Abstract: A plug manipulator tool for closing off the suction outlet of a skimmer of a swimming pool comprises a threaded hollow plug body having a cap resiliently held on the top thereof. The cap is provided with an elongated handle on the top surface thereof which enables the threaded plug to be remotely engaged within the threaded opening of the suction outlet of the skimmer by an operator twisting the outer end of the elongated handle. In order for the operator to remotely remove the plug while the circulating pump for the swimming pool is running, the operator tilts the upper end of the elongated handle to thereby tilt the cap so that water in the skimmer can flow into the hollow plug body and down through the suction outlet thereby breaking the suction holding the cap on the top of the hollow plug body.

Abstract: A tool for remotely manipulating an auxiliary cuff provided on the end of a flexible vacuum hose of a portable pool cleaner residing on the floor of a swimming pool. The tool comprises an elongated handle having its lower end pivotally held on the auxiliary cuff so that it lies against the flexible vacuum hose when in a storage position. By rotating the elongated handle so that it extends forwardly of the auxiliary cuff, the operator can insert the end of the handle into the inlet of the skimmer so that it extends out of the top opening thereof. Then, by holding the upper end of the handle the operator can remotely direct and insert the auxiliary cuff down into the suction outlet of the skimmer. The operator can then remotely remove the auxiliary cuff from the suction outlet by reversing the procedure.

Abstract: A tool comprising an elongated handle on the upper end of a driver member for remotely changing the rotational setting of a diverter valve mounted in the suction outlet of a skimmer for a swimming pool. The diverter valve is provided with an adapter ring having a protrusion on the top surface thereof. The driver member comprises a skirt with an upper hub portion. The skirt is provided with a slot on the bottom edge thereof and openings on the sidewall thereof. The hub portion has the elongated handle extending upwardly therefrom and an axial projection extending downwardly therefrom. While the circulating pump for the pool is running, the axial projection enables the skirt to be readily positioned and seated over the upper end portion of the diverter valve and the openings on the sidewall of the skirt enable the driver member to be removed from the diverter valve by permitting water in the skimmer to flow into the suction outlet thereof to break the suction.

Abstract: A free floating chlorine controlling assembly that continuously exposes a substantial quantity of a soluble agent to the water in a spa, hot tub, or pool, which agent may be one that tends to decrease the alkalinity of the water.
