发明名称 Apparatus, system and method for use in backwashing pool filters
摘要 Apparatus for use in backwashing pool filters. The apparatus includes a resiliently-flexible backwash hose that tends to assume a flattened configuration when empty. A hose spool is provided having a frame having a frame handle, and a reel having a hub mounted for rotation on the frame. The reel includes two flanges extending radially outwardly from the hub, with the flanges being spaced apart to define a channel between the flanges for receiving the hose. A slot is provided in the hub for releasably receiving the end of the flexible hose to allow the hose to be wound on the hub when the reel is turned. A system and method of use, as well as an ornamental design, are also disclosed.
