Preparing Your Water Heater for Installation
Before you start installing your recirculating pump, you need to prepare your water heater. This step is very important for a safe and smooth installation. Here’s what you need to do:
Shutting Off the Water Supply
- Turn off the water heater. For electric heaters, find the circuit breaker and switch it off. For gas heaters, turn off the gas supply valve.

- Connect the faucet supply tubes to the check valve. Make sure the hot water tube goes to the hot side and the cold water tube goes to the cold side.
- Run new water supply tubes from the check valve to the shut-off valves. Measure and cut the tubes to the right length.
- Mount the check valve securely to the wall using screws from the kit.
Testing the Check Valve for Proper Function
After installing the check valve, it’s time to test it:
- Turn the water back on and check for leaks.
