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.

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.

Technicians Randy Kyle and Richard Kyle were amazing. They were very knowledgeable and very professional. They explained every aspect of the service they provided. I felt very confident the job was done well. I did feel the cost was high but the customer service and respectful concerns from the technicians were a great asset to my decision to have the job completed.

I had two service techs come out on Wednesday to diagnose a problem with our heating system. They were very thorough and determined that it was some dust build up in the system. On Friday a new tech came out and cleaned the system. I thought for about 3 hours total of labor they were priced very reasonably and I would definitely be calling for services in the future.

It was a pleasure working with Landry mechanical and their crew. Nick the lead in the job was very knowledgeable and explained the install thoroughly. The install of water heaters and whole house water filtration was phenomenally done. The guys installing truly care about their quality of work and the install as a whole. Crispy clean product.

My experience was great. Team that arrived was awesome. I have just two opportunities to discus. The first was I was given a time window of between 8-12pm arrival. The team did not show up till after 3pm. This left me unable to do other tasks outside of my home. To be clear they communicated very well throughout and I appreciate this. But as stated by them they were running behind from other appointments. I would like to believe that the 8-12pm time frame built in extended work events. I’m happy I was able to wait the time for service but it was way too long in my opinion. The second thing was the cost of repair. I agreed to the cost but what I would have liked was an actual break down of parts, labor, use of tools to properly make sense of cost not just the service and the cost. Other than those two suggestions I am very happy with service, knowledgeable, professionalism. I will call them again for service.

All of the people who worked on the job were excellent, they communicated very well about their progress, and the new system works really well. Shout out to Donald for the electric upgrade, he even organized and hung up my networking equipment that was near the panel. A+

Efficient and professional service done in a timely manner. Mike and Anthoney were knowledgeable and efficient. They listened to my questions and explained things in terms I could understand. We were very pleased by their attention to detail and they went above and beyond expectations in fixing several small issues before things got to be larger issues.
