We have a water pond feature that requires constant attention to refill because of evaporation. The Little Giant Auto Fill Valve is perfect for the task of keeping the water level as it should be. At first I was dubious about how it would perform but after installation, and a little trouble with the included washer, it has performed perfectly for my needs. The only reason I chose 4 stars to rate this instead of 5 is because I'm not really in love with it, but I do consider it a worth while investment for the job at hand.
