    Compression onto brass solder meter union

    Hello I am having a massive argument with some guys over whether this is the correct procedure for these fittings. I have always been told (by gas college and gas coaches) that you do not use compression fittings on brass pipe as the olive doesn’t compress into the pipe. It’s not riddor but it...

    Removing a radiator with a compression fitting between valve and radiator tail rather than a union fitting

    Hi, I am replacing some radiators and using new fittings. Most radiator valves now come with a compression interface rather than a union interface to the radiator tail. It seems to me that it would be rather difficult, if not impossible, to remove a radiator at a later date for decorating when...

    Radiator fittings types????

    Hi Guys, I'm just coming to the end of a refurb at home, and fitting a new rad in the dining room, but just noticed that the trv and lockshield are 15mm compression type fittings, which means I'll have to drain the whole system down if I need to take the rad off in future, instead of just...

    28mm gas meter union?

    Can anyone recommend a plumbers merchant that has them? I have been to pipe centre and parts centre and they don't. Or is it ok to come off the meter with a 22mm union and branch up to 28mm off the 22mm? Right next to the meter?
