Filling our new pool and it's been one thing after another. New thing is we have discovered a solid 4" section in one of the wall seams where it appears to have not been sealed at all. I used the two vinyl repair patches that came with the pool and that seems to have mainly fixed it but there is still definitely still a slight trickle. If I push inward on the exterior of the pool where the seam is, it stops the trickle. I was wondering if it's a good idea to use something like Flex Tape on the exterior of the pool around the seam to stop the trickle? Or should I use something else?
