Backflow testing helps ensure contaminants do not enter your drinking water supply through a failed or malfunctioning backflow prevention device.

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.

A bathroom drain had started backing up, so I called Draingo Plumbing and Septic Services of Alabama to have it checked. The plumber diagnosed the issue, cleared the blockage, and ran the water afterward to make sure everything was draining properly. I liked that the work was explained before getting started and that there was no pressure to add unnecessary services. The job was handled neatly, and the area was left clean afterward. Everything went smoothly, and the drain has been working normally since the visit.

Big thank you to Jay! He was prompt in arriving when we called about a water leak on a Saturday morning. Jay was great in explaining our options. He didn't just fixing the current problem but also identifying issues that would be causing this problem again if left unattended. He was able to get everything fixed up and so helpful. We will definitely be calling Jay at Draingo for our future plumbing needs!!
