I have a 2014 Aliner Expedition with bathroom and integrated (inside) shower. The shower fixture leaks! If the water for the shower is off, there is no leak even with the water pump on. If the water for the shower is on, it leaks a little bit from behind the fixture. If the water for the shower is on, but turned off at the head (the sprayer at the end of the hose), it sprays water. So, I think the leak is between the knobs and the shower head, but from behind somewhere. I'm having a hard time figuring out how to get to the fixture - I can't reach it from underneath where the hoses go in, and I don't know / can't figure out how to remove it. Does anyone know if you can remove the shower fixture without having to tear apart the whole thing? Thanks!
