Abstract

A preferred embodiment method for dispensing a product ( 121 ) such as cyanuric acid into an existing swimming pool circulation system includes providing a product ( 121 ) placed within a permeable bag ( 120 ). The permeable bag ( 120 ) containing the product ( 121 ) is placed into a cavity ( 104 ) of a flood feeder ( 100 ) having an inlet ( 105 ) and an outlet ( 108 ). The inlet ( 105 ) and the outlet ( 108 ) are in fluid communication with the cavity ( 104 ) of the feeder ( 100 ). A diluent is supplied to the inlet ( 105 ) and the diluent is allowed to flood the cavity ( 104 ) thereby contacting the permeable bag ( 120 ) and dissolving a portion of the product ( 121 ) to create a use solution within the cavity ( 104 ). The use solution is allowed to exit the cavity ( 104 ) through the outlet ( 108 ) and to flow into the swimming pool.

Claims (47)

1. A method of dispensing cyanuric acid into a swimming pool, comprising:

providing a chemical consisting of cyanuric acid;

providing a permeable bag into which said cyanuric acid is placed;

placing said permeable bag containing said cyanuric acid into a cavity of a feeder having an inlet and an outlet, said inlet and said outlet being in fluid communication with said cavity;

supplying water to said inlet and allowing said water to flood said cavity thereby dissolving a portion of said cyanuric acid to create a use solution, said inlet regulating an amount of water flowing into said cavity; and

allowing said use solution to exit said cavity through said outlet and flow into a swimming pool, said outlet regulating an amount of use solution flowing out of said cavity.

2. The method of claim 1 , wherein said cyanuric acid is dispensed from said outlet at a rate of approximately 0.5 to 8.0 gallons per minute.

3. The method of claim 1 , wherein said cyanuric acid, said permeable bag, and said feeder have a dispensing rate of approximately 0.20 to 1.40 pounds of cyanuric acid per hour.

4. The method of claim 1 , the swimming pool having a circulation system with a pump and a heater, wherein said inlet is installed after the pump and said outlet is installed after the heater, whereby said feeder is in fluid communication with the circulation system.

5. A method of dispensing cyanuric acid into a swimming pool, comprising:

providing a chemical consisting of cyanuric acid;

providing a feeder having a water inlet, a cavity, and a use solution outlet, said water inlet and said use solution outlet being in fluid communication with said cavity;

placing a permeable member between said cyanuric acid and said use solution outlet, wherein said permeable member prevents said cyanuric acid from exiting said cavity through said use solution outlet;

placing said cyanuric acid in said cavity;

supplying water to said water inlet, said water inlet regulating an amount of water entering said cavity, wherein said water enters said cavity and dissolves a portion of said cyanuric acid thereby creating a use solution; and

allowing said use solution to exit said cavity through said use solution outlet and flowing into the swimming pool, said use solution outlet regulating an amount of use solution exiting said cavity.

6. The method of claim 5 , wherein said permeable member is a bag containing said cyanuric acid.

7. The method of claim 5 , wherein said permeable member is a mesh member covering said use solution outlet.

8. The method of claim 5 , the swimming pool having a circulation system with a pump and a heater, wherein said inlet is installed after the pump and said outlet is installed after the heater, whereby said feeder is in fluid communication with the circulation system.

9. A method of stabilizing chlorine dispensed with a dispenser in a swimming pool, comprising:

placing a chemical consisting of cyanuric acid into a cavity of a container having an inlet and an outlet, said inlet and said outlet being in fluid communication with said cavity;

supplying said container with a diluent, said inlet regulating an amount of diluent entering said cavity, said diluent entering said cavity via said inlet and dissolving a portion of said cyanuric acid thereby creating a use solution;

allowing said use solution to exit said cavity via said outlet, said outlet regulating an amount of use solution exiting said cavity; and

dispensing said use solution into the swimming pool, wherein said cyanuric acid stabilizes the chlorine in the swimming pool, said container reducing an occurrence of cyanuric acid block in the swimming pool.

10. The method of claim 9 , further comprising placing a permeable member between said cyanuric acid and said outlet, said permeable member preventing cyanuric acid that has not been dissolved into said use solution from exiting said cavity through said outlet.

11. The method of claim 10 , wherein said permeable member is a bag containing said cyanuric acid.

12. The method of claim 10 , wherein said permeable member is a mesh member covering said outlet.

13. The method of claim 9 , further comprising:

connecting said inlet of said container to a first conduit interconnecting a pump and a filter of an existing circulation system of the swimming pool;

connecting said outlet of said container to a second conduit after a heater of said existing circulation system of the swimming pool; and

allowing water from said existing circulation system to be routed into said cavity to create said use solution which is then dispensed into the swimming pool.

14. A method of stabilizing chlorine dispensed with a dispenser in a swimming pool, the swimming pool including a circulation system having a water pump, a filter, and a heater, comprising:

providing a feeder having an inlet, a cavity, and an outlet;

connecting said inlet to the circulation system between the water pump and the filter with a first conduit;

connecting said outlet to the circulation system after the heater with a second conduit;

placing a chemical consisting of cyanuric acid into said cavity of said feeder;

providing means for preventing said cyanuric acid from flowing out of said outlet in a solid form;

flooding said cavity with water received from the circulation system via said inlet, said inlet regulating an amount of water entering said cavity;

dissolving a portion of said cyanuric acid thereby creating a use solution;

allowing said use solution to exit said outlet, said outlet regulating an amount of use solution exiting said cavity; and

routing said use solution into the swimming pool, said feeder reducing an occurrence of cyanuric acid block in the swimming pool.

15. The method of claim 14 , wherein the means for preventing said cyanuric acid from flowing out of said outlet in solid form is a permeable bag containing said cyanuric acid.

16. The method of claim 14 , wherein the means for preventing said cyanuric acid from flowing out of said outlet in solid form is a permeable member placed over said outlet.

17. The method of claim 1 , wherein said permeable bag containing said cyanuric acid is replaced with a new permeable bag containing cyanuric acid when said cyanuric acid has been depleted from said permeable bag.

18. The method of claim 6 , wherein said bag containing said cyanuric acid may be replaced with a new bag containing cyanuric acid when said cyanuric acid has been depleted from said bag.

19. The method of claim 11 , wherein said bag containing said cyanuric acid may be replaced with a new bag containing cyanuric acid when said cyanuric acid has been depleted from said bag.

20. The method of claim 15 , wherein said permeable bag may be replaced with a new permeable bag containing cyanuric acid when said cyanuric acid has been depleted from said permeable bag.
