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.

Maintenance

Routine inspections and maintenance keep your system compliant and efficient year-round. Our technicians clean components, and replace worn parts before they lead to failure. We also provide convenient scheduling reminders, so you never miss an annual inspection required by local codes.

I needed a repeat for a light fixture install that went bad and took out power to my garage. Mike and Josh showed up first thing in the morning and immediately spotted the issue and restored power, installed the light fixtures and also replaced a transformer for a video doorbell. All the work was clearly explained and done quickly and cleanly. So, I was very pleased with the experience and the electricians and will be calling Landry again next time I need some work done!

Mr. Humphrey sorted out the problem quickly - out of propane. So, I got on to the dealer quickly. I was glad the tankless water heater unit was fine. The unit was less than a year old so still under warranty.
