We test backflow preventers on commercial properties — offices, restaurants, retail, and multi-unit buildings — and file the required certification with your local municipality. Missing your annual test window can mean fines or even a water service interruption, so we track your due date and get it done on time.

Watch for these

Who Needs Backflow Testing

Signs you need this

  • Any commercial property with a fire sprinkler system
  • Buildings with irrigation systems connected to municipal water
  • Properties with a boiler, chiller, or other cross-connection risk
  • A notice from your municipality flagging an overdue test
  • New backflow devices that haven't been certified since installation

Why it happens

Municipalities require annual backflow testing because a failed preventer creates a real risk of contaminated water siphoning back into the public supply — a risk that grows with every cross-connection a commercial building has, from irrigation to fire suppression to boiler makeup water. Certification isn't optional in most jurisdictions; it's a standing legal requirement tied to your water service.

Questions

Backflow Testing Questions, Answered

How often is commercial backflow testing required?
Most Pennsylvania municipalities require annual testing for commercial properties, though the exact requirement depends on your local water authority.
What happens if I miss my testing deadline?
Consequences vary by municipality but can include fines or, in some cases, a water service interruption until testing is completed.
Do you test all types of backflow preventers?
Yes — reduced pressure zone assemblies, double check valves, and pressure vacuum breakers, whatever type is installed on your property.
Can you track my testing due date for me?
Yes — once we've tested your devices, we keep track of your next due date and can reach out before it’s overdue.
What if a device fails the test?
We repair or replace the failed device and retest it, so you receive valid certification on file.
