How to Know if Your Home Needs a New Sewer Line

It’s always best to pay close attention to the operation of your sewer line. The closer you look, the more likely you’ll detect signs of impending failure before a critical malfunction occurs.

Common signs of problems include:

  • Slow drainage from sinks, toilets, and showers
  • Frequent clogs
  • Noxious odors coming from drains
  • Gurgling sounds after showers or flushes

These issues can indicate significant problems that are preventing proper wastewater removal.

Sewer Line Replacement

Our licensed and insured plumbers can perform traditional trench and trenchless sewer line replacement. We’ll help you determine which is best for you based on the condition of your pipe and other factors. In all cases, our goal is to complete the process with as minimal disruption to landscaping and hardscaping as possible.

What is a Septic-to-Sewer Conversion?

Septic-to-sewer conversions simply change the way wastewater is managed on your property. Rather than treating the sewage in a septic tank and depositing it within a leach field, the wastewater from your sinks, showers, toilets, etc., will flow into the municipal sewer line. 

There are many benefits to converting to a sewer system. These include more convenient wastewater management and reliability, and if the house is in a rural area that’s being urbanized, it preemptively prepares your property for future mandates.

We’re Seattle’s Septic-to-Sewer Experts

Many homeowners in the area are eager to convert their aging septic systems to sewer systems. We can help you make the switch. When your septic system no longer provides reliable performance or suffers a critical malfunction, we’ll complete the steps necessary for conversion. We’ll also ensure the project is properly permitted.

Why We Recommend Perma-Liner for Seattle Homeowners

Perma-liner is a cured-in-place piping (CIPP) solution. It’s a resin-saturated tube made of polyester, fiberglass cloth, or felt that’s inserted into the pipe. Once the liner is in place, a UV light is passed through the pipe, which cures the liner and bonds it to the interior of the pipe. 

This is a fast, safe, and effective solution that will restore the integrity of your sewer line. It won’t diminish drainage and will provide a permanent, reliable solution to a wide range of problems.

Septic-to-Sewer FAQs


When providing a quote for septic-to-sewer conversions, we consider the size of the property, location, type of plumbing, required excavation, and other factors.

Actually, the opposite. Septic systems use more water than sewer systems, so you may notice a significant decrease in water consumption.

Most home buyers prefer homes that are connected to the municipal sewer line. Thus, it’s likely that converting your home will lead to an increase in value for your property.

Abel and Daniel were amazing! They were there the next day to assess the water heater. They came with a big truck of supplies and were able to install what we needed the same day.

Garrett and Stephen came out and quickly and professionally replaced our 70-year-old sewer plumbing after it cracked. They worked super hard and ensured we had working plumbing each night and through the weekend. They finished and cleaned up and I would highly recommend them.

Chris was a very professional, knowledgeable, polite and patient plumber. They said he'd be here within the hour, he was here in 20 minutes. Pieces were missing from our brand new toilet to be installed, he was willing to take his lunch and allow us the time to run to Home Depot to exchange the toilet. Once we had all the parts, he installed it…
