description An overfill-prevention valve system includes a testing mechanism, operable by a user from the inlet end of the drop tube, which can be used to verify proper valve function without actually filling the storage tank. The testing mechanism allows the user to actuate the valve manually using a test probe, such as by elevating a float to simulate a full storage tank. The testing mechanism may be located upstream of the valve to facilitate the testing operation without interfering with the valve body. The mechanism may further provide non-contact functionality, such as with magnetic actuators on either side of the drop tube wall, to eliminate a potential test mechanism leak points. The test probe used to actuate the test mechanism may be shaped to define a desired rotational position at the test location within the drop tube, ensuring proper rotational alignment of the magnetic actuators.
