Can someone please explain the difference between an isolating valve and a service valve. Which one should I use for an electric shower, and are the speedfit ones suitable? Thanks

In principle, they serve the same purpose, but what is usually referred to as a service valve is a small inconspicuous valve that is turned on and off with a screwdriver and an isolator is a larger valve with a handle (either a gate valve or stop tap).

Electric showers can use either a stop tap or service vale.

Hi,

They are the same thing, yes if its for a shower it will be fine if its a full flow valve.

Hth

Thanks for the replies. :D

use a full-bore isolator valve (the handle type) as this will give a better flow rate to the shower.
