Whether your pond's water level drops from evaporation or a small unfound leak, an automatic waterfill valve will keep the water level topped off automatically. This will save you time and aggravation over having to worry about having to add or not to add water each day.
Automatic Waterfill Valves allow you to maintain fluid levels in your pond or water garden with exceptional accuracy. Fluid level forces the float to rise and close the diaphragm chamber, which expands to stop incoming flow.
Don't bother with trying to keep your pond filled to the proper level. Just sit back and let it fill itself as needed.
Garden hose adapters and water meters are also available for your water level monitoring needs.
