Is gate valve necessary in sewage ejector discharge pipe?
Posted by MarkDIY on December 12, 2003 at 08:52:32:
I'm installing a sewage ejector. I've got a check valve that will pass 2" solids. I've seen in drawings that a gate or ball valve should be inserted above the check valve. Is this necessary? Will it typically still pass code without it? Any thoughts are appreciated.
