After draining down a hot water system that up until now was working fine
to fit a new stainless sink in the kitchen, no hot water to any taps!
air lock? have tried opening all taps I have tried putting mains cold
water into the hot water system via a small length of hose pipe
between kitchen sink hot and cold drain cocks, no joy
