The over pressure 'saftey valve' is leaking slightly .. ie the system
pressure is slowly dropping and the there is a slow 'drip' from the
vent pipe out side ..
I see the valve appears to be part of the boiler - can be un-screwed -
leaving the housing behind ..
Question is ... can it be serviced ? or is it a sealed unit ? if you
unscrew the 'insert' do you also need to remove the housing to
change it ?
Just need a idea before I make a start !
You would replace this with one from a boiler spares shop (real or online).
The VCW is almost unique in having a 22mm discharge pipe
22mm?
Are you sure?
Mine was 15mm
