Removing Excess Water From a Swimming Pool

Removing debris and making sure the chemical content is balanced are not the only maintenance tasks you should routinely perform on swimming pool water. It is sometimes necessary to remove excess water from the pool, such as after a heavy rainfall or when you inadvertently overfill it. Use the specific method to remove the excess water that corresponds to the type of filter that is installed on the pool.

Submersible pump
Hose

Instructions

- 1
  Turn the pool pump off if you have a sand filter or Diatomaceous Earth filter.

  Turn the pump back on, and let it run for at least two minutes. Turn the pump off.

  Turn the filter valve to the rinse position. Turn the pump back on, leaving it on for between 10 to 30 seconds. Turn the pump off.

  Switch the filter valve to the filter position and close the backwash gate valve, if necessary. Turn the pump back on and check the water level. Repeat the process, if necessary. Pour Diatomaceous Earth powder into a pool skimmer, following the manufacturer's instructions for the filter size, if you have a DE filter.

  Follow the manufacturer's instructions to attach a hose, such as a garden hose, to a submersible pump. Submerge the pump into the swimming pool and discharge the excess water out of the pool. Do this if you have a cartridge filter, or even if you have a sand or DE filter.
