Maybe there's a pipe going in to next doors as well lol
I need to keep an eye on this following the service, it's still going in to lock out so something is wrong with it.
At this rate it will be cheaper to just buy another one, maybe going LPG since the boilers are cheaper than oil fired ones, think a new one of these would be £2700
You might have a leak in the line. Air in the oil would cause the boiler to lockout.
