We just came back from 2 week vacation to find the water level on our recently completed pool had risen to the top of the tile. I drained some weather today and then inspected the auto fill valve, which has developed a crack and is leaking (see picture.) I'm worried that the only way for the builder to properly repair this will be to saw through the pool deck, which opens another can of worms. I'm not sure if the white plastic is PVC or not, but if so, I was thinking that they could pry the crack open slightly and put some PVC glue or epoxy in it, and then tighten a metal hose clamp around it to hold glued pieces together. Thoughts?
