Aquascape Compact Water Fill Valve

The Aquascape Compact Water Fill Valve automatically maintains water levels while protecting pond, aquarium, and pool pumps from running dry which can lead to pump damage or failure. Better for pond ecosystems as it adds small amounts of water as needed, eliminating large water chemistry swings that occur during top-offs, including chlorine and chloramine levels. It fills up 1.5 gallons per minute (0 - 100 PSI), and includes adapters for 1/2" PVC, 1/4" and 1/2" poly, and a 3/4" standard garden hose.
