Please excuse the ignorance.
I don't know how to isolate the hot water (for a tap change) from a primatic cylinder - I know how to drain one down but not how to turn off the hot water.
I'm assuming I will be facing a primatic cylinder. Cylinder with a tank above it (all combined into one unit) with an F&E cistern above it. Two pipes at the front for heating.
There's no visible isolation valve before the cylinder but there is one after the Tee to the F&E.
So, how do I turn off the hot water? As always, any hints gratefully received!! (Although perhaps not a "Get a plumber in"!!)
