Tapping Valve Sacrifice?
Tapping Valve Sacrifice?
(OP)
I was once told by a senior engineer that when you install a tapping sleeve and valve to hot tap a force main, you have to install another valve, like a plug valve, because you have to sacrifice the tapping valve. I can't remember why? Any ideas?
