New to TFP and 2nd time pool owner - need help

Hey Everyone,

I wish I was here on a better note but we recently had a pool built and at 4 mos old we found a crack in the plaster. We've e-mailed the builder and he's said he is going to come out but it has been a month. I noticed the crack a month ago and immediately e-mailed the builder. The crack is about 14 inches long. It is very close to where the weep hole was in the gunite so the pool doesn't float before filling.

What are some of the options to fix a crack in plaster?

Pool specs
Chlorine pool, waterfall, slide, free form and about 15k gallons.

Thanks for any and all advice.
