Hi
I wonder if anyone can help me .
Our old combi boiler was replaced in December because the water
jacket
was leaking & could not be repaired [ Grant Boiler], soon after
fitting the pressure dropped again, Engineers came & found a small
leak.

One again the pressure is dropping, i am now told itmust be a leak in
the house, probably under the floor boards & nothing to do with
them .
The problem did not exist before the new boiler was fitted

On top of that i have now also had an account for commissioning the
boiler, this was not done at the time of fitting.

Could i question why a separate expensive trip was required for this,
Thanks
Wally

do reply !
