Oops. Read your PM wrong Tom. You are looking for a TU ball valve, not just a 1" union. Duh.
I'll have to check when I get home if I have another TU Ball Valve. I have a few on the 75G tank, so I'll have spares once I take that down, but I'm not sure what I have now. I think I used them all on the new setup.
BTW, I think Savko is about the best price to get these at. Thats where I got all mine. But a few months back, people were getting their CC numbers stolen when they ordered online at that site (it wasn't Savko doing it, someone else was hacking in or something). They probably fixed that problem by now, but to be safe, I'd call the order in. Dont do it online.
Or check UP Plastics. Didnt you say you had a discount code for them?
