Call Now (607) 302-4765If you got a notice from your water utility about backflow testing, or a home inspection flagged your irrigation system's backflow preventer, we test and certify the device to keep you compliant. This is different from most of what we do, it's about protecting the public water supply, not fixing a leak in your house.
What a Backflow Preventer Actually Does
A backflow preventer stops water from flowing backward into the public supply line, a real risk on any irrigation system, pool fill line, or commercial connection where water could potentially siphon back and carry fertilizer, chemicals, or other contaminants with it. Most utilities require an annual test to confirm the device is still working correctly.
Who Actually Needs This
Irrigation systems, commercial properties, and any connection with a cross-connection risk typically require an annual backflow test under local code. Some mortgage lenders and insurers also require it as part of a property transaction. If you're not sure whether your property needs it, we can check your specific setup and utility requirements.
What Testing Involves
We test the device under pressure to confirm both check valves are sealing correctly and the relief valve is functioning as designed. If it passes, we file the required certification with your water utility. If it fails, we repair or replace the device and retest before certifying it.
Choosing the Right Device
Different backflow preventer types suit different situations: a simple irrigation system typically needs a different device than a commercial property with a higher contamination risk. If you're installing a new device rather than testing an existing one, we size and select it based on your property's actual connection type and local code requirements, not a one-size-fits-all default.
Scheduling Your Annual Test
Most water utilities send a reminder notice when your annual test is due. We can also set up a standing reminder for you, so testing stays current without you needing to track the deadline yourself. Missing the window can mean a follow-up notice or, in some cases, water service restrictions until it's resolved.
Residential and Commercial Testing
We test devices on both residential irrigation systems and commercial properties, including multi-device sites that need every backflow preventer on the property tested and certified together. A commercial property with several devices benefits from having them all scheduled on the same visit rather than staggered separately.
What Affects the Price
What actually changes the cost of backflow testing:
- 1Whether the device passes on the first test or needs repair
- 2Device type and size
- 3Number of devices on a commercial property
- 4Whether a new backflow preventer needs to be installed

Frequently Asked Questions
If your property has an irrigation system, a pool fill line, or a commercial connection, most water utilities require it annually. We can check your specific requirement if you're not sure.
We repair or replace the device, then retest it before filing certification with your water utility. We won't certify a device that isn't actually working correctly.
A single-device test is usually a quick visit, typically under an hour. A commercial property with multiple devices takes longer.
Yes. Once a device passes, we file the required certification directly, so you don't have to track down and submit the paperwork yourself.
It's not something we'd recommend without a licensed plumber, since an incorrectly installed device can fail the exact test it's meant to pass and may not satisfy your utility's certification requirement.
Depending on your utility's rules, you can face a compliance notice or, in some cases, water service restrictions until testing is completed. It's a straightforward, quick visit that's worth keeping current rather than risking that.
It depends on the connection type. An irrigation system or certain commercial connections typically require one. We can check your specific property against local code.
