A water booster pump is essential to boosting up water pressure and therefore increasing water flow to certain areas of the home. This is very helpful when you have a swimming pool, a fountain or small pond. Installing one at a home requires wiring it to the electrical supply.

Step 1 – Mount the Controller Box
Find a suitable location for the controller box to be mounted. The location should be away from direct sunlight and excessive moisture. It should also be as close as possible to the water tank. Screw the box to the wall surface.
Step 2 – Run the Cables
Check local codes to determine which type of cables to use. Determine if the local code suggests a specific type of conduit as well. Run a three-wire cable from the breaker panel to the location of the switch. Plan a path for the wire in the best way possible. Run it upwards to the ceiling, then on the edges of the ceiling to the location of the pump’s pressure switch. Run another cable from the switch to the location of the controller box. Be sure to cover the wires in conduit as per instructions from the local wiring codes.
Step 3 – Wire the Switch
Loosen any screws on the pressure switch cover. Remove the cover and determine where to wire the cable. Use the manufacturer’s manual to determine the correct wiring diagram. Using a utility knife, remove at least 2 inches of sheathing from the wiring cable to expose the color-coded wires. Strip half an inch off the black and white wires using a wire stripper.
Connect the black and white wires to the corresponding slots on the switch. Connect the ground wire to the ground screw. Do the same with the cable that connects the switch to the controller box. Double check all connections before putting the cover back on. Tighten the screws.
Step 4 – Wire the Controller Box
Remove the sheathing from the cable in the same fashion as that of the other end of the cable connected to the switch. Strip the wires as well. Remove the screws on the cover and pull it out of the box. Determine where the wires go into and secure the connections following correct color coding. Be sure to connect the ground wire to a ground screw or a bare metal in the controller.
Step 5 – Connect the Water Booster Pump to the Power Supply
Go back the breaker panel, remove the cover and turn the main switch off to avoid electrocution. Remove at least 6 inches of sheathing from the cable and strip the colored wires half an inch. Insert the cable through a knockout and clamp it tight. Connect the neutral wire to the neutral bar and the black wire to the screw on the circuit breaker. Test the connection by turning on the power supply and the pump. Put the cover back on the panel.
