Turned water on over the weekend,
and heard that awful sound nobody wants to hear after they think they've covered
all the bases last fall..it's in the wall going to my cowboy shower that's in
the first stall. Is this an expensive fix? I can't find any screws,
all pop rivets. And no access from underneath. This is a weekender
4-star. Any guesses for the repair cost, I'm in Kentucky?
