The overview

What it is, and why it matters.

A backflow preventer keeps irrigation water, which can carry fertilizer, pesticides and soil, from flowing back into the drinking water supply. Local codes require one on irrigation systems, and the type depends on the utility and the system. We install the approved device at the right height and location, with shutoffs, and pressure-test it.

In Nashville and surrounding utilities, requirements differ, so we confirm which device and testing schedule your water provider requires. We also protect the device from freezing with an insulated cover, and we leave you the test report your utility may ask for.
