I have an issue with HW being drawn when all taps are turned off. This is manifested by the Stuart Turner Monsoon pump which runs on when HW is turned off at the tap. When I close off the main HW supply (green arrow), the Monsoon pump stops as required. At the same time there is still a trickle of HW at the tap. The stop cock at main HW supply is new and works as required. There is no apparent HW leakage as HW tank stops filling when full, yet there is still a draw at the Monsoon pump.
This is confusing to me. Perhaps it'll be clearer if somebody explains the purpose of the line at the red arrow. The pump below the red arrow is disconnected but the stop cock is broken so it can't be shut off.
