Estimate the flow and pressure requirements of an irrigation system by calculating the water flow in gallons-per-hour and attaching a pressure gauge to the faucet or pipe the pump will attach to. Select a pump rated for the flow and pressure needs of the existing irrigation system. Connect the pump to the system ensuring the water supply connects to the inlet valve and the outlet valve connects to the irrigation system. Use plumbers tape to cover the threads of the connectors to prevent leaks.

Mount the pump relay controller in a nearby location protected from direct sunlight. Connect the controller to the pump before connecting the relay and pump to the electrical system. Restore water flow to the irrigation system before activating the pump and controller. If there is no compatible electrical outlet for the pump and controller, one may need to be installed. Turn off electrical power at the breaker before installing or wiring any components.
