Can you give us a pic of where the leak is on the Jandy valve? This is on the suction side valve?I switched the main pump to just “spa” since the spa is still full until the pool finishes filling. When doing this I noticed the Jandy valve has a leak out of the bottom. This is keeping the main pump from fully priming. How urgent is this? Like “DO IT NOW” or ”get it done this week?”
Will the leak prevent your pump form getting water when turned on by freeze protect?
It is probably an O ring leaking. You need an O ring Kit and some Pool Lube. Check that you get the cover O ring size for the size valve you have.
