How to Hook Up Irrigation Pumps

If you want to ensure that a garden or another part of a landscape that needs to stay moist gets regular watering, you may want to consider installing an irrigation system. An irrigation system is an in-ground automated water sprinkler that generally works on a timer to supply water regularly to an entire section of a yard, preventing the need for manual watering. The heart of an irrigation system is the irrigation pump. The pump and the timer are linked by a go-between called a pump start relay.

Pump start relay
Wire nuts

Instructions

- 1
  Strip back the two wires on a sprinkler system timer by about 1/2 inch with wire strippers. Strip the timer wires on the pump start relay back by 1/2 inch as well.
- 2
  Match the two wires from the timer up with the two wires on the pump start relay by color. Twist the exposed ends of the wires of the matching colors together. Wires on the timer and pump start relay are generally white and red.
- 3
  Screw a wire nut onto the ends of the two white wires twisted together.
- 4
  Strip the ends of the pump wires on the pump start relay to ½ inch and the wires on the irrigation pump to ½ inch. Twist the wires of corresponding color together as you did between the pump start relay and the timer. Cap each set of wires with a wire nut.
