I had a plumber round recently to do a radiator, whilst there he glanced at my boiler - pressure was at zero. He mumbled something about a tap, found some weird little thing that looked like a wine bottle opener, slotted it on to some kind of 'tap' at bottom of my boiler and turned it.
That sorted it - reset the pressure. Sounds same, maybe it's that?
No, I tried that. The issue was it didn’t work when I did. Turned out the pressure relief valve had broken. £100 to replace so bit too bad. Thought it’d be worse.
