Stetson Float Valves are the most reliable essential feature for swimming pools, fountains, ponds, and other water features. With its durable ABS construction and adjustable arm, you can be sure our water leveler will always provide superior reliability. Stetson Float Valves are easy to use when installing into Pouralid Water Level Systems or other water features. You always want to use Teflon tape on the threads and wrap the tape around the threaded nipple 5 to 6 times, then the float will thread into the water feature. To tighten it up, you can wrap it up in a rag and tighten. The hood scoop on the valve should face down with the float arm coming out and up. Loosen the wing nut by using your finger to lift the float arm up into the off position and set the float bottle to the 8:00 or 9:oo o'clock position. After filling stops, you may need to lower or raise the float to the desired water level and tighten the wing nut.
