    I was told when I bought my bus to fill the water tank till it overflowed and done this ever since.

    Now en-route i alway loose water and generally arrive with about 3/4 of a tank on the gauge.

    Am I overfilling to start with? and if so why do i not just loose the overfill rather that the tank gauge telling me it's only 75% full then.

    If I fill it to overflow on the pitch it doesn't loose any water.

    Ideas???

    I noticed the same thing on our Georgie Boy. I once pulled up a couple of miles after filling the water tank and saw water running out. A quick check confirmed that it was siphoning out an overflow pipe. I can only guess that it's being on the move with the water slopping about is enough to fill the overflow and start the siphoning. It never did it if I filled up on site.

    Regards

    mine always reads 3/4 after filling to overflow.
    the guages are never accurate, at least on euro vans.

    It's exactly as Doug said - siphoning! I had the same problem when standing still, with the Georgetown. If I stopped filling it the moment that it started to overflow, I was OK but if I left it to overflow for a few minutes, it would set up a siphon effect and damned nearly empty the tank. Luckily the tank was in the bedroom and I coiuld actually see it happening.

    I think Linda put up a decent explanation on here not so long ago - and also gave a simple rememdy for it - but for the life of me, I can't find it. Mind you, I am suffering from a very bad case of man-flue just at the moment and can hardly see the keyboard to type on - oh, woe is me :Sad:

    If you can, attach a pipe to the overflow and raise the end above the tank!
