IMPORTANT: This valve should only be used and properly
installed so that spillage of water could not cause damage. To
avoid water damage due to valve operation, a drain pipe must
be installed. It should terminate approximate 12" (305mm)
above a floor drain or through an air gap piped to a floor drain,
or other suitable place of disposal. Under no circumstances,
should the vent opening or drain line be plugged.
