tap change for electric unvented hot water cylinder

by Simon H » Sat Oct 27, 2018 4:24 pm

Hi

I have an electric unvented hot water cylinder in the loft. I want to change the washer in the hot tap on the ground floor. Do I simply turn off the mains and then run the hot tap down? Then after washer change simply turn back on the mains? I'm unsure about pressure and air bubbles etc...
