Air gap intake and heater hoses

If I had Photoshop maybe I could have put a pair of tits on it. Everyone likes tits!

LOL, agree w/ that. What most people don`t realize is, that pipe sizes "are" the inside diameter of said fitting or pipe. I don`t think I`d run a 1/4" m.i.p. x 1/2" hose barb fitting on anything tho!
