I have an issue with a Saunier Duvall F24E condensing combi losing pressure. It has gone from needing to be topped up every few weeks, to now every day. I have tightened the valves on the radiators and can't see any visible leaks outside of the boiler or on radiator joints etc.
I have had an engineer around but when he arrived he told me he didn't work on that make even thoughI had told him the make and model in advance!. He made no effort to check for a leak (I didn't tell him I'd tightened the valves already) but stood there with his arms folded and tried to sell me a new boiler. He walked away with his call-out fee having made no checks whatsoever - not even a pretence of care.
Reading on here I see I could possibly attempt to re-pressurise the expansion vessel myself using a bicycle pump.
My questions are:-
a) Is this the correct valve/ (see photo)
b) Can I do harm? e.g. if I over-pump it?
c) Are all valves the same size? As per bicycle pump?
d) What precautions should I take? Aside from turning the electrics off?
e) How likely is this to fix anything?
Failing this can anyone recommend a proper heating engineer in the Twickenham/Richmond area that can deal with a Saunier Duvall boiler? (The cowboy I had said no-one will work on them!).
