Time for a new boiler?

the pump can be making more pressure faster, than you are leaking it.

Sounds like the expansion vessel needs repressurising

Thanks for the suggestion.:)

Ok, maybe a dumb question, but does that mean that the pump is faulty too?:o

Also, before the engineer came out, we were having issues with hot water in the kitchen. When the CH isn't on, it seems to take ages to get hot water coming through the tap, if at all. Sometimes turning the tap off & then back on again gets a burst of hot through then back to likewarm/cold.

The problem seems much worse since the engineer came.:(

He has already told you that you have a faulty diaphragm which is undoubtedly causing your hot water problems. Unless he took the old one out, stretched it a bit more and then refitted it, it's unlikely that he has exacerbated your problems.
