Backflow Preventer Replacement: Signs You Need One

master plumbing backflow preventer

Water can flow through this device into schools, buildings, and residential properties.

A backflow preventer keeps our water supplies clean, fresh, and sanitary. However, this remarkable device can experience wear and tear and other issues like any device. Would you know if your backflow preventer needed a replacement? Here are some signs. 

What is a Backflow Preventer?

It’d be impossible to know the difference between a fresh, clean water supply and one contaminated with backflow. The different types of backflow preventers include: 

  • Double check valves
  • Reduced pressure zones
  • Pressure vacuum breakers 

While they all differ slightly, these devices guarantee a one-way water flow. Water can flow through this device into schools, buildings, and residential properties. Once that water makes it through the system, the check valves close, preventing liquids from moving backward into the potable (safe to drink) water supply. Therefore, it prevents dirt, bacteria, and other harmful contaminants from entering an otherwise sanitary water supply. 

The Signs of Damaged Backflow Preventer 

  • Water leaks: A water leak is common in many devices. A water leak might happen because of an old, shifted, or cracked rubber seal. You might attempt to replace the rubber parts yourself. However, you won’t know if you replaced them correctly without a backflow testing kit. Additionally, a leak could lead to corroded valves. Also, if any part of the backflow preventer is only a hair-off, you could cause more damage to your system and the public water supply. Plus, most water authorities require that backflow systems pass an inspection by a certified tester after requires and during your annual testing. 
  • Water Pressure Changes: Water pressure changes could be a sign of trouble. The opening points of valves could have defects, especially if your area has poor water quality. The backflow preventer or filter might be clogged with debris or damaged by a small rock. 
  • Discolored Water: Discolored and cloudy water that tastes terrible means something is awry. A backflow device in your area might have stopped working, and your water supply might have contaminants. Even if your device works correctly, a neighbor’s failing device could lead to fertilizer, stagnant water, and soap in your water supply. 
  • Slow Drainage: If you notice any poor drainage in your sinks, showers, or other water features, there might be a clog or buildup affecting your device. A backflow could also already be in your water supply. If so, it’s best to call a professional plumbing company.
