my showerhead drips constantly.
how do I isolate the shower so that I can replace the washer without draining the hot water system ?

Absolutly correct!! Get a plumber or risk a floos! I'm a plumber and there are a few things we can do to speed up the process.

you really need to call a plumber, no isolation valves will require a system drain down, but the plumber may know some tricks of the trade to avoid this, don't risk flooding your house !
if the plumber needs parts, try www.showerspares.com or call 0845 126 4141
