    Time to ask your advice again
    This trip the water pressure got less and less and finally has stopped altogether. There is still 75% water in. We hoped it was a water bubble but it seems not.... As far as we know we have not burned out the pump.
    The van has been serviced and kept in good condition since 2006 (Hymer) we bought it in February.
    Any thoughts appreciated. We are using water containers.
    The annoying thing is we have just had everything repaired and set off again.

    Do you think it's just a coincidence that this has happened the first time it's used after Simpsons repaired it? (Changing locker keys outside and converting LPG filler port to outside on skirt)

    just coincidence I think.. .. the two jobs done are not related to the water pump..

    is your tank under the floor.. do you access the pump via a small hatch ?

    If the mesh is clear? If so, before buying a pump can you check the 12v is at the pump.. do you have a multimeter ?

    Also worth checking the pump connections.. they could be corroded causing a low voltage at the pump.. making it run slow..


    Changing over the pump is not a difficult job.... just basic diy skills.. small screwdriver and adjustable pliers ..


    Switch off the 12v at the control panel.. Disconnect the pump wires , note wire colours .. it looks odd that it is connected blue to brown and brown to blue...
    (in the Hymer Blue is Positive.. on the pump Brown is Positive )

    unscrew the cap on top of the tank holding the pump, lift out, unscrew the nut holding the pipe to the pump.. change over pump and re connect


    If you prefer to go to a dealer, they shouldn't charge more than 1 hrs labour + cost of pump ..

    It'll be a load of Norfolk limescale broken up by that soft Derbyshire water gumming the works!
    -Probably!:D

    I'm with the others here, best to check for blockages first.

    note wire colours..

    NB.. forgot to say..

    .. be aware, when you take the pipe off the pump you will get water running back from the hot tank.. sponge comes in handy .. :)

    Update..

    decided to replace my pump with the new spare I bought last year from Marcle.. the cable was hard with age and being submersed in water all these years

    I also replaced the short braided clear pipe tail as it had become hard and brittle with age.. there was enough slack in the pump discharge pipe to nick a couple of inches..

    you will also have to fit new spade connectors to the new pump AFER the wire has been pushed through the cable gland.. or change to a chocolate block connector..

    I will keep the old pump as a spare

    Thanks checks done and it is the pump. We are ordering from Marcle (thanks Jim) but there seems to be no express shipping option. Only way to speak to them is to email first!!
    We are only home for one day next week so need it to get there by Monday. Do you think it'll get there if we do a regular order or should we wait for a reply from their email? Aargh!!!
    Hoping to head to denmark monday!!
