Backflow Testing & Prevention
Protect your drinking water with certified backflow testing, fast compliance reporting, and professional service when safety is at risk.
Fast backflow response for water safety and compliance issues.
Keep Water Safe and Systems Compliant
Backflow devices protect potable water from contamination caused by pressure changes. We handle testing, repairs, and compliance reporting for homes, businesses, and multi-unit properties.
Signs You Need Backflow Testing Now
Compliance letter from the water authority
CriticalPWSA and most municipal utilities send annual testing notices. Miss the deadline and the fines add up — and some authorities will turn off the meter.
Discolored water after pressure loss
UrgentIf a water main break on your street pulls pressure in reverse, a failed backflow device can let contaminated water back into the potable supply. Rusty or cloudy water after pressure events is a warning sign.
Device visibly leaking or dripping
UrgentAn RPZ assembly dumping water at the relief valve means it's doing its job — but also that it needs service. Don't ignore it.
New addition, remodel, or equipment
Plan aheadAdding irrigation, a boiler, a commercial dishwasher, or a lab sink can create new backflow exposure. A pre-install assessment saves inspection headaches later.
How Our Backflow Testing Works
Locate the device and verify the type
RPZ, DCV, PVB, or atmospheric vacuum breaker — the test protocol is different for each. We note serial, location, and last-test history.
Run the certified test
Calibrated test kit, the water authority's prescribed procedure. Takes 15-30 minutes per device depending on type.
Submit the paperwork
We fill out the test report and submit it directly to the water authority on your behalf. You get a copy for your records.
Repair on the spot if it fails
Our trucks carry the common rebuild kits and whole replacement assemblies. 9 out of 10 failed devices are back in service before we leave.
Where Backflow Protection Matters Most
Restaurants and food service
Commercial dishwashers, carbonated-beverage equipment, and mop sinks all require testable backflow protection. We test and service the whole setup.
Medical and dental offices
Autoclaves, dental chairs, and lab sinks are high-hazard connections. Annual RPZ testing is standard — we're on rotation with several Southpointe and Mt. Lebanon medical buildings.
Irrigation and fire-suppression systems
Lawn irrigation needs a PVB or RPZ at the point of connection. Fire-sprinkler service lines require DCV or RPZ depending on hazard classification.
Home additions with boilers or cisterns
A new boiler or rainwater cistern can introduce backflow exposure in a residential setting. We install and certify appropriate devices where the code requires.
Backflow Testing FAQs
How often do I have to test in the Pittsburgh area?
PWSA and most surrounding municipalities require annual testing on most commercial and high-hazard residential installations. Some devices on lower-hazard applications may be on a 3-year cycle. We verify the requirement for your specific property when we show up.
What happens if my backflow device fails the test?
We carry common RPZ and DCV rebuild kits on the truck plus whole-assembly replacements for the most common sizes. 9 times out of 10 we repair or swap it on the same visit, re-test, and submit the passing report before we leave.
Do you handle the paperwork with the water authority?
Yes. We complete the test report and submit it directly. You get a copy for your records and an email reminder a month before next year's test is due.
