ABSTRACT:
The filter tubes of a swimming pool filter are cleaned by a spray nozzle connected to a high pressure water source and carried on the end of a wand adapted to be inserted slidably through the drain valve and moved back and forth to cause the spray nozzle to traverse back and forth beneath the tubes. Dirty water from the filter is discharged around the wand and through the drain valve.
