15mm isolation valve

[Stu Thompson]

Hi.
I have to replace the taps on a small sink. Currently the tails fit onto the hot and cold-water supplies into a female end fitting.
I want to add isolation valves to both supplies but all these seem to come with compression ends.
My question is - can I just remove the compression bits (the olive obviously and the male ' nut) and just screw the valves male end into the female end connector on my supply pipe?

God I hope this makes sense.

Thanks
Stu

Probably not, but post a photo and we’ll be able to tell you for definite- and also suggest an appropriate solution 😊

A lot of plumbers do that yes but I'm not a big fan

I've seen some fail because the rubbers get a little nick in them so either file the compression end a little to remove a bit of the sharpness or you can buy flat faces ones or connect a male iron after the valve.
