Backflow testing helps ensure contaminants do not enter your drinking water supply through a failed or malfunctioning backflow prevention device. If your property has an irrigation system, sprinkler system, boiler feed, or another cross-connection, routine testing may be required to help protect water quality and maintain compliance with local requirements.

Built on integrity, driven by family values, DrainGo Plumbing & Septic Services of Alabama provides professional backflow testing and prevention services for homeowners and property owners throughout Central Alabama. Schedule your service today to help keep your water system protected.

What Backflow Testing and Prevention Includes

Backflow Prevention Device Testing

We test your backflow prevention assembly to verify that it is operating correctly and protecting the drinking water supply from contamination caused by reverse water flow.

Cross-Connection Evaluation

Our technicians inspect the system for potential cross-connections that could allow pollutants, chemicals, or non-potable water to enter the clean water supply.

Compliance Verification

Many irrigation systems, commercial properties, and other plumbing systems require routine testing. We help confirm that your device meets applicable testing and compliance requirements.

Backflow Preventer Repairs

If a device does not pass inspection, we can identify the cause of the failure and recommend the appropriate repair to restore proper protection.

Device Replacement Services

When repairs are no longer practical or cost-effective, we can replace the backflow prevention assembly with a properly sized device for your system.

Testing Documentation and Reporting

After testing is complete, we provide the necessary documentation and reporting required for many residential, commercial, and irrigation system testing programs.

Draingo is the way to go!!!! We used Draingo last year in March 2025 after AHS sent their #1 company K&S Plumbing (who always refuses to work with the client) to fix the repairs that AHS stated that we weren't covered for. Long story short. Draingo came and determined that we were covered, repaired it and we were good.
However, recently the PRV they replaced went bad again this year. Come to find out the city of Calera_AL has too much pressure coming into the subdivision. My home is receiving 140 psi!!! Way too much. Logan from Draingo is the best! He came out and and told us exactly what we needed. He put the dual PRV on set our tank temperature and no leaks as of yet. This took place on 7/24/26. Thank you Logan and thank you Draingo!!!

Even though we were David's last stop of the day and he had to drive all the way from Mccalla to Chelsea at 5:30pm, he was smiling and engaging and got right into our issue, and he stayed until the issue was resolved and everything was cleaned up and put back as it was. David was a pleasure to work with, and he has probably now spoiled me on plumbers.
