Fixing Plumbing Issues Before The Tank

  • Broken, cracked, or collapsed pipes
  • Sewer camera inspections

🚫 What We Don’t Do:

  • Septic tank pumping or cleaning
  • Septic inspections or permitting

We don’t pump, inspect, or service septic tanks. Instead, our licensed plumbers specialize in diagnosing and fixing drainage and sewer line issues before the tank, helping septic homeowners across Renton, Tukwila, East Renton Highlands, and nearby communities.

Not Sure if It’s Plumbing or Septic? We’ll Find Out.

Before you call a septic company, let Harts inspect your plumbing. We’ll run a sewer camera, evaluate your system, and give you an honest diagnosis. If it’s something we can fix, we’ll take care of it. If not, we’ll point you to the right septic provider.

What to Watch For

Plumbing Problems in Septic Homes:

Septic system homeowners often assume the worst, but not every drainage issue means your tank is full or failing. In many cases, the problem is in your indoor plumbing or sewer line.

Common signs of plumbing-related issues in septic-connected homes include:

  • Toilets that gurgle or bubble

  • Wastewater backing up into tubs or showers

  • Drainage problems after running the washer

  • Unpleasant odors coming from drains

  • Only one or two fixtures acting up

  • Consistently slow-draining sinks or showers

If you’re seeing these signs in your Renton home, it’s time to call Harts. We’ll determine if the problem is in your system or in your plumbing leading to the tank.
