Backflow Testing and Inspection Services

With backflow testing, a certified plumber can verify that your water is entering your plumbing system as it should, that there are no leaks, and that all parts of your backflow preventer are in working order. This should be done at least once a year, and depending on your company, there may be a legal requirement for it.

Frequently Asked Questions

How often should I have my backflow preventer tested?

How often you should test your backflow preventer depends, but at least once a year is a good rule of thumb. Depending on what kind of business you operate, your municipality may have legal requirements on how often you need backflow testing services. Regular maintenance is the best way to prevent unexpected repairs.

Do I need a backflow prevention device?

If there’s a chance wastewater and potable water can interact – like in a closed plumbing system – then you need a backflow prevention device. Depending on your company, you may need one to meet local code and legally operate.

Why is a backflow preventer important?

A backflow preventer is important because it keeps water moving in one direction, meaning wastewater won’t back up and mix with water in the main line or come back into your water supply. Potable water contamination can cause illness for everyone consuming your water.

How do I know if I'm getting backflow?

You won’t always immediately notice your backflow preventer is broken. Here are a few signs to look out for:

  • You have leaks, but there’s no obvious cause for them.
  • Check valves make unusual noises.
  • Your water is discolored, has a bad odor, or tastes strange.
  • You have bad water pressure.
  • Your water drains slowly.
  • Your staff and customers are becoming physically ill, and your water is the only common connection between them.
