22mm copper pushfit

pboae

I need to shift a couple of 22mm (water!) pipes around. They are against plastic, so I can't easily solder them, and it's a really tight corner, so plastic pushfits aren't going to fit. I was wondering about trying to use the copper push fit fittings. I've only tried them a couple of times on 15mm (out of curiosity really) and they needed a serious shove to get them engaged. I was wondering how the 22mm are to join, do they require super human strength to engage them, especially in situ?

erm 22 mm push fit fittings as hep or polly plumb are alot harder to push on then 15mm ones so i guess the copper 22 push fit will be harder than the 15mm ones but i think john guest ones the white ones from bnq are alot easier cause after there on you screw the nut on to tighten them up just wondering if your gonna have the room to cut the pipe even with a pipe slice if you cant get a push fit fitting on
if you can solder you could always get a heat mat to put over the plastic pipe
hope this helps
sorry still dont think i have answered ur question

Thanks for trying anyway :-)

I wouldn't get a slice in, it would have to be a very careful hacksaw job. I think it might have to be compression fittings, but it's such an awkward space, the push fit would have been easier (or maybe not!)

sounds like it!! hard to imagine without a pic but there is always a way round everything goodlook

Pssst

Maybe use could use electric heating tongues rather than an open flame to due your capilliary soldering?

ghd's might be good

Oh, that made me LOL for real, I can just imagine my niece's face if she caught me soldering with her beloved GHDs. (I don't know anyone else who owns a set!)

i thought these were the hotttest things around without burning ur scalp if you can do it without burning ur scalp it wont melt the plastic 100 bar is a bit steep to buy some though hey i could set up a ghd hire company

can't you just bend a piece of copper pipe 90 degrees to fit the corner and then use push fits to link???

There isn't space, the pipe comes up from under the floorboards, immediately into an elbow, straight for about 3", then into another elbow, straight up for a couple of inches, then elbow and across.

The second to last elbow weeps and needs replacing anyway but I want it to reroute it anyway, but there's not enough pipe between the last two elbows to join anything to it, so I'll have to cut it on the first straight run.

I recently bought a Draper soldering heat pad from ebay. For the pricely sum of £3.99 it does a great job when used with my propane blow torch. It's quite a thickish padded mat, so the heat is unable to pentrate (as is the case with those other thin one). If you have soldering equipment already, then maybe give that a try? It's certainly done me proud.
