Backflow Testing
Backflow prevention devices keep irrigation water from contaminating your drinking water. Our certified backflow testing ensures your system is safe, compliant, and functioning properly. We provide quick, affordable testing and handle all the paperwork if required by your municipality.
Certified Backflow Testing to Protect Your Water Supply
Annual certified testing of backflow prevention devices is required by Section 19-13-B38a of the Regulations of Connecticut State Agencies and by your water company. We can help.
Why It Matters
Your irrigation system keeps your lawn green and healthy — but without proper protection, it can also contaminate your drinking water. Chemicals, fertilizers, and microbes from your yard can flow back into your home’s plumbing or even the public water supply during low-pressure conditions.
This can happen when:
- Fire hydrants are in use
- Water main breaks occur

backflow prevention device
To prevent this, a backflow prevention device is installed on your irrigation system, as required by the Connecticut Department of Public Health (DPH). For your safety (and your neighbors’), the DPH requires annual inspections to ensure the device is working properly.
