Disconnecting a megaflow

Options
Last night a pipe in my house sprung a leak.  Almost certainly a cold water feed although I cannot tell for sure because the leak is from one of several pipes which run out of a wall behind my (large) megaflow cylinder.  I need to find a plumber to fix this (my previous plumber has retired) and as it looks like the job requires disconnecting and moving the megaflow and then reconnecting it after the leak is fixed I am wondering how big a job that is and whether it is likely to be in the expertise of most plumbers?

    It will need a G3-qualified plumber as 'unvented/pressurised', but should otherwise be normal plumbing and not a big deal.
    Have you stopped the leak? Shut off the mains?

    If you are having to remove the megaflow then it's a big job as you need to drain it and disconnect it and then reinstall it. It's not going to be cheap as it's time consuming.
    Its not in the expertise of most plumbers because only G3 gas engineers will and should touch it. I would get a G3 plumber out to look at the leak and see what they suggest.

    Yes, mains shut off and tap opened to release pressure.  Now to search for a G3 plumber - I live in middle of nowhere!

    I live in the middle of nowhere and my oil heating engineer is G3 certified (and fixed the tank here after I moved in which had never been serviced and was no longer pressurised - he now checks it annually). So it might not be as much of a problem as you think.
  • No one needs to be Gas Safe registered to be G3 qualified and accredited.  They are separate qualifications and there are many G3 registered plumbers who are registered with organisations other than Gas Safe for that purpose.
