  3. Plug the pump into a GFCI electrical outlet.
  4. Place the collection cup on the skimmer.

  1. Disconnect the pump from the electrical outlet.
  2. Remove the skimmer from the sump.
  3. Remove all the water from the skimmer body.
  4. Remove the venturi tube and air control valve and run water through the unit so that water runs through air control valve.
  5. Remove the impeller well cover, impeller and shaft. Clean well. A small amount of vinegar should be used to clean the ceramic shaft.
  6. With a small brush clean the inside of the impeller well.
  7. Reassemble and install back into the sump.

If sponge clogs, the water level in the skimmer will increase causing the skimmer to collect foam/water in the collection cup. Clean twice a month and replace when needed.

Clean as needed. Keeping the collection cup clean insures a properly operating skimmer.
