How to connect a booster pump and a pressure control switch to a rainwater tank

Connecting a booster pump and a pressure control switch is a cost-effective solution for delivering water from rainwater harvesting tanks to toilets, kitchen appliances or your garden hose. The DAB KPF 30/16M Peripheral Electric Pump is a compact and reliable centrifugal pump rated at 0.37kW, which pumps up to 30 litres of water per minute. The Tradepower Automatic Water Pump Control Switch maintains constant water pressure while you are using taps. It works by automating the starting and stopping operations of the water pump with regards to a drop in pressure.

While we use a DAB booster pump and a Tradepower pump controller in the below example, the principles remain the same for most booster pumps and pump controllers with pressure switches. Click here to see Recommended Booster Pumps and Controllers.

What you need to connect a pump controller to your water pump

How do you install a booster pump and a pressure control switch to a rainwater tank?

Step 1: Remove the valve

Remove the valve at the top of the pump and attach the pressure control switch to the pump.

Step 2: Detach the lids

Detach the lids of the pump and the controller using a screwdriver/ electric screwdriver.

Step 3: Carefully expose the wires

Using your 3-core cable, carefully cut 8cm off the top and expose the wires (+/- 1cm).

Step 4: Attach the wires to the corresponding units

  • Live = Brown
  • Neutral = Blue
  • Earth = Green

First make sure that the screws are loose so that the wires can fit tightly underneath, then tighten.

Step 5: Attach the other end of the 3 core cable to the pressure control switch

  • U = Brown
  • V = Blue
  • Earth = Green

Step 6: Attach the lids

Attach the lids back on the pump and the controller.

Step 7: Attach the tank connector 

Attach the tank connector - which consists of the ball valve and quick coupler - to the reducer connected to the bottom of the rainwater tank (screw it on).

Step 8: Attach the male coupler 

Attach the male coupler to the inlet side of the pump. This part comes attached to the ball valve in the kit.

Step 9: Attach the ball valve 

Attach the ball valve to the pump controller (screw it on).

Step 10: Attach the flexible hose

Attach the flexible hose from the tank connector to the pump.

You can then attach a standard garden hose to your pump, and drill your booster pump into the ground.

The pump will turn on automatically when opening the tap.
