Hey All,
I have a 2021 grand design 353g momentum. When I hook up a hose to the black tank flush I end up getting water on the floor in the kitchen. After chasing down the two black lines I found that they head up behind the shower wall to the check valve
How do you access this? I have tried the shower handles and there is no access behind those to see it. Where else could I get access?
