Water Pumps

To get water flowing from the fresh water tanks to the taps, you’ll need a pump.

Manual pumps provide a budget friendly and easy installation option for a cold water set up.

Accumulator

12v water pumps switch on when they sense a drop in pressure, like when the taps are turned on.

An accumulator reduces how soon the pump switches on by acting as a pressure store.
