Happy New Year All, Does anybody have a suggestion for a ballast venting valve for a soft tank ( my ferro structure ) that is around 1 1/2" diameter or maybe 2" , I will most likely use a stainless ball valve but I'm worried that eventually it is going to sieze up on me. It seems like those ball valves get awfully hard to turn after a while. The butterfly valves that I've seen ( for farm irrigation ) seem to turn easier , but I haven't seen them in stainless. Thanks Brian, Ventura, CA
