Head for in-floor pool cleaning system

摘要

A cleaning head for an in-floor pool cleaning system includes a sleeve with a top opening and an insert configured to be retained within the sleeve. The insert has a first body portion with an aperture wherein the first body portion is configured to fit through the top opening, and a second body portion that is configured to not fit through the top opening. A passage runs through the insert to the aperture. The insert has a first position in which it is retained in the sleeve. When water pressure is applied to the bottom of the cleaning head, the insert is moved upward to a second position so the aperture extends beyond the top opening in the sleeve and pressurized water exists the aperture to move debris. The cleaning head also includes a conical spring to bias the insert towards the first position.
