Connecting 10mm copper to 10mm speedfit?

Hi all

Sure I read in here that people prefer to use a compression joint with appropriate inserts rather than a standard JG plastic coupler.

Am I correct here?

Thanks.

For me... If I have to... I'd rather avoid compression onto plastic, so I'd use a pushfit coupler.

Either or IMO - Both are suitable.

Also depends where it's going to end up - compression shouldn't really be used where it's inaccessible, though, that being said ... should push fit? Not sure that question's ever really been answered.

Apart from gas, I don't think there's any rule about inaccessible mechanical joints. Just best practice really, which nobody seems to follow at install... And when encountering a failure in a void, all one can do is replace with another mechanical fitting!

I'm sure we were taught when when doing our level 2, not to use compression fittings anywhere where they weren't accessible, not just on gas. Maybe it's a legacy things then or I just dreamt it

Need to see if I can find any info.

I think it depends on the quality of the 10mm pipe tbh.
If it's dented/marked then surely a compression would be better?
That's just my thinking.
It is easily accessible.

I'm just converting two 10mm rad connections that are constantly getting hit when hoovering and cleaning.
It's endless leaks.

Want to convert them to pushfit amd bring them up in centre of rad and use angled adapters into TRV/LS.

Probably sink them in as well so no chance of leaks.

The usual approach to that would be to take 15mm tails up out of the floor - use 10mm to 15mm reducers in the floor and then 15mm copper straight up into the valves.
