The excess water will drain away and as you keep watching the water level, once you notice that the water level is halfway, or a bit from the base, then stop your filter pump and close your spigot.
  • The drain plug option: get your pool pump, then remove the PVC plug on the body, then turn on your pool plug. The excess water will begin to flow out of the pump drain plug.
  • Utility pump: attach a hose to the hose outlet on the pump, and put the other end of the hose in your drain area. Now lower the pump into the water. you will see how the pump will automatically come on after it has been connected to an outlet. Watch as water begins to gush out.
