I am currently having issues with my ASF rack, a few of the tubs keep flooding their bedding with the water from the water bottles.

My rack is the one from this DIY: http://www.arbreptiles.com/cages/rat_rack/ratrack.shtml

I haven't piped the water system because I dont have space for a bucket on top, which causes issues with the gravity feed, so I am using water bottles, I have switched between a few different kinds of bottles (glass, plastic, large and small) and a couple of tubs just keep draining the bottles.

Anyone else experience this? Have any suggestions?
