In my Hiace Campervan (professional conversion), I have a simple set up, microswitch tap with sink and whale pump in a 20L container under the sink.
A few weeks ago on a trip my sink tap stopped working, turned it on went to work, then went dead. I assumed it was the microswitch on the tap, I replaced the tap (like for like), but still not working.
I taken the pump out of the water container and when holding it in onec hand, turning on the tap, I can feel a click in the pump, but nothing occurs.
If all the pump does is click, and the battery voltage is ok, yes it does sound like it's time for a new pump. However, make sure the battery voltage is ok first, and use a multimeter not any meters you may have in the van's electrics. They can be notoriously inaccurate.
