Hi all, first post here, I have recently acquired my first VW camper, a 1986 Auto-Sleeper high top T25, yes I know, only 31 years late to the party. Anyway all has been fine until last weekend when the water pump for the sink has stopped working. We were on a site without electric hookup and it was working OK off the leisure battery, although the tap began spluttering a bit and we put it down to the tank being nearly empty. Shortly afterwards, I turned the tap on and there was not even the sound of the pump kicking in. I've added some water to the tank so there is definitely some in there. The pump is mounted at the rear of the bottom cabinet adjacent to the rock and roll bed. I've checked for loose wires but can't see anything obvious, and the fuse in the panel above the window seems fine (have swapped with one of the other spares, no joy). It doesn't work on hookup either.
I am not sure if it is a micro switch type of tap, I can't hear any clicks when operating it, but when it was working, I did notice a small leak under the sink any time the tap was closed - the pump never properly shut off when the tap was turned off, and we always had to flip the switch by the fuse to stop it, otherwise water dripped out of the hose where it connects to the sink. It looks like a previous owner has had to use some silicone sealant in the connection between the hose and the sink inlet, which was past its best. Any ideas as to what the problem might be and what I should try next? I have got a multimeter but am not sure where I should place the probes to test connectivity, and it's a tricky space to get your head into too. All suggestions gratefully received
