Backflow Preventer Replacement & Concrete Restoration – Sarasota, FL
During a recent plumbing project in Sarasota, Florida in early April 2026, we were called out to replace a damaged backflow preventer located on a water service line beneath a concrete pad. To access the plumbing system, we carefully cut and removed the concrete slab to expose the underground piping and backflow assembly.
After exposing the water service line, we removed the damaged section of copper piping and installed new copper risers along with protective concrete sleeves. These sleeves help protect the copper piping from corrosion and damage when the concrete is poured back, which is an important step in under-slab plumbing repairs.
We then installed the new backflow preventer, secured all fittings, and pressure tested the system to ensure there were no leaks and that the water service line was operating properly. Once testing was complete, we repoured the concrete pad and restored the area.
To protect the new backflow assembly from accidental vehicle damage, we placed large protective boulders around the backflow preventer to act as a barrier and prevent future damage.
We began by cutting and breaking open the concrete slab to access the underground water service line and the backflow preventer assembly.
After the concrete was removed, we excavated the area and exposed the underground copper water service line so the damaged piping could be removed.
We installed new copper risers and protective sleeves to bring the piping up to grade and protect the lines before the concrete was repoured.
The new backflow preventer was installed and connected to the water service line to protect the clean water supply from contamination.
After pressure testing the system, we repoured and finished the concrete pad around the new plumbing and backflow assembly.
Large protective boulders were placed around the backflow preventer to prevent vehicles from hitting and damaging the assembly.
