Guess what, the Safety Valve is dripping !!regardless of what the book says you shouldnt use the prv as a drain
check its not dripping when you repressurise the system
TBH I have occasionally found small amount of water under safety valve area (1/4 of a cup) occasionally in past & wondered why CH pressure was dropping. Although I never saw it dripping in past.
Is there anything I can do to get it sealing properly ??
Should I just replace it ??
From Vokera manual it looks easy enough to replace, says to loosen grub screw at base & pull valve forward, replace in reverse order.
