What is a Water Pump?
The small electric pump that gives you running water from the taps.
Simplified animation — not to scale.
In plain English
Open a tap and this little 12V pump switches on automatically, pushing water from the fresh tank through the pipework to wherever you need it.
How it works
A pressure switch (or a simple micro-switch style pump) senses the drop in pressure when a tap opens and starts the motor. It stops again once the tap is closed and pressure builds back up.
Signs of trouble
- ⚠Pump runs constantly, even with taps shut — usually a leak somewhere in the system
- ⚠No water despite a full tank — check the fuse and the inlet strainer for debris
- ⚠Loud chattering noise — often trapped air, or a failing pump
