View Full Version : Think the water pump has gone

I have no running water (only one cold tap anyway) and no toilet flush. Have checked there is water and checked the pump fuse) so am assuming it must be the pump. Could it be anything else? If it is the pump, how the heck do I get to it as the water tank must be underneath? It's a '96 VW t4. Is it a big job and where do I get a new pump?
Any help appreciated :bow:

There are a number of ways the pump can be fitted so you need to find out what you have. Most accessory shops and yacht chandlers sell water pumps so it should be quite easy to find a replacement

They're all pretty standard, the in-line ones if it's simple system on a pump switch or tap microswitch.

If it is a pressure system one based on just opening the tap it will be more expensive. Just take the old one off and note the number and order one off the net eg CAK or Rainbow Conversions or take it down a caravan accessories shop and they will be able to sell you one similar.

Rainbow Conversions Dometic & Waeco Fridges & Coolboxes for Caravans, Campers and Motorhomes. (http://www.rainbowconversions.co.uk/) specialise in VWs and if you phone them they will probably be able to tell you straight off which system it is and which pump you need.

When you take the old pump off you can test it direct on a battery to make sure it is the pump which has gone and not the wiring or a fuse.

most inline pumps you can just disconnect the wiring from a terminal block and the pipes are connected to the pump via removable joints,so don't undo the hose clips,just the joints,which should fit the new pump. but in your t4 you might have a drop in pump,pity you can't pop round !

If is pump its not usually as bad a job as feared , fraid you just need to get your head in cupboards etc to find it or the access to it. Do make sure you test it and if can get to it move the impeller a bit. I had one that jammed . Once moved it went for years. Prob bit if rubbish.

Carol. Even I have replaced our water pump (Twice) so that should be a yard stick of how easy it is if I can do it! ;) Mind you ours is in the tank which is inside the van.

Ours is a pressure system and I think its important that you change like for like as it will depend on what Bar (Pressure) the system is designed for. I had to replace ours this summer in the Midi Pyrenees with a French pump. Seems ok so far.

oops ...its probably a simple prob carol and just needing a new inline pump...sadly since i fitted mine on the conversion and have since learnt they last on average 3yrs i think im going to have big probs de-constructing to replace it...good luck....im sure yours will be a simple replacement...;)

You need to establish if the pump is faulty first.

Does the pump come on when you open the tap, which if it does suggests you look for a micro switch at the tap and short it out to see if pump runs.
Are you aware of a pressure vessel in the water line in which case you should hear the pump running infrequently in very short bursts to maintain pressure. In this case there will be a pressure switch attached to the pump.
First job is to find the pump, take it out and connect to a battery to see if it runs.
Pump in my MH will be 8 years old and find a life expectancy of 3 years very low.

How to tell a pressurised system from a switched one (I've posted this before, but it bears repeating)

Switched; Turn tap off & pump stops immediately as microswitch turns it off

Pressurised; Turn tap off & pump runs on for a second or so as pressure is built up to operate the switch.


For either system, make sure there is 12v at the pump (on a switched system the tap will need to be on) If there isn't, work out why, if there is then the problem is almost certainly in the pump - check the brushes & internal connections. Any smell (or other signs) of burning, just replace the pump as the coils have had it.

If the pump runs & no water comes out it is a problem with the pipework or water supply.

Water systems are pretty simple really, THINK about the symptoms & the problem usually becomes obvious.

Hi carol,

I would think you should hear it pumping,the one on my van shakes the bed if you are in it and you turn it on.If you can get at it I would check the leads on it to see if they have come off or it may be an internal valve that could be replaced,but I am sure there is someone on the site that may have the same van.

Good luck Snowbirds.
