Plastic push fit on copper

[dormermike]

Hi all

Wondering what folks think of this. Had a new boiler fitted a few months ago, right from the get go I said it had to be all copper. No problem, we only use copper they said. They came and installed and did a good job, and mostly happy with it. Few niggles like having to clean off massive amounts of flux off the joins, and a couple of pipes are touching each other which is a bug bear of mine. In moving one of the pipes, I looked under a floor board (actually chipboard t&g) and I see two plastic speed fits joining two copper pipes, hot and cold. Now I can sympathise as to why this was done, as access was terrible, but now I'm worried that if I move the pipes slightly (approx 2m lengths, unclipped so they have a bit of give) will it disturb the plastic elbows and cause them to leak?

Or are pishfit on copper fairly compliant like that? I have confidence in soldered joins but no experience of plastic push fit.

Thanks

Pushfit receiving copper is absolutely fine as long as the joint is made correctly.

So it's robust enough to take a bit of knocking etc?

(Provided it was done properly in first place of course..

Absolutely. Just don't go too mad with it, otherwise it may become detached. Ime, they're usually quite robust.

Hi
Used plastic and copper together when done a complete overall of all my plumbing system, that was 20 years ago. Had no problems at all
