Mains water Back-up Box

Description

The Mains water Back-up Box is needed in times of drought as part of your rainwater harvesting system. Every system needs a mains water backup to keep  appliances going when there is not enough rainwater stored in your tank.

The simplest way is with a float switch and solenoid valve – the float switch detects when the rainwater storage tank is empty and opens the electrically-actuated solenoid valve allowing mains water to flow into the bottom of the tank. W
