Pm a mod with your gas safe card ( o right we don't have any anymore)
For obvious reasons, we won't and can't help you fiddle with things that fall under strict laws, laws that are there to prevent people from blowing themselves, or other people up.
<tongue-in- cheek>We're not too fussed about them blowing themselves up - Darwin Award and all that. But it's the other people we're bothered about that didn't have a choice in the matter.</tongue-in-cheek>
UKPlumbersForums.co.uk is here for all types of plumbers. But to repair or install anything that requires you to comply with laws, you'll need to follow the correct procedure to prove you're competent (i.e. registered with Gas Safe and have a Gas Safe ID).
You're welcome to ask about water plumbing and whatnot. But lay off the Heating Engineer-related questions please. Carrying on may result in your account being restricted or suspended from the forum.
