Hi, I am going to fit a new hot water cylinder in our airing cupboard as the old one's coil has split and causing the small tank to overflow
I have heard the cylinder connections can leak, so would like to ask how's the best way to stop them leaking/dribbling?! I was going to use PTFE tape around the threads and compounds too. Is this correct?
Secondly just to confirm to replace the cylinder, I drain the cylinder by closing the gate valve to the cylinder cold feed, open hot taps in bathroom, and drain ia the draincock near the cylinder.
To drain the primary circuit I will need to drain the whole heating system down too from the draincock near the downstairs radiator
When piping the new cylinder, as it's in a tight space, is it best to add a small pieve of pipe near the old ones before putting the new cylinder in place?
Have I missed anything out? Or is there anything I can do to make it easier?
Also when re-filling the system I'll add X100 to the small tank.
Thanks for reading my post, I will appreciate any advice or help given.
