What type of isolating valve to electric shower.

[keith1944]

Hi all. I wish to fit the above into the 15mm supply pipe.
I have a 15mm ball valve but it looks quite restrictive in the centre and I don't want to lose water pressure.
I could use one of those lever ball valves or a standard brass gate valves.

any advice welcomed, thanks in advance. regards keith[/b]

A standard 15mm isolation valve is fine.
You shouldn't use gate valves on mains pressure.
