Need to know if you have a system to repair slow leak in the ring. It's been fine for months and now has a slow leak in the air ring.4'x15' pool. This is my second pool. The first had a factory defect. Looks like a small air bubble weakened the plastic. I spent a year trying to patch it, finally had to get rid of it. Because the pandemic and a shortage, the second pool cost me almost $800. Now I have another slow leak.
