Hi,
I need to replace my central heating diaphragm, but before I undo any screws, I need some advice... I have already successfully replaced the hot water diaphragm, following these instructions....
Isolate boiler electrics, remove dhw flow switch, isolate cold inlet under boiler,open a hot tap to remove any residual water pressure
Do I need to do something different to replace the CH diaphragm? like release the pressure in the CH system to avoid mass water leakage or is that not necessary when replacing the CH diaphragm?
Thanks in advance.
