Water pump issues

[Waynethefixer]

Hi everyone,

I have a lunar clubman se 2010. When I am connected to the water and I turn on the pump, the water just gushes back out of the inlet. Has anyone any ideas what the issue might be?

I assume you have a submersible pump in the aquaroll?
Turn on the pump? You mean the 12 v supply isolator switch?
Then if you turn on a tap what then? I assume you know how to bleed the air out of the system ?

Where you plug the water intake socket into the caravan there a few O Rings which perish overtime. This can be one of the reasons for the problem you have.

Others will give more thoughts .
