I have noticed that when I draw cold water from the kitchen tap, it runs cold, then it goes to luke warm, then back to cold and then luke warm,  so I can never get just cold water for the dog bowl it has to be lukewarm.  Is this normal, or is there something wrong please.

Follow the route of the pipes around the van sounds as though the two are touching together side by side somewhere

2nd that unless the non return valve in the water heater is letting hot water back down the pipe and into the barrel.

My thoughts too. Do you notice it especially just after you have used the hot water tap? If there is hot water in the pipes, then it could be that the pipes are touching. Try using the cold water tap as soon as you come back to the van from a long day out, without using the hot water first. If it doesn't happen then, I reckon it is the close proximity of the pipes. If it still happens, then Michael might indeed have hit on the answer?

Ours does this on the washroom tap, and I believe it is to do with hot and cold pipes running close to each other (touching) at some point between water heater and taps.  It would be  a hassle to trace the pipes along their route (behind major fittings), and too minor to warrant the trouble.

Thanks for the replies.  It has nothing to do with the aquaroll getting warm, otherwise I would not get any cold water, and it happens all the time, at night, early morning...
