Pool owners and farmers, this 1/2 inch float ball valve makes water management so much easier! Made from durable brass with a plastic float ball, this valve automatically maintains water levels without any power required. The adjustable arm lets you set the perfect water height for your needs, and the 1/2 inch NPT pipe thread connects easily to standard plumbing.

Perfect for livestock troughs, pools, ponds, aquariums, and water tanks. The gear design on the adjustable arm provides stability, and the included rubber gasket ensures leak-free operation. Installation is straightforward - no special tools needed. Say goodbye to overflowing tanks and manual filling! This reliable valve works 24/7 to keep your water levels perfect, saving you time and preventing water waste. It's more adaptable than traditional metal float valves and built to last in various environments. Definitely a smart investment for anyone dealing with water systems!
