Patent ID: 8689369

Claim:
A swimming pool skimmer for use with a swimming pool comprising: a housing having an intake that receives water from the swimming pool, a filtration chamber containing a strainer, the intake being in fluid communication with the strainer, positioned downstream from the intake; a plenum that is in fluid communication with the housing and returns pressurized water from a pump to the swimming pool; a treatment system that includes a disinfectant chamber, which is configured to contain a treatment medium to condition the water, the disinfectant chamber configured to discharge conditioned water into the filtration chamber, the disinfectant chamber and filtration chamber separated by a generally vertical wall, the wall including a generally vertical slit to allow water from within the disinfectant chamber to pass to the filtration chamber; a flow-control valve that is configured to adjust the flow of untreated water entering the disinfectant chamber wherein adjusting the valve to a first position causes the water level in the disinfectant chamber to rise, which increases the amount of water in contact with the treatment medium, and causes a first flowrate of water to exit the slit, and adjusting the valve to a second position causes the water level in the disinfectant chamber to drop, which decreases the amount of water in contact with the treatment medium, and causes a second flowrate of water to exit the slit that is less than the first flowrate of water, wherein the flow-control valve includes a tubular housing and a rotary dial having indicia.
