Frequently Asked Questions

In-House Excavation Services

We are proud to provide Spokane, WA residents with a one-stop shop for all their plumbing needs. We have streamlined the excavation process by building a crew of in-house excavation specialists. Communication between our departments is seamless, allowing us to keep you in the loop from start to finish.

We also understand that having third-party “hired hands” in your backyard can be unnerving – that’s why we only send our own employees to your home. When you choose Mainstream, you can trust that every on-site employee was hired based on our high recruitment standards.

Cured-In-Place Pipe Repair

If we are able to detect your sewer problem before major damage occurs, trenchless sewer line repair could be the way forward!

A classic example is cured-in-place pipe (CIPP) sewer repair. This is a trenchless restoration method which involves inserting a seamless, jointless, and root-resistant lining inside an existing sewer line.

The lining, which contains resin, is exposed to a curing element which allows it to adhere to the inner walls of your sewer line. Voila! Once fully cured, you have a brand new pipeline.

It is worth noting that CIPP is EPA Certified and has no negative impact on the environment.

Pipe Bursting Trenchless Sewer Line Replacement

If, however, our analysis renders CIPP sewer repair impossible, there’s no need to despair. We have other non-invasive procedures at our disposal. Pipe bursting is a great alternative if portions of your sewer line have collapsed or are otherwise unable to accept a new lining.

This trenchless sewer replacement method is as satisfying and simple as its name suggests. Two holes are dug at both ends of the line. A steel expander head is then dragged through the existing pipe. Its slightly larger diameter allows it to shatter the old pipe and push its pieces into the soil as it’s traveling. A new replacement pipe follows closely behind and takes the spot of the old. The new sewer line is then simply reconnected at both ends and is ready for use.

Our state of the art equipment can pull pipe through the ground at a maximum working force of 60,000 psi.

Of course we can! Because we are so excellent at laying pipe across Spokane, you’ll want our opinion about your home too.

Yes, a broken sewer line can often be repaired without extensive excavation through trenchless sewer repair methods. Trenchless sewer repair allows for the rehabilitation or replacement of damaged sewer pipes without the need to dig up and remove the old pipeline. The process begins with a camera inspection of the pipes to assess the extent of the damage and determine the best repair options. There are two primary trenchless methods: pipe lining (Cured-in-Place Pipe – CIPP) and pipe bursting. Pipe lining involves inserting a resin-coated tube to create a new inner pipe, while pipe bursting fractures and replaces the old pipe. Trenchless methods offer benefits such as reduced disruption, faster repair times, and potential cost savings compared to traditional excavation and restoration. However, the applicability of these methods depends on the specific situation and the severity of the damage. While trenchless sewer repair may offer cost advantages and the longevity of resin pipes, it’s essential to note that it may not always be feasible in every scenario. To determine if your home’s pipes can benefit from quick and efficient trenchless repairs, trust the expertise of Mainstream Plumbing and Air’s professionals.

Protect Your Home with Lasting Sewer Line Replacements in Spokane

A damaged or aging sewer line isn’t something to ignore. It can cause slow drains, foul smells, soggy yards, and, in the worst cases, raw sewage backing up into your home. At Mainstream Electric, Heating, Cooling & Plumbing, we provide professional sewer line replacement services designed to restore peace of mind—and protect your home from further damage.

With over two decades of experience serving Spokane and Northern Idaho, we know how to handle even the toughest underground plumbing problems. Whether your home needs a full sewer line replacement or just a targeted solution, our team will explain your options clearly and complete the work with precision, care, and respect for your property.

Do You Need a Sewer Line Replacement?

Many homeowners don’t think about their sewer line until something goes wrong—and by then, it may be too late for a simple repair. Here are a few signs that your sewer line may need professional attention:

  • Frequent backups or slow drains throughout the house
  • Unpleasant odors coming from sinks, tubs, or the yard
  • Soggy patches in the lawn, even during dry weather
  • Gurgling sounds from plumbing fixtures
  • Noticeable dips, cracks, or sinkholes in your yard

While some of these issues may be resolved with a basic drain cleaning, recurring problems often point to a larger issue underground. That’s when a camera sewer line inspection can help. Our team uses advanced technology to inspect the inside of your pipes and pinpoint exactly what’s causing the problem.

Trenchless Sewer Line Replacement: Less Disruption, More Peace of Mind

In many cases, we’re able to offer trenchless sewer replacement, which allows us to replace your sewer line without digging up your entire yard. This innovative method uses small access points and specialized equipment to install a new pipe through the path of the old one—minimizing damage to your lawn, driveway, or landscaping.

It’s ideal for:

  • Homes with landscaping or concrete above the sewer line
  • Pipes damaged by roots, corrosion, or ground movement
  • Homeowners who want a quicker, less invasive solution
