Title: Valterra twist on valve
Review: I have cable operated valves and my black tank valve leaks. I attached this valve between the trailer and the sewer hose and am able to prevent the black tank from leaking the liquid waste which leaves the solids behind thus creating buildup issues. Works very well. Now I can decide whether I want to even hassle with opening up the enclosed bottom of my rig and attempting a repair of the cable operated valves (which I hear eventually fail again later).
Is the review positive or negative?
