Has anyone used these valves?

Hey Rich, thanks for the post! I will definitively be needing valves. I'll give your new ones a shot. I'll probably be ordering about 100 late December.

Thanks so much for the post/update. Try you best to keep your sanity! :-)

I added you on fb :)

Sanity was gone a long, long time ago.

I just started using these last weekend and they work fine on both mice and rats. This being my first auto water system its hard for me to tell you the pros/cons of the different valves on the market but none of my animals are having problems with them.
