15mm pipe push fit to 1/2" male thread shut-off/isolato

[AlanB1976]

Hi all

I'm planning my first plumbing DIY job and have come across a stumbling block that I would have really thought wouldn't be this rare. Basically, I'm going from copper pipe to a new mixer tap (that was supplied with flexihoses ending in 1/2" female connectors). I also want to include a shut-off valve or isolator.
I see there is a shut-off unit available that is 15mm pipe push-fit one side with 3/4" male (for washing machines) on the other....but nothing for 1/2". It seems those flexible hoses with the tap is quite common so I would have thought they would have produced something for that market. So I have 3 options and I'm looking for any advice...
1 - Someone here tells me how stupid I've been and that the product (or simple alternative solution) is easily available.
2 - I go from copper pipe to shut-off valve (push fit) back to pipe to a new tap flexihose with push fit pipe adapter instead of the screw fit.
3 - I use the unit that ends with the 3/4" thread and get a 3/4" to 1/2" adapter to connect to the supplied flexihose tap adapter.

Any help would be great.
Thanks
Alan

Hi Alan, the female washered end of the flexi hose will fit on to a 15 mm isolation valve (compression fitting type).
Take off the nut and olive from one side of the valve, and screw on the female end of your flexi. Dont overtighten, (finger tight plus a 1/4 turn) so as not to damage washer.
The copper pipe fits on the compression end of the valve as normal.

No, don't do that. It's not designed to go onto compression with nut and olive removed.

You need to fit an isolation valve, then small section of pipe then a 15mm compression to half inch male copper to iron. Screw your flexi nuts onto that with a rubber washer pressed against the flat face of the copper to iron.
