I think every rabbit breeder is visited by thoughts about the possibility of automating the process of care and feeding, but if everything is much simpler and more understandable with feeding, then the situation with drinking water is a bit more complicated (or at first it seemed to me).
The main requirements of the car drinker were as follows:
- Great battery life
- System Reliability (Animals cannot flip or chew)
- Drinking water should always be clean
- Minimal interference with the drinker
- Minimum issue price
At rabbit breeders car drinkers from plastic bottles are very popular, but I immediately rejected this idea. It may be good if you plan to breed 30-40 rabbits. But if the bill goes to hundreds, and in each cell it will be necessary to remove the bottle, fill it with water and install it again, automation turns out to be dubious. So I decided to install a large tank, and already dilute the water from it with a propylene pipe. No sooner said than done!
The system worked for a year, and showed itself only on the positive side. There is one minus. with the onset of frosts, you have to turn off that part of the car drinkers that are on the street. To do this, there is a tap, install the bath and twice a day go around all the cells with a bucket of warm water. But part of the cells and mother liquors are located in a room where the temperature, even in the most severe frosts, does not drop below zero, there the drinkers work all year round.
He placed water tanks on top of the cells that are in the room, and used plastic containers of 150 liters. For 150-200 rabbits in the heat of one refueling is enough for an average of two to three days. In my case, refueling from the water supply is in manual mode, but you can install a float from the toilet tank, and the system will turn out to be fully automatic.
The length of the pipeline from the water tank to the last tap, which serves to air the system upon first start-up and drain the water before frost, is about 60 meters. With this pipe diameter length of 20 mm, it’s enough, even in the summer heat, when almost all drinkers work at the same time, one rabbit replaces another. And which is important for the year of operation, the rabbits did not gnaw a single pipe, they did not like propylene.
In the photo the system is still in winter mode, the drain cock is open.
I used nipple drinkers only metal, which screwed directly into the plastic plug of the polypropylene pipe. To do this, a hole with a diameter slightly smaller than the thread on a nipple drinker was drilled in the already soldered plug and screwed without any additional sealants.
