Hi all, I opened my pool a week ago with no issues. Yesterday, I thought the water level looked a little low, but chalked it up to the frequent back washes. This morning, however, I'm sure something is wrong. I turned on the pump manually and was greeted with a lot of air blasting out of the returns for about 15 seconds. Everything went back to normal after that. The water level is about 1/4 inch below yesterdays even with about the same amount of rain. I'm guessing something in a skimmer line has cracked. Is there anywhere else I should look?
