I have a 2017 Reflections 337RLS and the Black Water valve is getting very hard to open. It sticks about half way open and I really have to pull hard to get it all the way open. When I push it in after draining the black water tank it feels like it is pushing agains something and wants to spring back open. I have to keep it closed with a piece of wood cut to the right length otherwise I get a slow drain and there is no liquid left in my black water tank. I would appreciate any suggestions on how to make this smoother without dropping the underbelly.
Thanks
