Frequently Asked Questions About Backflow Testing

What is backflow, and why is it dangerous?

Backflow happens when water reverses direction in a plumbing system. This reversal can allow contaminants such as chemicals, bacteria, or debris to enter the clean water supply. Proper prevention and testing help keep household drinking water safe.

Can minor issues be fixed during backflow testing?

Small problems, such as worn components or minor valve issues, can often be addressed during the same visit. Handling these concerns right away helps keep the system operating correctly. Early fixes also reduce the likelihood of larger repairs later.

What happens if my backflow system fails inspection?

If a system does not pass inspection, GEM technicians explain the issue and outline the steps needed to correct it. Recommended repairs or adjustments help bring the system back into compliance with local requirements. Once the issue is resolved, we can perform a follow-up test to confirm the system is operating properly.

How long does a backflow test usually take?

Many backflow inspections take less than an hour to complete. The exact timing depends on the size and accessibility of the system being tested. GEM technicians perform each step carefully to ensure accurate results.

How often should backflow testing be performed?

Backflow prevention systems are typically tested once per year. Annual inspections help confirm the device is working properly and meeting local safety requirements. Regular testing also helps identify wear or performance issues before they become larger problems.
