I have just moved house which has a Glowworm 30sxi sealed system installed.
I wish to de-pressurise the system so I can "T" off the bath pipes and install a shower over the bath. When the system is not bleeding water all over the place my plumbing is not too bad and I am competant to carry out the work, what worries me is the pressure in the system.
Is there a simple tap that I use, then drain the remaining pressure. Or is it a convoluted shut down and restart system?
