Automatic poultry watering system - You don't need to drill holes in the bucket, that kind of work is annoying. You only need to connect our products to Sch40 1/2inch pvc pipe. Superior quality - The real high-quality material is very sturdy, and it is difficult to break. Nipple and Tee can be perfectly matched, they are connected by threads, of course, you can also separate them. About Leak - If the water pressure is high, PVC glue is required for the connection between PVC Tee fittings and 1/2inch pvc pipe. (All connections between PVC pipes require PVC glue when they reach a certain water pressure.) The threaded connection between the nipple and PVC Tee fitting will not leak. colour:White+red Material:Plastic, metal Package Contents: 10 set x poultry waterer Only the above package content, other products are not included.
