Hi, my Honeywell 3 way mid position diverter valve needs changing.
It has an isolation valve (tap) on the input side and another one on the radiator side so I can shut those off, but the one that enters the cylinder does not have a valve to allow me to isolate it from the cylinder.
I am planning on shutting off the mains water supply, going into the loft and drain the water header tank and then undo the 3 x 28mm connections to remove the diverter valve. I know there will be some water still in the header pipers and coil in the cylinder but have I missed anything else I should do? I plan to isolate the wiring on the diverter and replace the wires likle for like. Should I drain off at least one low lever radiator also?
Any help would be greatly appreciated
