Fill-O-Matic 2000 Automatic Pool Water Leveler
Best overall: 2,243 ratings with only 4% at one or two stars, sold on Amazon by the Texas company that makes it — The Fill-O-Matic 2000 sits on the deck on a rubber base and feeds a float valve you slide to the level you want, 2 to 9 inches below the deck. Owners give it 4.6★ across 2,243, and only 4% of those ratings sit at one or two stars. DesignStein, the San Angelo, Texas company that makes it, sells it on Amazon itself. The catch: its instruction sheet says that above 60 psi a pressure reducing valve must be used, and that if it fails to shut off, "the water pressure is most likely too high". Its newest critical reviews describe units that would not shut off, one at 25 psi with a new washer, and a plastic hose thread that cracked. The warranty is one year, with a lifetime base.

Pros
- Only 4% of its 2,243 ratings sit at one or two stars

- Of its 10 newest written critical reviews, 3 describe a leveler that would not shut off (one at 25 psi with a new washer, still adding water through 2 inches of rain), 2 a plastic hose connection that cracked, at 7 months and at 2 years, and 1 a unit so light it floated without added weight; the newest says the maker would not replace a defective one
- The float's rubber seal has to be turned every 3 to 6 months, and one owner says the unit has to be taken apart to do it
- The maker's own terms say it "may malfunction, become obstructed, leak, deteriorate, or fail to stop water flow" and "is not a water-leak detection system"
