Manual Override & Included Parts
Tool-free manual override: the E40B-8 valve can be opened manually if 12V power is unavailable. The exact-part installation instructions describe withdrawing the actuator pin, turning the handle 90 degrees and pulling to open the gate; use the provided manufacturer procedure when servicing.
The complete kit includes the electric 3-inch hub-to-hub valve, a 1-foot valve harness, a 7-foot switch harness, an illuminated switch, black- and gray-water switch faceplates, valve seals, fasteners and installation instructions. Valterra's electrical specification is a 12V DC 2.5A motor with resettable 5A breaker. ABS solvent cement is not included. If plumbing connections must be adapted to a different size, those adapters are sold separately.
