Yes, we can address slab leaks, a common issue in Riverside's soil conditions. While primarily focused on backflow, our expertise in plumbing repair allows us to locate and fix these leaks. It's important because undetected slab leaks can lower water pressure, potentially causing backflow preventers to malfunction or fail their annual test. We ensure your entire system, from the pipe up, is secure.

Our installation or replacement service is handled start-to-finish by our certified technicians. We assess your property's specific needs, obtain any necessary permits, and install a compliant assembly correctly the first time. We're licensed (#1109590) and carry a limited inventory, which often allows us to schedule installations quickly for Riverside County residents and businesses, followed by the required initial test.
