I am hesitant to share this but figured I would get some feedback. I will not name any names as we are still in the process of figuring out the issue.
-Had a 17k gallon fiberglass pool installed at the start of summer and went great all summer. we truly loved the pool and enjoyed it (although a cool summer cut short the fun)
-Just these past two months we noticed a small crack running across the coping (we did not put in a deck, just grass up to the coping they poured). I did not think anything of it for as we all know if you pour concrete it will crack.
-about a week ago wife thought raccoon had been in pool. black scratches on the first step. but then we noticed more on the next and on the bottom of the deep end following curve of the pool. I thought must be spider web cracks I have read of.
-fast forward to this last week, came home to a pool where the water level had dropped about 3 inches. I though ok maybe evaporation? so I filled it again, same thing the next day.
-decided to let it run its course and let it run down skimmer. it ran to bottom of skimmer and kept dropping. so I called installer and let him know. he said most likley a jet leak, cracked fitting etc. whew, good thing no deck, easy to get to.
-let it keep dropping and it went below all returns and now below led lights as well. it has since dropped 2 inches below led. there are no other holes/drains etc below this point. only shell.
-somehow we have a hole/crack/leak in the shell. builder says in his over 300 pool installs he has never had this.
-not sure what next step is, they are coming tomorrow to locate leak but not sure if they will decide to replace shell or want to repair. I think they will call manufacturer but i fear they will want to repair and I doubt integrity of that if it has already leaked once.
I know there are plenty of fiberglass haters on here and this will only reinforce it but I think it is still a fine type of pool I just suspect there was either some error in the manufacture process or the install. (near the spot of the cracks they had put a strap to straighten one side of the pool (it is rectangle) and put pressure to straighten it and backfill and pour coping) I really am at a loss. Not mad at anyone at this point but interested to see which direction this goes.
