Black Tank Dump Valve

Hello, I have a 2009 Jayco Designer 5th wheel model RLTS and can not get the black tank dump valve to close completely. I know where the dump valve is located and my question is do I have to cut a section out of the 4 season floor to reach this valve? Has anyone else had this problem and is there a better way?

    On a previous trailer, using a box cutter, I cut an access opening into the Coroplast under belly panel.... replaced the valve, and resealed using the piece of Coroplast that I removed and Gorilla Tape...

    tip: make sure the black tank is empty before you remove the old valve....:E
