Fantastic video. Almost every issue I've had with the caravan over the last couple of years has been with the water system. Thanks for explaining things so well.
Hi there, we arrived onsite with our new van waterpump not working. Tried everything, phoned dealer but couldn't help till next morning. Watched your video and got it working. Cleaned up the exterior contacts and eureka, it worked. Thanks very much. We were 100,s miles from home, life saver.
Hi Dave another good video. We have an ongoing issue with our new bailey purchased in Jan this year where our whale pump suffers with phantom pumping and our dealer has had it back 4 times and currently in with them now. We have had 3 new water pumps , parts have been changed inc non return valve, added an inline surge damper which made it worse. They are at a loss as what is causing this. They are adamant its not a leak and not the pressure switch. Any ideas what could be causing this to happen? Gaz
Sorry to hear that you are having issues with a new van. One random possibility. When you fill the system and/or set the pressure valve. Do you do this from the furthest tap from the inlet valve? (Usually the shower) Also when filling vent it from/at the shower. The last thing would be the rubber O seal on the external pump connection (if there NO onboard tank). I seem to recall our friends had a similar issue. If there's air left in the system then you will get phantom pump activation. It also has to be said that some phantom pump running is somewhat normal.
@@DTSquared when priming I start in the shower and end at the kitchen and the o ring has also been replaced. Thing is we have had 3 Bailey Caravans previously and not had any issues with this before. I'm hoping my dealer will fix it on the 5th attempt. They did suggest I turn off the pump when not using the water but that's not the way to use it according to whale after a conversation I had with them last week. What they did say was to make sure there is no leak before altering the pressure switch. Thx Gaz
Thank you for the video, I have an 2017 elddis avante with the pressure system. When you turn the power switch on it pumps water in fine, once at pressure you turn the taps and nothing. I have to manually turn the power on & off again for the pump to start, would you have any ideas please ? Mike
I would say it is most likely that the pressure switch isn't calibrated correctly. Locate the pressure switch adjustment dial and then with the pump turned on try turning the adjustment dial in or out until the pump starts running. Then back it off just a touch until the pump stops. It could be that the pressure switch has failed but calibration is the first thing to try.
Hi Dave, We recently took delivery of a 2016 lunar Venus 540 and on our first trip we found the water pump not working due to a blown fuse, we replaced the fuse which we thought had fixed the problem but shortly after the fuse blew again. Is there any obvious causes of this? Thank you
If the fuse is blowing then it's likely there's either a wiring fault such as a short or bad connection. Or the pump is pulling too much current, so could be faulty.
Cheers Dave, luckily the people we bought the van from were kind enough to come out and investigate, it was indeed an issue with the whale pump which they replaced for us. Thanks again
Hi, thanks for video. I have question becasue at the switch there is and ext and int, do we have two pumps there ? because when I switch to ext nothing happens, shall you explain this topic to us ?
Hi, if you have "INT" and "EXT" labels on the control panel then you will almost certainly have an onboard water tank in ADDITION to the temporary external tank (usually an aqua roll or similar). If you switch to INT then you should hear the pump running in the onboard tank (it's easy to hear as it is inside the van). Unless you've filled the tank up it will likely be running dry. The EXT setting turns on the external pump but you will have to have plugged it into the side of the van (as you should see in my video). If the external pump is plugged in but not running then check the contacts as I showed in my video. Good luck.
I have a whale pump that will not turn off after running water, if i turn the switch off then on it is fine until I call for water again, I dont appear to have any adjustments for pressure either on the switch (yellow back 3 wires) or externally on the pipework... Any suggestions ?
Does it start running as soon as you turn the system on? Does it eventually turn off after a while? Can you see any electrical wires going to the tap itself?
@@DTSquared Hi Mate, after a bit of googling I beleive I have resolved it, ... it appears I have an IC pump and it just needed calibrating... to help others 1st press and hold the small button on the back of the switch till the light starts flashing 2nd turn on shower (Cold) for 30 seconds 3rd Press small button again after pump has ran for about 10 seconds .... it sorted mine so hope it helps others
I have this pump, and the green light now stays on even when taps are closed! When the pump is plugged in it blows a fuse immediately. Any ideas on this. Thanks.
Are you certain that the motor is running or at least trying to and that the impellar is stuck? If so, I can't see any way to get to the impeller without breaking open the whole unit, which would likely destroy it. The lower blue filter cap comes off easily enough but doesn't expose much of the impeller. You could try disconnecting the water hose at the top of the pump and blowing through it, which could possibly clear any debris. As a last resort I guess you could try temporarily connecting the power with opposite polarity. Depending on the motor type, it may reverse the direction which could free it. But that's a long shot and I couldn't guarantee it wouldn't also harm the motor. Tbh if the impeller is jammed, then the motor is likely to already be burned out if it's been powered on for any length of time. Best of luck.
Hi, every hour or so my onboard system makes a noise like the water is being turned on but , it only lasts about 2 seconds then goes off. The water is running fine . Any ideas what the problem could be setting off the onboard pump?
Fantastic video. Almost every issue I've had with the caravan over the last couple of years has been with the water system. Thanks for explaining things so well.
Thank you, I'm so glad that you found it helpful.
Thanks Dave, had this problem early last year, I checked everything and by adjusting the pressure valve it started working fine,👍.
Thanks Buster, I was in two minds about leaving the section about the pressure switch in , as I thought it may be too uncommon. Glad I left it in 👍

Very helpful thanks. My problem was a new battery was required.
I'm glad it helped. Low battery power / voltage can certainly cause issues with the pump.
Great video
Thank you

Would you any suggestions on how to free the impeller on a pump.
Are you certain that the motor is running or at least trying to and that the impellar is stuck?
If so, I can't see any way to get to the impeller without breaking open the whole unit, which would likely destroy it. The lower blue filter cap comes off easily enough but doesn't expose much of the impeller.
