Abstract: In swimming pools the pop-up cleaning nozzles threaded into walls in the pool bottom are removable by a rotatable tool that has a body with axially extending lugs which project into corresponding openings in the nozzle head. A vacuum cup centrally of and recessed into the body attaches to the nozzle head for removing or replacing it.

Abstract: A rotational indexing nozzle arrangement has been devised wherein positive and consistent indexing action takes place under the influence of the application of fluid pressure and its relief by the action of an indexing or biased spring which becomes relaxed during the first stage (outward) movement of the indexing of the rotational nozzle head and which bites in and holds thereby causing the nozzle head to rotate during the second stage (inward) movement of the discharge head. The extent of the incremental indexing is determined by the length and angle of the biasing spring, or member. For improved operation a bearing of the ball or roller type may be disposed at the inward end of the nozzle arrangement whereby the resistance of the closing spring to rotation of the nozzle head is lessened.

Abstract: A fluid routing device has a sealed self-contained body which includes all of the working parts of such a device is combined with a base plate having discharge ports which register with outlets in the sealed body which are controlled by valves within that body, means for sealingly, but releasably, attaching the base plate to the body and the body to the conduit to a source of fluid under pressure are also included. The disclosure also teaches a method of servicing devices in a swimming pool system including the steps of providing in the device a sealed self-contained releasable body portion containing the moving parts, removing a malfunctioning sealed body portion and replacing it with a new functioning sealed body portion.
