Near the end of last season, I mistakenly shut the Jandy valve before turning off the pump (Hayward "Super Pump") which resulted in a big shudder as everything locked up for a moment. I quickly reopened the valve, but evidently caused a seal to break as I started getting air bubbles coming out of the return. Was hoping the situation would magically heal itself over the winter, but no such luck.
Yesterday, I sealed the connections between the pump and Jandy with Lexel, but no improvement. Any thoughts on other areas -- between the Jandy and the pump -- that might have been damaged by the jolt I created.
