The valve I use to close one of the skimmers when vacuuming the pool seems to be stuck in the open position. The twist lock on top is loose but I can't get the handle to budge at all. The other skimmer and main drain valves are working normally. It worked fine when I vacuumed the pool last week.
It's a Jandy neverlube valve. Any ideas?
EDIT - Here's a pic of the plumbing. It's the second valve from the right.
