Though I do not have your TT. The pump will usually be located on the other side of the water connections. In my Bullet that is beside the bed where I remove 4 screws from the top of the "night stand" and there is the pump. You can turn on the pump and locate it by the sound but if it is not working that will not help. They are almost always easy to access and behind a panel where you have to remove screws. Hope that helps.
