    Water tank sensor does not do overly much ( !! :RollEyes: )
    Anyone know if there is a replacement available ?
    The rest of the kit fitted is Truma as far as I can work out ( if that means anything at all ! )

    The thing is simply a tube with a ferit ring that goes up and down.
    The actual gauge on the Zig panel is working ( it just reads full all the time ! )
    Removing the sender from the tank and manually moving the ferit bauble thing makes not a jot of difference

    Hi check the earth lead on the sensor is making a good contact -this is sometimes an easy fix.
    regards, Dave

    best thing is not bother with it!

    the sensors are about as accurate as pointing at the moon on a cloudy night. :Wink:

    if your tank's accessible just have a visual from time to time:thumb:

    Right.. with the idea of a duff earth I decided to actually see wha was what..
    Turns out there is no earth on the level system at all.. It is merely a loop on the feed side that has the sensor in line.
    In the sensor is 6 reed switches activated by magnets in the ring ( which tturned out to be just a piece of black styrene or the like.
    Took it apart and found that 1 of the reeds was open and not switching no matter what, and 4 of the remaining switches were permenantly on !
    A quick search on line and I bought a bunch of the reed switches for a tenner ( got a couple of spares just in case )
    They should be here tomorrow and I will be putting it all back together..
    I shall report on the success or failure ! :BigGrin:

    Yesterday the reed switches arrived from RS Components ( Not the cheapest around but a quick reliable service )

    Replaced the duff switches and popped the circuit board back into its tube.
    I used some quick cure epoxy resin to reseal the bottom of the tube.

    Late afternoon and I went and dropped the assembly back into the tank.
    Perfect ! :BigGrin:

    Emtied the tak and then refilled it.. Readings were spot on all the way up.
    Well pleased .. A full repair for about a tenner ANDa bit more learnt about how 'things motorhome' function :Smile:

    Fresh water level gauge never a problem, however the black and grey tank, both always read full ... you are more than welcome to 'have a go':Wink:

    Well done on the repair... :thumb:
