Your local government or water provider may notify you to report the results of your tests.

The necessity of backflow testing services begs the question: what is it? 

One plumbing service is backflow testing, which involves measuring the pressure inside your backflow preventer to make sure it’s working properly. Untreated or polluted water might be redirected into your potable water supply in the event of backflow. The water you drink and bathe must be safe and sterile, which is why testing is done.

What is Backflow?

Potable water and wastewater are brought in and removed by separate pipelines in a home’s water system. Backflow occurs when this water system’s pressure drops. This drop in water pressure causes the improper routing of wastewater—whether from a toilet or a hose—from the waste pipes out of the clean water pipes. 

A backflow incident can occur in several common scenarios: 

  • Excessive use of water from a public source in the area (for instance, a fire hydrant pulled during a fire) 
  • Harm to the pipes that carry water 
  • Failures of pumps 

More specifically, you should be aware that the entire county’s water supply could be affected by only one backflow event, not only you and your neighbourhood. Consequently, many individuals could experience troubles due to backflow issues. Nevertheless, measures can be taken to prevent water system contamination by using backflow prevention devices and processes. 

Backflow: Why Is It Dangerous?

The introduction of harmful contaminants into your water system is a direct result of backflow. If you have a garden hose attached to a container of toxic weed killer, for instance, and the water flows backwards, the chemicals could be reintroduced into the water system.

Valves are automatically opened and closed by mechanically powered backflow preventers. This technology ensures that none of your effluent could end up in the water supply. Problems get messy when backflow preventers don’t work. 

Sprinklers and irrigation systems in homes and businesses must also undergo annual testing. Your gadget must undergo annual testing in many communities.
