Need help installing our pool ladder that attaches to the deck. We tore down our existing pool and put a new one and built a deck all around the pool. Now we are re-installing the pool ladder and cannot remember how it was previously installed. Does anyone have experience on installing this type of ladder? Seems as if the bottom of the ladder hovers over the pool bottom without touching it? Would it hit the pool sides when people are stepping in and out on it? We are about to mount the cups that hold the ladder on to the deck and want to make sure we do this correctly.
