What is a Backwater Valve and Why Does It Matter?

A backwater valve is a crucial plumbing device designed to prevent sewage backflow from entering your home.

It features a normally open gate that allows the free circulation of air and sewage flow. In the event of a sewer backup, the gate floats into a closed position to protect your home from backflow. Regular maintenance of your backwater valve ensures optimal performance and longevity.

Essential Backwater Valve Maintenance Steps

To guarantee your backwater valve functions correctly and to avoid costly damage, follow these maintenance steps:

Visual Inspection

  • Remove the cleanout plug located on the top of the valve.
  • Use a flashlight or a trouble light to properly see inside the valve body.
  • Check for debris build-up on the body, gate, and beneath the gate.


  • If you find debris build-up, you will need to flush the valve clean.
  • To flush the valve, use a garden hose to direct water into the valve body, focusing on areas with debris.
  • You can use a long-handled brush to help remove stubborn debris and ensure a thorough cleaning.
  • Continue to flush the valve until all debris is removed, and the water runs clear.

O-Ring Inspection

  • Locate the o-ring on the valve body; it is the part that the gate seals against when in the closed position.
  • Inspect the o-ring for wear, cracks, or damage.
  • If the o-ring is damaged, remove it and replace it with a new one, ensuring a snug and secure fit.

Float Maintenance

  • Locate the closed-cell polyethylene floats on both sides of the gate. These floats are protected from sewage contamination by the sidewalls of the gate and body.
  • Check the condition of the floats, looking for damage or signs of wear.
  • If necessary, replace the floats with new ones, ensuring they are properly secured and positioned.

By following these steps, homeowners can effectively maintain their backwater valve and ensure its proper functioning. Regular maintenance is crucial to prevent potential sewer backflow and protect your home from water damage.
