Water Pump

Recommended Posts

Before we purchased our caravan (last Friday), the service report stated the Truma water pump was leaking. We have tried to use it anyway, but the pump switch does not come on. Taps were open and the switch on the water storage to correct way.

Could it be that unless the pump is working correctly the pump switch would not light up?

 

Also have looked to see where the fuses would be for the control panel, but they seem rather elusive, found the general ones in the front right under the seating

 

Thank you

With an older van, recently purchased, nothing can be taken for granted, previous owners could have changed things.

A cheap multimeter (around £10) is an invaluable tool for fault finding.

I will assume that the van is fitted with a known good leisure battery and is plugged into the mains.

There should be two fuse boxes (or panels) and a set of mains trips.

The first fuse box (which you seem to have found) is usually in a front bench, close to where the 12 core cable comes in and is for the road lights.

The second, for all the internal 12v items, is usually either close to the battery box or control panel. In addition there is usually an inline fuse in the main feed from the battery.

Do you have a submersible pump? (on the end of the pickup hose)?

Or an inboard pump connected into the internal pipework?

Do the 12v interior lights work?

Thank you for your reply.

The battery is brand new and fit for purpose to take into account using the wheel movers.

Every thing else works as it should lights, fridge, heater etc

The pump is submersible, goes in the 40 litre container, the pump is - Truma Crystal Maxi Pump

as the pump is a plug in one, just connect 12v across its terminals from a battery to see if it works.

That should prove or eliminate something

As macafee2 has said. also  the contacts are like a caravan light socket (7N) with a pin cut into quarters , you could try easing a screw drive in to spread them a little,

If you want to spread the the terminals use caution. They will not take much bending and its easy to snap off one of the segments. Point 5 of a millimetre should suffice. It is also advisable to put a dab of copper grease on the outside surface of the terminals. This helps to improve electrical contact.
