Backflow may occur due to pressure changes caused by water main breaks or excessive water use. When this happens, wastewater can move into supply lines instead of the sewage system. Backflow may also occur when contaminated water from soil siphons into supply lines. Fortunately, backflow devices can block impurities from entering your freshwater. Here's how to tell when you need backflow testing or repairs to ensure the device's efficiency. 

4 Signs You Need Backflow Testing or Repairs

1. Water Pressure Changes

Plumbing pressure can change when a pipe freezes and bursts. This often causes weak flow from some faucets and stronger water pressure from other fixtures. A plumber can test your backflow device by checking the valves to ensure they open when they sense reverse water pressure. 

2. Discolored Water 

If the water flowing from faucets and fixtures turns brown, gray, or black, this often indicates the failure of your backflow preventer. The discoloration occurs due to the presence of contaminants such as soil, fertilizer, or raw sewage. The water may also have an unpleasant taste and odor. A plumbing team can replace the device with one that has functional valves and seals that provide a dependable barrier against impurities. 

3. Slow Drains

Clogs in wastewater pipes or your septic tank can cause raw sewage to flow back into floor, sink, and tub drains. In addition to causing property damages, sewage backups can change the pressure in plumbing pipes that puts fresh water cross-connections at risk of contamination. A plumber should test your preventer device to ensure it doesn't allow sewage into your fresh water and cause illness.

4. Leaks

If you notice water dripping or pooling near your irrigation system's shutoff valve, this may indicate that the backflow device has failed. A plumbing technician can check the internal springs, seals, and mechanical components and replace any worn parts to ensure the device prevents fertilizers and pesticides from siphoning into your water supply.
