Diagnosing where the leak was wasn’t that bad. I manually shut off the pump, and listened for sucking sounds. The sounds and the little bit of water I found helped me determine that the leak was coming from jandy valve.

Jandy Valve

First to come off was the hand tighten nut on top of the handle. A crescent wrench made this easy.

The handle could now come off revealing the bolts fastening the top piece.

Next was removing the screws holding the jandy’s top piece on.

Screws Removed

With the screws removed, a flat headed screwdriver was used to evenly pry the top off.

The fairly simple valve mechanism is revealed once the top is removed.

It didn’t take much to see there was a problem with the o-ring in the jandy valve, it was broken.

The new o-ring cost me $7 at the local pool supply store. I also went to Ace Hardware and bought the missing 4 bolts for $2. Installation was just the reverse of disassembly.
