ABSTRACT:
A simple winterizing/maintenance process which enables the pool owner to take samples of a swimming pool water, analyze it, and add the appropriate chemicals to the pool during the wintertime off-season months when it is covered and out of normal service. A device has been designed to distribute chemicals throughout a pool and provide the necessary mixing action to assure homogeneity of the water and chemicals. This entire process is performed with the pool cover in place and the main pool pump and filtration system out of operation. The need to winterize the pool or lift the cover at any time during the off-season is eliminated.
