I performed the bucket test and found I am losing 1/2 an inch of water a day (15k gallon fiberglass pool). It appears to lose water the most at night after the pump is off (added water in the morning and did not notice any water loss in the evening). From search of previous threads, I may be losing water from a leak at the skimmer? Below are pictures I took near the basket. It appears the old seal has deteriorated and even missing in some areas. Next I turned off the pump. When the water was still, I squirted some red food color near the holes at the edge of the basket missing the seal. Didn't see the food coloring get sucked in. The food coloring just stayed suspended in the water. Any suggestions? Thanks in advance.
