We have a fiberglass pool that was installed last Fall. We used travertine tiles for coping and glass tiles as waterline tiles. I noticed some possible problems and the pool builder claims that the glass tile issue is normal and the travertine grout cracks can be fixed by simply filling them. I somewhat disagree with him and need your opinions to understand what is going on with the tiles.
Also, small bubbles come out of the return lines and there are bubbles in the pump basket. The pool builder said it is also normal and the bubbles are generated by the salt generator. What do you think?
Thanks in advance for your input.
