It is a 12v electronic waste valve for use on RV black and gray waste tank

Does this valve have a prvovision to operate manually like the Valterra EZ? Valterra don't make a 11/2 inch and don't have room for bushings.

yes my 1.5" needed 2 longer screws to attach the mounting plate size 10 -32 1.5" the 3' did not need any extras
