Anti-siphon joker valve

I'm looking for a small 1/2" joker valve for my vented loop on my Lehman. Have been unable to get through to ADC yet.

I've never seen a vent like that, but it looks like a very good one. If you can't find the joker valve and need to replace it, I suggest you use one made by Scot pumps. It looks like yours has a 1/8" male pipe thread so the Scot 109-13-VB-18 should work. http://www.scotpumpmarine.com/CN/CN-10913.pdf

Just re read your post, if the thread is 1/2" ignore the above.

Forespar also makes replacement duck bills for their units. You may get lucky.

Forespar MF-841 Replacement Duck Bill / Cap Assembly

If not, you may have to replace the entire loop.
