I have a leaking speedfit fitting in a length of pipe work in the loft which is supplying my shower, I understand how to replace this fitting.
However, my hot water system is a megaflo system (in the airing cupd). If I turn off the cold water supply to my megaflo and turn on my shower to then disconnect and repair the pipe, will I lose all the pressure in the megaflo/ system? Or will the pressure reinstate when I turn the CW supply to my megaflo back on and eventually close the shower valve?
Grateful for any advice you can offer!
