I can't for the life of me find the hot water cutoff tap in my hot water system.
The CH/HW system is a Potterton Profile boiler, leading to a hot water cylinder with two outlets (I think!) that exit the boiler and disappear under the floor - one looks like it's heading for the Central Heating, the other looks like it's heading for the hot water taps.
I'm trying to stop the hot water supply briefly to undo the taps and replace the kitchen sink, but although the cold water cutoff is directly under the sink I can't find the equivalent HW one.
Can anybody shed some light on the usual hiding places for these things? Am I barking up the wrong tree wrt the cylinder outlets?
Many thanks,
Shano
