An electrolytic pool chlorinator produces chlorinated pool water that is added to the cathode chamber to continuously dilute the caustic concentration of the catholyte before being returned to the pool. The cathode chamber includes a series of baffle plates between the primary cathode and the chlorinated pool water entry port in order to maintain the hydroxyl ion concentration near the primary cathode high enough to provide good current efficiency, yet low enough to avoid significant back-migration of hydroxyl ions. The baffle plates also cause metal hardness ions such as calcium to precipitate before reaching the primary cathode. A negatively-charged second cathode spaced apart from the primary cathode also helps to prevent precipitation of metal hardness ions upon the primary cathode. The chlorinator is provided with a feeder tank including a float-controlled valve having a leveraged flexible elongated seal that cooperates with a flared channel to regulate the flow of chlorinated pool water to the suction side of the pool pump. A catholyte access pipe extends from the upper portion of the chlorinator to the cathode chamber in the lowermost portion of the chlorinator to allow a user to flush water, acid, or brine therethrough. A thermostatic switch detects the stoppage of pool water flowing into the chlorinator and disconnects electrical power from both the chlorinator and the pool pump in response thereto. |
