- Product Description
The Hydraulic Backup Valve provides an entirely mechanical, self-contained, automatic water backup solution. It does not require any electricity, is completely waterproof, can be mounted in any position, and is not affected by sunlight. When rainwater is no longer available the valve will switch from rainwater to municipal water automatically by detecting the pressure drop.
