Check that the device is doing its job
Backflow testing checks the operation of the prevention device. Its internal parts must respond correctly to keep reverse flow from reaching the drinking water supply. A device can have worn parts or debris inside without showing an obvious problem during everyday water use.
Our certified tester checks the device and explains the findings. If something needs attention, we explain what the result means and the next step for that device. Testing gives you a clear picture of how the backflow preventer is working.
Protect the clean water side of the plumbing
Backflow can happen where a clean water line connects to equipment or another water source. A drop in supply pressure or greater pressure on the other side can reverse the normal direction of flow. The right prevention arrangement separates that risk from the clean water supply.
We discuss backflow prevention in the context of your building and the plumbing it serves. The type of connection matters. An existing device, a change to the plumbing and a routine testing request each need the right attention.
Take care of a testing notice
If your water supplier or another authority sent a testing notice, keep it handy when scheduling. The device information, due date and any supplied form help us match the visit to the request. We handle residential, commercial and restaurant plumbing.
Common questions
Is your backflow tester certified?
Yes. We have a certified backflow tester who handles this service.
How often should a backflow device be tested?
Follow the testing schedule required for your property and device. A notice from your water supplier is a useful starting point.
Does a device need testing if there is no visible leak?
Yes, when testing is due. The parts that prevent reverse flow can need attention even when the outside looks fine.
