The Aquascape Water Fill Valve 200 automatically adds water to your water feature when needed. Once set at the desired level, the reliable mechanical arm-style fill valve will help to reduce time spent filling your pond, fountain, or Pondless Waterfall. Automatically topping off your feature will help to protect your pump from running dry in the case of water loss. The slow addition of water also helps to contribute to a healthy ecosystem by preventing large chemistry swings associated with adding large amounts of water at one time. The Fill Valve’s small size and ability to handle up to 3 gallons per minute flow rate (up to 100 PSI) allows the valve to be installed into a wide variety of water feature applications. Includes fittings to connect to ½“ poly-pipe and ½” PVC. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
