Abstract
The invention addresses the problem of preventing a buildup of water conditioning chemicals in a swimming pool water circulation system in the event of a circulation system failure. The invention involves providing a control for the chemical regulation system which is responsive to the water pressure in the circulation system and determinative of the output of the chemical pumps of the chemical regulation system as a function of the pressure of water in the circulation system. The chemical injection pumps may be disabled when circulation pressure falls below a predetermined threshold, whether caused by power failure, mechanical pump failure, or obstruction of the intake pipe. Related apparatus, systems and methods are disclosed.
Claims7
Safety control apparatus for coupling to an existing swimming pool water circulation system with a chemical supply system for supplying both a sanitizing solution and a pH balance solution, comprising:
- a controller coupleable to the chemical supply system and the swimming pool water circulation system so as to turn off the chemical supply system when the pressure of water in the swimming pool water circulation system falls below a predetermined level, thereby preventing the supplying of sanitizing solution and pH balance solution;
- means for sensing the pressure of water in the swimming Pool water circulation system, the means for sensing comprising a tube;
- and
- ground-faulted means for electronically coupling the controller to the chemical supply system, whereby the safety control apparatus reduces a risk of injury to swimmers from chemical build-up in the swimming pool water circulation system after a period of poor or no water circulation.
A method for coupling safety control apparatus to an existing swimming pool water circulation system and chemical supply system in order to reduce a possibility of chemical build-up in the swimming pool water circulation system after a period of poor or no water circulation, the chemical supply system for supplying both a sanitizing solution and a pH balanced solution, the method comprising steps of:
- providing a controller which is coupleable to the existing swimming pool water circulation system and chemical supply system so as to turn off the existing chemical supply system when the pressure of water in the existing swimming pool water circulation system falls below a predetermined level, thereby preventing the supplying of the sanitizing solution and the pH balance solution;
- coupling a pressure sensing means comprising a tube between the controller and the existing swimming pool water circulation system such that the controller will be responsive to the pressure of water in the existing swimming pool water circulation system as indicated by a level of water in the tube when the controller is in an operative state;
- and
- electrically coupling the controller to the chemical supply system such that the controller turns off the existing chemical supply system when the pressure of water in the existing swimming pool water circulation system falls below the predetermined level.
