Auto Fill Mini Float Valve 1/2" – Automatic Water Level Control

Compact Inside/Outside-Mount Float Valve for Hands-Free Reservoir Refilling

πŸ’§ Always Free Shipping on All Products β€” No Hidden Costs!

Never hand-refill again. The Auto Fill Mini Float Valve 1/2" connects to a standard 1/2" water line (like a braided toilet refill line) and automatically maintains your water level so your mist maker keeps running smoothly. Its compact body mounts inside or outside the reservoir and has no external moving parts, so it won't interfere with your foggers. (Tip: use a 1/2" adapter to switch to whatever line size you need.)
