Question

how do yo fill a carver cascade mk 2 water heater with water i have just bought the van and not sure how to work it the pump is new but doesn't pump water into the tank

Answer

Assuming that you have water coming from your cold tap when the pump is operating, then there must be a blockage in the feed to the Carver heater. This is most likely caused by a faulty cold water inlet connection which screws into the tank at the bottom right hand corner. If you remove this part from the tank and ensure that the check valve inside is free to move. If not then you may need to replace the fitting, our ref. 128606.
