Fitting a sink with 10mm to 15mm (female) flexible tails - I am using pushfit pipe and connectors - is there a pushfit fitting on the market to convert the 15mm female to 15mm plastic? Or is it just a case of using a copper comp joint with plastic pipe? Is this OK - any drwbacks?
Copper Compression Fittings with plastic pipe??

Just put an insert in the plastic tighten up the nut of the compression fitting until you feel it bight, then 1/4 turn, fill with water, nip up as required a little at a time, no more than is necessarey to get it water tight.
I've used compression on Hep20, Hep2o push fit on Hep20, Hep2o push fit on copper, and Speedfit on copper.
All work well enough, but there's no single perfect solution for all circumstances - it all depends on the circumstances and the pressures involved.
To answer your first question, going from plastic tube to copper tube, personally I'd use push-fit if I wanted easy dismantling or if access with spanners was difficult, otherwise compression.

Yes it would leak.
Yes you can sometimes make them leak proof with compression, but I wouldn't promote the use of blemished plastic pipe at all.
Talking about plastic, interesting emergency yesterday, while people were away for 3 days plastic float valve in loft nut holding it together split clean in two, spat float valve off and full force mains blowing out (new estate, marvelous pressure) all weekend.
Looks like the house may have to be rebuilt, it's so badly built all the door frames have warped as well as the usual floors ceilings walls.
That's teach 'em to use plastic. needless to say I replaced it with a brass part II valve.

I left it with the customer in case his insurance company wanted to see it.
Funny thing this is the customer I gave an estimate for a condenser where I said it had to have vertical flue because of neighbouring boundaries. He was pulling in the final estimate last night apparently. No doubt he won't learn anything from this experience and will go with the cowboy who whacks a non steamer with standard flue straight into neighbours back yard like the last boiler.
I don't even care, but I won't fit it.
Anyway he's not in a very good mood at the moment so I didn't even discuss it.
