Submersible pumps

How to choose a submersible pump

Start with the job the pump has to do, then what's in the water it will move.

• Why a submersible pump?

  A submersible pump sits in the water it moves, so it runs quietly and doesn't need priming. In a rainwater tank that means no pump noise near the house.

• Supplying the house from a tank

  Choose a bare pump, a kit with a pressure controller, or a system that switches to mains water when the tank runs low. Tell us how many bathrooms and taps you have and we'll size it.

• Match the pump to what's in the water

  Drainage and dewatering pumps empty sumps, cellars, pits and flooded areas. For waste, vortex pumps handle grey water with small solids, single-channel pumps suit effluent, and cutter and grinder pumps break up sewage so it can go through a smaller pipe.

• Automatic or manual

  On our drainage pumps, models with an A in the code have an automatic float switch and M models are manual. Each product page lists the maker's flow, head and warranty. Tell us what the pump needs to do and we'll point you to the right one.
