One of the connections behind the convenience center, as mentioned above, is the likely culprit. I took the wall off in the basement and had to tighten all of the connections on the hoses. Every one of them was loose. While I was at it, I chased all of the hoses and had to tighten most of them. I even removed the panel for access to the shower connections and they were not tight either.
If you remove the wall in the basement, reattach it with industrial strenght Velcro, and not the screws. You will thank your self every time you need to go behind it again, and you will. Did that to mine 6 years ago and the wall is just as tight now as it was before I removed the screws.
