Mold, especially along the floors or ceiling, can also be a sign of a water leak from sewer lines in your home. In some cases, you may not have a “leak” in your home but instead in your yard. If you notice sudden, muddy patches of dirt and grass, a pipe underneath may be leaking into the surrounding area.

How complicated is repairing or replacing a sewer line?

It depends. Mainstream will send one of our team members to assess the situation and determine the best course of action.

Depending on where the leak is and the core issue with the sewer line, it may take three to five days to repair or replace.

We’ll work with you on a timeline to ensure this issue is fixed as timely as possible.

So happy with the service and professionalism

We had only requested an estimate to replace the sewer line. Steve not only looked at the line, he cleared a clog and set us up with future maintenance!


Our home is 66 years young and it was time to replace the original water lines and sewer lines. I was amazed that they were able to streamline, fix old plumbing mistakes and make our entire water system user friendly. Thank you Cody, Donovan and the third guy that I can't remember his name. They were all professional, polite and knowledgeable.

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.
