Er, are you talking about turning off the heating aspect of the boiler or
turning off the water supply? I thought you were talking about replacing a
tap washer, which mean tuning off the water supply to that tap (either by
closing a stop vale of by turning off the rising main). Turning off the hot
water control at the boiler would simply ensure the water to the tap was
cold rather than hot - it wouldn't turn off the water flow itself. Maybe
I've misunderstood your phrase "her boiler has separate controls for turning
the CH & hot water on & off" - maybe you are referring to a tap rather than
a control switch. Or maybe your system has motorised stop valves, which
*would* mean that when HW is turned off at the boiler controller, water flow
was turned off.
