    I am currently on the CC site at Grantown on Spey, at 08:00 this morning it was -9C it is now -10C

    Everything was fine till I went to the loo, internal temperature quite happily sitting just above 20c, it dipped a bit when I turned heating off to boil kettle

    But I have no flush water, mine is fed directly off the cold storage tank

    So been out to check, we have a standard Thetford type door to access the toilet mechanism, cant believe how warm it is in there, hot water pipes from Alde run through the compartment, so no idea where it is frozen, although I presume it is

    I am not too sure where the pump is, loks like it might be in this compartment, but this is a problem of being on your own, cant press button and be outside to listen.

    Not forecast to get much warmer, but have simple solution, that has in turn highlighted something

    Sink in loo is working fine on hot and cold, so used coffee mug to fill loo for flushing (we have a macerator not a slide valve, so it needs water) filled to level we normally would, takes 4 mugs, no wonder we have to empty the loo so often when away together

    Have to hope that when it thaws no harm is done

    David, was that Bev's coffee mug;)

    As for the loo, ours runs off the cold storage tank also but uses the same pump as the taps etc so if yours is the same it might be a pipe that has got a bit cold but would have thought that everything would be inside being a Hymer and all that(n)

    On my van the toilet does not have a pump just a switch that turns on the pump in the main water tank. All my water pipes are inside the van. Only the waste water tank is outside.

    Try depressing the toilet with a tap running. It could be a fuse in the line blown.

    Thanks John, good idea, our cold tank is also inside so that cant be the issue as all the pipes are inside

    Tried the button with another tap running, not that, but I do now know the toilet uses a different pump behind the toilet somewhere I can hear that running, bit of a mystery still, but seems more than a coincidence that it is so cold outside could be a complete red herring (been there a few times before)

    I think the toilet has a solenoid valve which operates when the flush button is pressed and lets the fresh water in the pump runs to top the line pressure up

    David, is the mascerator pump outside
    That would be as long as it a pressurised system which I would guess it is, but would rule out anything being frozen as David says its toasty warm inside the loo door area.

    Thanks hchris

    I don't do technical at all, but have had a look, it is not easy to see as the access is not ideal, but there does seem to be some kind of valve in the pipe work, but I also think I have a separate pump for the flush, I can hear something running when I press the button

    Am going to go out now, the sun will be on that side of the MH this afternoon for what it is worth, will hope it is all self healed by the time I get back (y)

    Macerator is inside, right under the loo, that is working fine

    Hi, we have a less-posh Hymer Exsis & no water through taps or to flush loo this morning=panic.

    Our cold water tank is inside & I had a look-could here the pump & we've had an air-lock in the pipes before. Unscrewed the blue cap on the tank & the one that the vertical pipes are fastened to.

    Miracle-tried taps in loo & kitchen & after a bit of spluttering-running water.

    I'm totally non-technical & rely on ritual & prayer (!!!) so apologies if this is a fat lot of use.

    Good luck,

    Relieved Roger

    Thanks Roger, the very fact that you have gone as far as undoing something puts you a league ahead of me technically

    I am delighted for you that yours is sorted, having no water at all would be a bigger crisis for me, but even then I am on a site with access to all I need

    I am still hoping for a genuine miracle and self healing :D(y)

    I believe that sometimes there is a one way valve that is in line and this may be located by hatch door which may be the problem. lets us know what happens when temp outside rises. good luck dont panic.(y)

    David, as you've found a way to use the loo, I wouldn't worry too much, as it may sort itself out when you drive south to warmer climes.

    Good luck.

    To show how non-technical I am I also opened the little black knob on top then when I went to fill the kettle noticed running water underneath the van! Panic-freeze & burst ???

    Then realised that the black knob is to drain the fresh water so nipped back & tightened it up again! Still have 25% left so OK.

    Hope you get your miracle :):D:LOL:

    Hi Roger
    The non return valve went on our Hymer Exsis i578 whilst in Germany in Oct. Fixed by ESSANJAY in Poole. The effect was that the boiler was self emptying back into fresh tank. This was a first for me so I thought an experience worth sharing

    Well as I guess was pretty much a given, it would appear the flush pipe work must have been frozen

    Disappointing, have had heating on permanently set at 21C, it has run pretty much constantly as well and as I put in OP, the external compartment where most of the pipes are seemed to be warmer than inside MH

    Anyway all resolved, when home and a bit warmer will look to lag the pipe, or at least get it lagged :)

    But you are right a lovely location

    Another great thing today, the site have sent their little tractor with snow plough right the way down from site to town centre completely clearing the pathway, nice touch
