The Sow Trainer Nipple is a special version of the Edstrom Sow Nipple. It has a stainless steel Trainer-screw built into the body. By turning in the Trainer-screw, the nipple can be set to drip slowly. This dripping water helps teach sows not accustomed to using nipple waterers to find the water source. The Sow Trainer must be operated on reduced water pressures of 15 - 20 psi. Once the sows have located and learned how to use the nipple, turn out the Drip Adjustment Screw to stop the dripping of water and return the nipple to normal function. 5 year Manufacturer's Warranty.
How it Works: To drink, the pig simply moves the stem by biting on it, releasing water. When the pig releases the end of the stem, the elasticity of the silicone rubber diaphragm located behind the stem head pushes the head back to the closed position, stopping the flow of water.
