Today I was putting the MoHo to bed for the winter. Whilst draining down the water from the boiler I noticed the 2 valves in the photo beside the Truma boiler, one connected to the cold and one to the hot water systems. Water came out of the bottom of the van ok when the solenoid was pushed down but what is confusing is the drain tube from the solenoid is the one connected at the left hand tee into the clear pipework which is before the valve. This suggests that the blue valve at the top is already open so why doesn't the rest of the fresh water system drain through this when the pump is running normally? The valve in the red pipe was closed so I opened it and got water draining outside. Van is a 2000yr B680 Starline.
