What Is Backflow Prevention?

Backflow prevention protects your home’s water supply by stopping dirty or contaminated water from flowing backward into clean lines. When water pressure changes unexpectedly (such as during a pipe burst or heavy usage) it can cause pollutants to enter your drinking water. A backflow preventer keeps water moving in the right direction, protecting your family’s health and ensuring your system remains compliant with safety codes.

Backflow Services We Offer

At Landry Mechanical, we provide a complete selection of services designed to protect your water supply and maintain consistent system performance. Our technicians handle everything from new installations to annual inspections with precision and professionalism. With certified training and a commitment to quality, we make sure your backflow prevention system continues to safeguard your home or business year after year.

Backflow Installation

We install backflow prevention devices for both residential and commercial properties, ensuring clean water remains separate from potential contaminants. Each installation is customized to your property’s layout, water pressure, and usage needs. Our team follows all local and state regulations, providing a system that’s both compliant and built to last.

Backflow Repair and Replacement

If a test shows damage, wear, or improper valve function, our technicians provide expert repair or replacement. We use high-quality parts and industry-approved methods to restore your device’s performance and reliability. Whether it’s a small component repair or a full replacement, we ensure your water system remains protected from contamination risks.

Professional. Outstanding service. My wife and are were in Florida and we had an issue with a freezing pipe outside the house creating a hockey rink in our driveway. Our kids called us to alert us and Landry came right out. Diagnosed the issue and had it fixed right away. The tech was fast, efficient and professional. Could not be more happy.

Jorge Gonzales from Landry arrived on time today to check out the faucet in my shower. I was not getting enough hot water but all other faucets were fine. He quickly found that the rubber gasket on the cartridge had deteriorated, replaced it, and left my shower as clean as he found it. Jorge was courteous, friendly and professional. I would not hesitate to have him come and do additional work for me. Landry is lucky to have him!

I cannot say enough how happy I am for choosing Landry. Sam Reynolds and Josh Clough came out one day to look at an electrical repair, gave me an estimate then came back the next day to do the repair. Sam and Josh worked in 15 degrees weather, did a great job, frendly and accommodating, I would recommend them to anyone. Thank Mike Massauro
