Abstract

A testable overfill prevention valve ('TOPV') for a liquid storage container. The TOPV allows an individual to readily verify the operability of the TOPV. Preferably, a test member of directly contacts a portion of a latch to release a flow control member so that the flow control member can move from an open position to a closed position wherein in the closed position liquid is generally prevented from flowing out the TOPV. The test member preferably directly contacts the flow control member to move the control member to an intermediate position between open and closed positions allowing an individual looking down into the TOPV to see that the flow control member has moved sufficiently to confirm operability of the TOPV. Preferably, the test member is spring biased to a non-testing position and the entire test member is disposed in the housing of the TOPV when in a testing position.
