Flexible Tap Hoses

[dougtsc]

I'm just changing some bath taps for a shower mixer. I have installed 22mm isolation valves into the hot and cold pipework. I intend to use flexible tap hose connectors from the isolation valves to the taps.
My question is this:
Screwfix sell hoses with a built in isolation valve and a bore of 13mm and hoses without an isolation valve but a bore of only 10mm. Should I go for the larger bore (I don't need the isolation valve) or will the smaller bore be ok?

Many thanks.

Depends on pressure available. Get 13mm to keep options open. You may find shower mixer doesn't work well - see current thread on this subject.

Thanks. Just found another website selling pipes with an internal bore of 19mm. Would these be better?

You could use plastic 22mm pipe. It doesn't burst by itself behind the bath panel, but is quite easy to use.
