Hello,
I have only ever changed the washer on a cold tap before. I turned the stop-cock off and ran the tap until no more water came out, then I changed it.
In our new house we havea combination bolier, and I was wondering how you would change a washer on a HOT tap. Would turning the stop-cock off not cause the boiler to break by trying to heat fresh air, or does it work on pressure or something?
I would really appreciate a simple straight forward explaination, purely for my understanding.
Cheers.
