How to stop a copper pipe turning in the wall?

[shagster]

I put in an external CH drain stop-cock, one of the copper ones on the end of a copper pipe, which then goes into speedfit elbow. I can't figure out a way to stop it turning in the wall when I open it with a spanner - any ideas?

thanks,
S.

Can't you just put some grips (Footprints or waterpump pliers) on it to stop it turning?

Yes, I can remember to do that, however there is no guarantee that whoever is servicing the system after me will bother do the same.

I am pretty new to speedfit, so I've never had this problem before as the stopcock was always going to soldered joint inside the house. I get the feeling that rotating pipes while the system is under pressure is asking for future problems.

Always had copper inside the house in the past, so there was always a bit of solder stopping the stop-cock from turning. I know the way to solve this which is to go buy a piece of copper put an end-feed elbow on the pipe inside the house, put another length of copper on that and them secure the pipe to a joist. Just wondered if any Speedfit experts out there knew of a better (quicker, less fiddly) way.

cheers,
S.

Don't let someone that daft in to do the work.

That advice is useful as a chocolate tea-pot. No way of knowing who's 'daft' and who's not.

I think the point is that if it won't undo without turning then whoever does it will have to grip the fitting to stop it. It's not a case of 'remembering' to do it, surely, if it turns then you just figure how to stop it?

I think you're missing the point. I don't want it turning in the first place. I can turn it with my hand. My kids playing in the back yard can turn it, even with the mastic that I squirted in around the pipe. The speedfit fittings don't have any resistance to rotational forces whatsoever. I tried to wedge in some bits of wood around the pipe but they didn't help much either.

If no other ideas I'll just resign myself to putting in a soldered elbow the other side, put a pipe clip on the extra copper tube, then go speedfit from there on. I just *hate* soldering stuff under the floor .

S.

Why not use a backplate and screw it to the wall.

Who said plumber was easy.

Ah. so you're saying I should have bought one of these:

Instead of one of these:

Looks like it'll work, thanks.

Sure as hell wasn't me!

Are you for real Shagster????

do you not think these are problems proffessionals face every Day??

TBH serves you right for using plastic push fit!!

any decent engineer would always use a pair of grips to "hold against" it's just good engineering practice even on copper or steel pipes

Yes.

Yes, that's why I'm asking on a forum where I might get an answer from one such professional. Why else would I post here?

Are you for real? Thousands of professionals use plastic without issue. You're obviously a troll.

If you tried one of those utility keys and it turned then you'd not bother holding against. It's a RUBBER seal. You're not living in the real world if you expect everyone to do that. You only hold against if you know you have to put force on it.

Put a secured kink in the pipe

45 deg elbow and a 45 deg street elbow, with a pipe clip either side.

You are if you think there could be a way to stop a pipe rotating in a pushfit joint without holding it or altering it.

He was trolling, so today he's a troll.
