  • A backflow preventer is a specialized plumbing device designed to stop contaminated water from flowing backward into your home’s clean water supply. Backflow can occur due to sudden changes in water pressure—caused by events like a burst pipe, firefighting efforts, or major water main breaks. Without a backflow prevention system in place, harmful substances like pesticides, bacteria, or chemicals could infiltrate your drinking water, posing serious health risks.

    This is why many municipalities, including those in Knoxville and the surrounding areas, require annual backflow testing and the installation of approved backflow prevention assemblies.

Expert Backflow Preventer Installation

When it comes to installing a backflow preventer, precision and expertise are essential. At Mr. Rooter Plumbing of Knoxville, we understand local plumbing regulations and follow industry best practices to ensure every installation is performed correctly the first time. Our licensed plumbers will assess your home’s plumbing layout and recommend the best location and type of device to match your system's needs.

We install a range of backflow prevention devices, including:

  • Pressure Vacuum Breakers (PVB)
  • Double Check Valve Assemblies (DCVA)
  • Reduced Pressure Zone Assemblies (RPZ)
  • Atmospheric Vacuum Breakers (AVB)

Our team ensures proper installation and system integration, helping you meet local codes and maintain clean, safe drinking water.

Backflow Testing and Certification

In many parts of Tennessee, including Knoxville, homeowners are required to have their backflow preventer tested annually by a certified professional. These tests are not just about compliance—they are vital for confirming that your device is functioning correctly.

Mr. Rooter Plumbing offers certified backflow testing and will provide documentation to meet your municipality’s requirements. During testing, we will:

  • Inspect all components of your backflow device
  • Measure pressure levels
  • Identify signs of wear, leaks, or valve failure
  • Submit required reports to local water authorities

If we detect any issues, we’ll walk you through your repair or replacement options so you can make informed decisions.

Prompt and Professional Repairs

If your backflow preventer is leaking, producing low water pressure, or has failed a test, you need reliable repairs—and fast. Our technicians are trained to work on all makes and models of backflow assemblies. We carry the tools and replacement parts needed to restore functionality quickly and correctly, minimizing the risk of contamination and keeping you compliant with local codes.

Common repair services include:

  • Replacing worn-out check valves or seals
  • Fixing leaks and corrosion
  • Addressing water pressure irregularities

We’ll also verify that the new installation passes required tests and submit documentation to your water utility for compliance purposes.
