So I recently had my pool redone from the coping down. I saw the tile guy meticulously go over the spillways in the spa, checking for level between the two spillways and shaping the outer grout line by hand. So I am not saying that they didn't take the care with my pool that I would want. However, the spillways used to, ever so slightly, overhang the pool which caused the water to waterfall into the pool. The way they did it is to make them just like the rest of the wall between pool and spa with no flat outer edge and maybe even a slight downward angle to them. The result is that with a brand new clean filter and max flow, one of them just barely manages to waterfall and the other, which seems to be slightly off level from side to side, just barely manages to waterfall on one side. My major concern is that if the water goes straight down the side it will cause more issues with the tile there than normal and that it may wear out the plaster below far quicker than the rest of the pool. Am I wrong? Or should I call them and ask them to fix it?
