Our recently purchased California is going in this week to have flat leisure batteries sorted,I thought I had better try the water pump,filled up turned tap on nothing,I tried to look at the fuse but they are difficult to reach under the front seat and there are 2 ,5 amp ones,how do I know which is the water pump and how do you get one out as there is nothing to get hold of.The manual says you should take it out in the winter once the system is drained,if this has been done how do I know where it goes back as there are lots of spaces
Not knowing which vehicle you have, as you're still Looking to Buy according to your profile, the fuse only needs to be removed so that the Tap can be opened to allow water to drain back from the pipes. In fact it is easier just to locate the plug/socket connection for the tap, remove cutlery draw and follow the wires from the base of the tap, and just unplug it.
1. Do you hear a click when you open the tap? this is the microswitch.
2. Do you have the Shower Connection? If so Open the kitchen tap and turn on the Shower. Water should flow if pump is OK.
3. The fact that the Dealers Flattened the Leisure Batteries leads me to think they are unlikely to have removed the fuse for the water pump.
4. If the Tap clicks and Pump doesn't work it could just be stuck. If under Warranty then Dealer. A possible quick fix is to try and blow down the tap, with the tap open. Opening the top of the water tank to take out the pump is not easy without the correct tool.
