I use an EdstromAutomatic Watering System and LOVE it. Out of all the rabbits I've had over the last 7 years, I've only had ONE stubborn Mini Rex, (who came from another breeder) ,that refused to learn to use it.
The nipples are solid brass with a central pin. When they press/bit/nibble/mouth the pin, water flows out. When they stop, it shuts off. The water stays clean and readily available. I have a 5 gallon bucket on top of each rack of cages... one bucket for 4 Flemish or 6 Mini Rex/Silver Fox. I use the Home Depot's orange buckets (with lids) because green algea won't grow in "red" light. (I use a "garden wand" to fill the buckets). I clean the buckets (with bleach) once a month. With the Flemish, 4 of them go through 5 gallons in 4-5 days.
I can usually tell pretty quickly if someone isn't drinking. First indication is the rabbit isn't eating (A thirsty rabbit won't eat.) If a rabbit isn't wating, the first thing I check is the water supply. Also, they tend to "prance" infront of the water nipple, letting me know that something is wrong. And I check the nipples and flow frequently. '
Momma rabbits teach their kits how to drink out of it... and 99.9% of the rabbits I've brought into my herd have adapted real well.
All that being said, it doesn't work well when the temperature dropsbelow 30F. So my winter water protocol involves crocks and carrying water to them 3 times a day.
