Thanks Scott. I probably should have just tried searching under vortex. Anyway, after reading that it all seemed really simple until I saw the pictures. Basically you're just sticking a homemade flapper valve on the bottom of a piece of PVC pipe but to be noest I got a little confused about the need for two pieces of PVC and the o-rings. I'll have to take a better look at it after work.
