I wasnt clear in my earlier post was about a twist on gate - (edited) My sewer connection and grey 2 under my sofa slide, So before the slide goes out , I connect the hose and open the twist on gate and grey 2 and leave them open till pack up. I only open the gates in the convenience center at flush / packup time. I tend to open and close the black handle a couple of times to get a good close but i havent got it where I trust it. I been behind the panel a couple of times and its wasnt the best organized area.
