Hello
I need to replace a broken monoblock mixer kitchen tap. The only working isolation is on the rising main.
The hot water valve under the combi is solidly open.
If I shut off the rising main, switch off the boiler, then open all of the taps to release any residual water, will that be ok for me to then change the kitchen mixer?
By not being able to shut off the hot at the boiler, would I risk an airlock when I open the rising main valve upon completion?
