Fitting a fresh water pump and tap

[Ross996]

Hello,
I,ve fitted my Snev sink and hob, Tanks are in. I've got a Comet single tap and a wee submersible pump, but not sure how to wire them up to the 12v system. I know that this is supposed to be simple. But !!! Can anyone put me back on track.
Thanks
Ross

If it is like mine you must connect +ve from a supply through a fuse or some such into your tap. Then back down to your pump where it will complete the circuit.

Positive to fuse, from fuse to switch (whether integral in tap or separate), then to pump. Other side of the pump to negative or bodywork. Pump is polarity sensitive so has to be connected the right way round. If using twin sheathed cable, just interrupt the positive (red) at the fuse and switch positions. Black is the negative return path.

Firstly, pmoc-2001 and 1664 thank you for your replies, your help is appreciated.
Am I right in saying that I have to run a double cable to the tap, one which will be an earth and the other a positive via a fuse, the positive then goes to the pump, which is earthed to the vehicle body. The tap has a double cable and I assume one is an earth.
Again, thanks for your advice. I am rebuilding my van and have managed all the lights and TV wiring,Built the units,fitted the rock and roll bed etc, but this tap is holding up production.

I haven't actually seen a tap switch version myself but if there's just two wires I'd imagine you'd go from the fuse to the tap and from the tap to the pump (red +ve). The black doesn't connect to it at all if it is a simple switch device. The black is the -ve / bodywork return (from the other side of the pump).
If you have a multimeter select continuity (ohms) and connect it to the wires; if you get a short when you operate the tap it's a simple On/Off switch.
