[GALLERY=media, 107023]Goo In Pipe by Nigel R posted 14 Sep 2021 at 4:16 PM[/GALLERY]Hi, I'm part way through having a boiler installed, and in a main valve and another compression joint my heating engineer has used a LOT of green goo that I think must be Boss Supergreen. There are gobs of it inside the ends of the pipe and in the valve. Like, you could make a cube of it 1cm on each side, kind of thing, in a 35mm pipe.

It's not water soluble of course, immediately anyway, and it seems to me you wouldn't want it in your heat exchanger. What do you think? A problem or a non-issue? I can fix the joints but wondering how bad a sign it might be.

My young heating engineer! He's taken a break while some late parts arrive and I picked up the valve he'd fitted then removed. It was full of the green goo, so I undid another joint, to the filter, which is the one in the photo.

Yes, thanks for your input, it's given me the confidence to do something about it. Looks like I might have tried a bit too hard to support a local lad starting out.
 
Boss white smears nicely round the pipe in front of the olive - and smells - he will go home smelling like a proper plumber . Not to be used on potable water pipes nowadays;)

To be fair to the lad if he is just starting out, so many so called tradesmen still put flux inside fittings , before soldering, he has probably been showed to do that by someone who hasnt a clue, good that you are giving the lad a chance
