Central Heating / Mains Water Pipe

[Colin73]

Hi all - hoping you can help.
Have had a drop in boiler pressure to zero over the last week every time the boiler is filled. Neighbour below has now informed me that they have small drips through their ceiling.
Boiler is empty and has been switched off.
I have also shut off the mains water as a precaution.
Do you think I can put the mains water back on until I can identify the leak? I'm not 100% sure if the central heating pipe and mains water pipe feed off each other in any way.
Thanks in advance, Colin.

Turn your mains back on.....the heating leak won't reoccur unless the boiler filling loop has been left open.
