Yeah I don't think I have ANY of them on mine.
Now I'm curious, I'll check it out when I leave work. Hopefully it'll still be light enough to see under it, but I think it's probably already getting dark. I don't see daylight much except on the weekends, when I mow yards
I was considering buying one of the aluminum ones from that guy on IC, would it replace all of those?
Let me know how you like that valve, I might get one if it's cheap.
