Does anyone know what kind of valve that is (i.e. what make)? I have two of the same type on my DC and they are in bad shape. I would like to use the same type for mounting purposes. I recently replaced all my pumps, similar layout as the photos. Not easy, not alot of space to work in...The valve for the fish boxes is located on the bilge floor near the transom. Very difficult to reach in and rotate handle. I wish this was in a smarter location...
