No valve should be fitted on the outlet

Why can’t it be there ?

A full bore lever valve yes stopcock no bud

they both do the same job no difference in my eyes

Thats is why we are all different bud what one of us would do the other may not, I just prefer to use lever full bore valves on my installs and only stop cocks on a cold mains each to their own . Kop

It should be a full bore valve but noting says you can’t use a stopcock.

Have to agree with Shaun, there's nothing wrong with it being there - just not good practice. A stop tap is going to restrict the flow a lot more than a gate valve or full bore level/butterfly valve.

It's no different to a having a tap anywhere else on the distribution pipework. It will however potentially restrict flow more than a full-bore valve and reduce performance.
