My mains stop cock leaks when closed or partly open, but never when fully open. I have tried tightening the packing gland nut, but it's as tight as I can get it.
All the advice I've found says close the stop cock before attempting to repack the gland, but this is when it does leak. Is this the correct advice for all types of stop cocks?
