I have an old combi boiler with a weak pump and could easily fit a new pump externally, in addition, not as a replacement.
Can anyone please tell me if this is OK?
(I have already fitted an external expansion vessel successfully when the existing, inaccessible one failed).
Helpful advice will be much appreciated.
