I have a autosleeper Kempston xl which is a few months old. When running the kitchen or bathroom tap on cold we seem to get so much cold and then it runs hot for a short time before going cold again. Any ideas before I have to go back to Marquis? It even
runs hot out the cold tap in the bathroom which is not a mixer tap.

    I wonder if the cold pipe (from the fresh water tank) passes the hot water boiler or do the hot and cold pipes lie side by side?

    in either scenario, its possible that heat could transfer from the hot system into the cold pipe 'warming' it slightly....hence the impression that the cold pipe is dospensing warm water, prior to it returning to cold as the flow increases....Happy

    Although I have a caravan, I get heat transfer if the Truma heating/hot water is on. The cold runs cold and changes to warm for a short while.
