Thanks. My first thought on the blue ones only filling up a bit. I think that may be better as the water would change out. If they , blue ones, are from Minnesota I like that brand. We just ordered 2 new heated ones
Well, poop. Wish I had read your comment before I went to the rabbitry. LOL ..
Since I like to tinker, and my time is worth nothing, I decided to fix the blue ones so they filled more. They work on a small spring, when the water fills the bowl, the weight of the bowl compresses the spring and presses a silicone stopper onto the water supply.
So, the spring was too weak. It allowed the bowl to fall with only a little weight. I stretched the spring a bit, and now the bowl fills about 1/2-3/4.
I'm of two minds about this - (well, I'm of two minds about virtually everything, so really not worth mentioning) Heat is the largest factor in Texas, so I want to make sure there will be enough volume of water for multiple rabbits (although only one can drink at a time? so maybe not an issue?)
I can see where having the bowl refresh more often is desirable, too.
Which brings up the downsides of these.
1) Occasionally poop gets in the bowl, (probably because of a bad location, so that may be able to be avoided)
2) If there is any debris in the water supply I think it could block the small silicone stopper and allow it to leak all the water out.
3) if you have a weird rabbit that must like to be wet, they will lay under it thereby pushing the bowl up so it never stops filling and have it drain completely out.
So, although I really like the idea of a bowl, I would not use it if I couldn't check at least daily to make sure there is sufficient water or if you could hook it to a permanent water supply. When I go away for a day, I hang the old water bottles in addition so I don't worry.
