Renton Backflow Testing & Repair

Keeping Your Water Clean & Safe

Did you know that there is a possibility that your potable water might be contaminated? Although your home plumbing designed to let water flow in a single direction, pressure changes inside the pipelines can cause the water to reverse direction or cause a backflow. Both residential and commercial properties are required by law to install backflow prevention devices to their plumbing to avoid water contamination. However, this is not enough—it is also a must that these devices are tested regularly.

The Plumbing Joint is Renton’s premier provider of top-quality plumbing services including backflow testing and repair. Our licensed, trained, and certified plumbers are experts in providing comprehensive inspections of backflow devices to determine their current condition. Should we find any problems, our plumbing team can also fix it for you promptly and efficiently.
