Hi,

Just look under your boiler - a 15mm pipe poss next to hot outlet may have a blue tap/valve on it - close this and change away- reopen when finished - Simples!!

Turn off boiler. Close mains stopcock. Open kitchen tap to let pressure out. Work on tap. Open stopcock. Turn on boiler. Job done.

Cheers
