What 
                does "Vacuum to Waste" mean? 
              
When 
                you "Vacuum to Waste" you are pumping the debris you 
                vacuum out of the pool and sending the water to the waste line, 
                and not through the pool filter. 
              This method 
                removes a large amount of water from the pool in a short time 
                so be sure the pool is full before you begin. This method is used 
                for large amounts of debris and dirt. This method will only work 
                for circulation systems that use a 6-position filter valve. If 
                you have an older "Push-Pull" style filter valve you 
                must vacuum through the pool filter. Be sure to monitor the location 
                where the waste line is connected to the sewer system in your 
                home, just in case the sewer line cannot handle the large amount 
                of water and overflows.
