I'm really not sure how they work as opposed to the larger diameter size since I only have that one size. Just looking at the picture on agselects website, the 'Edstrom Original Drinking Valve, 1/8"mpt connection, all brass' does look like the screw end is smaller in diameter then the ones that I have

I haven't bought any though so I don't know for sure, I was just told about it through a PM. I guess the main reason for my post was to warn people to double check the sizes before they drill all the holes and cement it all together. The old carpenters adage, 'measure twice, cut once' works for more then just lumber.
That is a LOT cheaper, especially when you're buying in quantities. Thanks for the link
I suppose I will eventually sell the old rat rack when I get the new rat rack finished. I'll have to disassemble it to get it out of my basement, though it shouldn't be hard to reassemble with a cordless drill. The current rat rack also doesn't have automatic watering like the mouse rack does (another reason I'm building a new one) rather it uses a bunch of recycled whiskey bottles with sipper tubes for water so it looks kind of ghettoWorks pretty well though. I wouldn't want to sell it outside of the Minneapolis/St Paul area either because it would be more expensive then it's worth to ship. It would pretty much be a 'you buy it, you haul it' type of deal. But like I said, that probably won't be happening until spring time anyway. If you want more info on it please PM me because I don't want to clutter up this thread with sales talk.
