- Durable material: This automatic pig waterer with nipple is made of quality stainless steel, rust-proof, corrosion resistant and sturdy. - Water-saving and effort-saving: When pigs snout hits the water nipple, water flows out automatically and stops when their snout is away, so you don't have to keep refilling the bowl and the livestock can access fresh water whenever they like. - Easy to use and install: 2 holes at the bottom are convenient to attach this waterer to the wall (screws are not included); polished and curved edges for safety. - Product size and compatibility: Product size 8.27 inches diameter x 5.9 inches height; connect with 1/2 inch water hose; great for making a gravity fed system. Use scenarios: - In a commercial pig pen to provide continuous water with minimal maintenance. - In barn or outdoor pens as part of a gravity-fed watering system using a standard 1/2 inch hose. - In nursery or grower pens where wall mounting saves space and reduces water waste.
