We have a 4-month old Sheer Descent waterfall that has a leak. Water is coming out along the top side of the fountain itself where it's mortared to the tile wall. The leak also appears on the back of the wall from the unit itself. Anyone have any comments about leaks with a Sheer Descent? I haven't found warranty information for it on the Jandy website and I have a call into them. I'm also working with our pool builder. Thanks for any suggestions.
