First time using the flush, actually getting ready for the weekend and thought I’d use the flush connection to add 2 gal to black tank with the ol’ toilet tab. Heard good method on the way to the site for the blue water to slosh around on the way. Connected my hose and NO flow. Removed the hose and back pressure spray. Going back out to look in the pump bay to see if there’s a check valve backward.
