Alright. Yes there is water in the tank. Filled! So, for those who have been helping me here is what I came up with. No drainage from tank. Weird right? So, I decided to take my small hose adapter squirter madingy, and shoot up thru the drain. And voila! We have drainage! Went inside the coach with hose, and opened valves from antifreeze kit and blew water into tank. Turned the pump on, and again voila! We have water with pressure!
