         21 . A system for delivering a quantity of chemicals into a toilet bowl comprising:
 a chemical container having at least two chambers, a first of the at least two chambers configured to have chemicals to be delivered to the toilet bowl disposed therein;   an electric pump having a pump inlet and and a pump outlet, the pump inlet in fluid communication with the first chamber, the electric pump pumping chemicals from the first chamber container through the pump inlet to the pump outlet and into the overflow tube during every filling of the toilet bowl.   
     
     
         22 . The system according to  claim 21 , wherein the electric pump is disposed in a second chamber. 
     
     
         23 . The system according to  claim 21 , wherein the electric pump has a fluid sensing switch in electrical communication therewith to sense the location of water filling a water tank associated with the toilet bowl. 
     
     
         24 . The system according to  claim 21 , wherein the electric pump is in fluid communication with an intermediate container, the intermediate container is in fluid communication with the chemical container and the fluid passes through the intermediate container. 
     
     
         25 . The system according to  claim 24 , wherein the intermediate container is a tube. 
     
     
         26 . The system according to  claim 21 , wherein the pump is in communication with the chemical container by a tube. 
     
     
         27 . The system according to  claim 21 , further comprising an adjustable switch, the adjustable switch in electrical communication with the electric pump, the adjustable switch regulating the amount of fluid pumped from the inlet to the outlet 
     
     
         28 . The system according to  claim 23 , wherein the fluid sensing switch is disposed outside of the first and second chambers. 
     
     
         29 . The system according to  claim 21 , wherein the pump inlet is in the first chamber. 
     
     
         30 . A system for delivering a quantity of chemicals into a toilet bowl comprising:
 a chemical container having chemicals to be delivered to the toilet bowl;   an electric pump having a pump inlet and a pump outlet;   a fluid sensing switch in electrical communication with the electric pump; and   a chamber in which the electric pump is disposed, the pump outlet in fluid communication with the chemical container, the electric pump pumping fluid from the pump inlet disposed within the chamber to the pump outlet and into the chemical container to cause chemicals to flow into the toilet bowl through the overflow tube during the filling of the toilet bowl upon receiving a signal from the fluid sensing switch, the fluid sensing switch being disposed external to the chamber.
