    Had a problem whilst in Germany recently which may be of interest to others. We were having lunch in the van when there was a sudden and loud gush followed by water dripping from the sink area.

    Luckily, we were sat there and were able to switch the water pump off quickly. I could see through a gap in the kitchen sink cabinet that the hot water feed had come away from the base of the tap so had to partially remove the sink unit to get at the hose clip to refit it.

    I dread to think what we could have faced if we were not in the van at the time as we had three quarters of a tank of fresh water on board so now we try to turn the pump off whenever we are not using it.

    The van is an Autocruise Alto panel van conversion and I guess that the water system is pressurised when the pump is on which must put some load onto any joints in the pipework?

    That's right. Just like at home, with normal taps.

    Ours, like many others, has a switch in the tap and that switches the pump on "on demand". Now you posted this, this looks a safer system but a bit more to go wrong in the tap.

    I haven't had a problem like yours yet, but being aware of the possibility of it happening and returning to find the tank emptied into the m/h I do, when I remember, turn the pump off when going away from the van.

    Mine is also a pressurised system with an anti surge chamber. I also switch the pump off when we are away from the van or if its not being used. My old Tiffin had the same system and I finished up with a locker full of water when a joint blew whilst at a meet in Oswestry a couple of years ago.

    I switch the pump off when not in the van and also when sleeping (aka stupor). :thumb:

    You being a serious dabbler in sparks should have an automatic switch so that when you lock the van from outside it trips the pump. Fail-safe.

    I'd link ours to the alarm but for the fact that it's not needed.

    Also have a pressurised system and always turn the pump off when away from the van for the reasons others have mentioned above

    Pump

    Same again, always turn it off. Had a similar experience years ago with a loose pipe although only a small amount of water escaped.

    If really worried about it, turn pump off then open a tap to relieve pressure from pipework.

    Common problem. Yes always turn pump off when not in use
    My Rv has a switch in the kitchen. And another in the shower room
    So you can turn pump on / off as required

    The yanks think of every thing :thumb:

    :Eeek: I've never even given switching off my pump a thought!

    Mine are microswitch taps, so the pump won't come on if a pipe goes - as to wether or not it will dump all the water from the tanks into the mh - don't have a clue! :Sad:

    If you have micro switches I dont think you have anything to worry about. Its only the pressurised systems that would pump all the water out in the event of a burst.

    Always turn ours off when away from the van, but not usually at night in case someone needs to go!

    I always turn ours off when we go out and at night. There are various switches both inside and out, one being by the toilet, to turn it back on if required. If full, 85gals would make a teeny tiny bit of a mess. :Rofl1:

    Yup! me too, When we were overwintering in Spain the boiler kept dumping the water during the night and then the sodding pump would kick in and would have run until the cold water tank had emptied. Now we always switch it off before we go to bed or leave the van.

    No longer a problem when the boiler takes a dump!

    Got the habit from my dad when I was little and we had caravans. Always turn it off at night, when driving and when out.

    Someone mentioned anti-surge, what's that?

    Like Melchior we are caravanners at heart and turn everything off everytime - saving battery.:BigGrin: Even now in our RV and on electric we still turn lights off straight away and turn the water pump off after use.

    Friends of ours accidently left a tap in the bathroom running with the plug in the sink and because the water pump was always left switched on it flooded the RV.

    We even turn the gas off when travelling too.

    Regards Brian and Chris
