I have been using regular chlorine bleach for sanitizer in my pool from the beginning-which is only 4 years now. This spring my pool lost all it's water and after taking off the cover I found a 4" horizontal tear at the bottom where the seam is. I repaired the seam and waited a couple of days to rehang the liner since the wind decided to blow it off. While hanging the liner I ran across another 18" rip right on the seam and I was wondering if the pool store knew I was using bleach if they would still cover the seam separation? Does using regular liquid bleach nullify warranties?
