Stop managing your water levels manually and upgrade to an automatic system built for consistency.
The FT150B Auto Fill Float Valve is a heavy-duty automatic water level control valve designed for homeowners and professionals who need accurate water regulation in in-ground pools, 8-inch autofill canisters, water tanks, spas, ponds, fountains, and livestock watering systems. It automatically opens when water drops and closes once the set level is reached—helping prevent overflow, underfill, and wasted water without requiring electricity or complex mechanisms.
One of the standout advantages of this valve is its large wingnut adjustment, allowing users to set the desired water level quickly and precisely. This makes it easy to achieve consistent fill height, reducing guesswork and saving time during setup or seasonal adjustments.
Designed specifically for pool autofill systems, the valve features 3/8″ NPT male threads and a 3″ arm, making it compatible with many standard 8″ canister autofill systems including MP, Super Pro, Pour-A-Lid, and Letro/Pentair installations.
Built for demanding environments, the valve uses corrosion-resistant Brass combined with stainless steel components to provide long-lasting durability in wet, chemical-exposed environments commonly found in pools, spas, and outdoor water systems.
The valve supports an adjustable flow rate up to 2.25 GPM, allowing controlled water replenishment while maintaining stable water levels in automatic fill systems.
With an overall length of approximately 7¼ inches, the valve is specifically designed to fit standard 8″ autofill canisters, making installation straightforward for most pool autofill setups.
Durable, reliable, and easy to adjust—this float valve provides dependable automatic water level control for a wide range of water management applications.
