installing a p-valve on WP EX2.

[gentlegrunt]

I’m looking for a p valve for my waterproof EX2. It has an extra port on the hip. I know it is not a normal place for p valve. However, sitech advertises that Triton p valve fits any sitech valve. All the valves on EX2 are sitech. I disassembled the hip valve and noticed that the original rubber sitting looks slightly different than the one comes with the trigon valve, a little bigger to be precise. So I am wondering if trigon p valve is gonna fit.

The front thigh pockets do not really leave enough space for the normal position for p-valve, which is above the knee and towards the inside. Thanks for sharing any experience/methods.
