My van is a Hymer 570 circa, I used to park it on my drive and a keep a small heater on in winter, so apart from draining the on board tank I didn't have to bother much about freezing.
I am now storing on a farm, and I am not sure about draining completely. I can only find one valve, just to the rear of the water heater, but it doesn't seem to do anything. Its an "in-line" lever operated valve but up or down, I can't see any water draining underneath the van.
Can anybody help?

If it is the type with a yellow lever, this needs to be vertical and all taps left open, or it will not drain.If they are mixer taps leave them open in the mid position to allow water in hot and cold pipes to drain.

There should as has been said two valves together by the heater. The yellow lever should be lifted and the taps opened, the water will then flow out of a small pipe under the van. The second valve needs unscrewing slighly to allow the last of the water in the pipes drain out of the system, I have found it better to leave this closed until the hot water tank has finished draining. Occasionally I have found that lifting the lever does not start the water draining, if it does this I have pumped more water into the hot water system and this tends to start the syphon flowing.
