Hi everyone. I have been reading these forums since my pool was built six years ago. Thanks to all the good advice here, I have always had sparkling water and have never had any major problems...until now. I recently noticed that the interior wall of one of my skimmers is bulging and rust is developing in that spot. I suspect that it may be due to the cracking between my coping and deck. I have attached pictures to show what the problem is. Can anyone advise me on what I will need to do? I fear a major repair job in my future.
