The only thing I worry about is will they all always have access to water? I mean, is it possible for there to end up being air in a line somewhere that's going to cause me grief? Any tips and tricks you can share about the installation and initial usage? I've read a few DIYs on how to put one in, just looking for the experience of people who have been there and done that for any special stuff.
Sorry it took so long to get back to you. The installation is pretty easy. You should follow the DIY threads. I actually used this website: http://www.arbreptiles.com/cages/rat_rack/ratrack.shtml to build my rat breeding racks, and run the gravity-fed water systems.

Each time you fill the buckets, you should test each nozzle to make sure water is coming out. If the water line ever goes below the hole in the bucket, you will have air in the line, so never let your bucket get that low. One issue that has happened to me twice is flooding. Each time the rats bit the plastic tubing, and the water flooded their tubs. It killed all of the rats in the tub. Make sure that it is impossible for the rats to get to the tubing. I believe that the newly designed nozzles heads are larger, so only part of the nozzle fits into the hardware cloth, so you should not have this issue.

Hope this helps, and if you have any questions feel free to PM me.
