I recently got gas central heating fitted by Scottish gas.The boiler is a Worcester Greenstar 28i Junior.Could anyone give me advice on the following:-
1.The engineer told me if I bled a radiator,the system/boiler woyld lose pressure and the CH would not work until I repressurised it.Could anyone tell me how to do this and what pressure do I put it to?
2.I am needing to change a couple of tap washers.I would be turning the water off at the rising mains before I did it.Would this cause pressure to be lost or does this not affect it?
Thanks for any help.
