Well I’ve just found out a plumber has been doing it for years.Not directly no.
I can get thousands of those olives from work.The problem with using speed fit/flexi pipes and such isolators is that there is a little washer that gets crushed when you connect up to as it relies on compression to reduce the diameter at the fitting, it’s great for fit and forget but rubbish if your ever planning on removing again in the future as the washer is a one time use only and needs replacing when you do any work. You are better off using the proper speed fit isolators and or swapping to copper pipework.
I’m aware of these but you’re missing the point. I can’t have them because my flexi’s are nut fitting because the China tap doesn’t have room to accommodate my posh expensive speed fit flexis.https://www.screwfix.com/p/jg-speed...V4ejtCh3RJwGZEAQYASABEgKcHPD_BwE&gclsrc=aw.ds
15mm diameter but you can also get 12 and 10mm. They are pricey but much higher quality and the valve is unlikely to stick.
If you prefer plastic then these are the suitable ones https://www.screwfix.com/p/jg-speedfit-15svp-isolating-valve-15mm/12372
Yes I have pipe inserts.Yes with pipe inserts to support the barrier pipe. BUT those taps are cheap and nasty, and Flexi pipes on mains pressure is a no from me!
There are inserts in the speed fit part. As far as I can tell the CP 15 I posted above will lose one end & fit the flexi pictured & the the other end will compress the olive onto the plastic with no dramas. And only 95 pence or grab two from work.Speedfit used to supply rigid plastic internal sleeves to reinforce the plastic pipe against crushing when it transitioned to brass compression fittings. I have no idea if they still do. I'm not a big fan of plastic plumbing. It can get you out of a tight corner but it looks sloppy. It probably fits in well with the rest of the workmanship on a modern domestic building site.
Edit: I was referring to semi-rigid plastic Speedfit pipe, not flexible hose.
