Air Leak Found, But Where?

[Texas Splash]

I always tell members that just because you don't see water leaking out doesn't mean there's not a leak. Today is a classic example. For the past couple weeks, when I would remove my pump lid with all valves closed, the water level would drop in the pot. I know that means air is getting in from somewhere. Today I decided to get knee deep into the pad. As I've told members here many times, take that 3-way valve apart. This is the valve on my pressure side. Surely water would squirt out if there was a bad o-ring right? Nope. I replaced that o-ring from the stem handle and all is good.
