NOTE: Make sure the union washers are positioned properly
inside the union nuts and are not crimped.

Do not use excessive force when tightening unions or nuts.
Over-tightening and excessive force may cause leaks.

NOTE: A 3/4" (19 mm) hose or pipe may be connected to the
sump drain and run to an open sight drain. The sump
drain should not be permanently connected to the
sanitary drain system. Check local plumbing code for
proper drain installation. See the MAINTENANCE
