Bath Taps 22m advice needed

[Yorky1912]

I am changing over my old taps to new. The supply has 15mm to cold, 22mm to hot.

I am need to fit an isolation valve to the 15 and 22mm pipe..

I want to know how i connect the 22mm isolation to the 15mm tail on the hot tap.

I dont want to use solder if it can be helped.

Advice please.

Thanks
Lee
