Connect a submersible pump correctly

Submersible pumps can be of great service for watering gardens, maintaining a pond or a drainage system. They are very easy to use and have a great effect. It is also easy to connect, but there are a few details that should be noted.

How to successfully connect a submersible pump

Submersible pumps (€ 27.34 on Amazon *) n are practical helpers for pumping up water - with their mostly electrically operated paddle wheel in an encapsulated housing, they can pump water down to very low levels. This is very useful in many areas of the house and garden, for example:

  • When using a cistern
  • When pumping out ponds or pools
  • Cellars flooded when draining
  • For the constant emptying of a drainage shaft

Apart from their great auxiliary effect - delivery rates between 8000 and 20.000 liters per hour could never be achieved with a bucket or watering can - submersible pumps are also very easy to operate. They are simply connected, drained into the medium and can practically get started.

The connection is actually done in two uncomplicated steps: as a rule, the pump only needs to be connected to a hose and to the power supply. However, there are a few small things to keep in mind.

Hose connection

There are of course different hoses, and above all they have different diameters. The choice of the hose diameter should be adapted to both the cleanliness of the water to be pumped and the desired flow rate and speed. A clear water pump for an aquarium, for example, only needs a thin hose, a dirty water pump that is supposed to pump out larger amounts of dirty water with large particles of dirt such as stones and organic material (e.g. from a garden pond) needs a thicker hose.

For different purposes, submersible pumps often have an adjustable universal adapter with which hoses with diameters between 3/4 and 1½ inches can be connected to the pressure port.

The best way to support the adapter with hose clamps is to ensure that the hose is securely attached to the pressure port without kinking. In this way, a good seal is guaranteed even in the long term. It is also important that you gently lower the pump into the water using a rope and not a hose, otherwise the tightness of the connection may be impaired.

Power connection

There are also submersible pumps with hydraulic drives, but most of the commercially available models for home and garden work with an electric motor. Most submersible pumps have a long power cable with a normal Schuko plug, which can even be connected to the nearest socket without an extension cable.
