OK, Just wanted to give a quick update to say that I have had NO issues with these RBI valves for the month 1.5 months or so that I've had them

I even ran one of the water totes empty last weekend due my crazy work schedule recently and had no issues with the RBI valves. Unfortunately I did have another flood in one of the last racks that I have not changed over to the new RBI valves

Needless to say I ended up buying more of the new RBI valves this week to replace the other valves. Please note that I have only used these with my rats and have not tried them with my mice yet. I am only a little hesitant to try with mice because these valves flow a lot more water if firmly pressed. Honestly, I'm not sure that the mice could apply quite that much pressure to be concerned..... Then again, I have never had an issue using Variflows with the mice either. I'm not really sure why but it was only the rats that seemed to "gum" up the Variflow valves.
