another one whilst fixing the first one.

I find that often there are many faults, and it is only when something
actually stops that people notice there is something wrong.

I then go theough and find and rectify each issue one after the other..,

Indeed so. But to fully fix this boiler I would have had to come back
another day with the return/pump inlet manifold and PRV assembly
(assuming that such a part was available). At the end of it they would
have had old Puma.


This was a classic example of what I said in the Boiler Choice FAQ.
A better boiler not only has cheaper and more reliable spares but it is
also more repairable.
