We Now Accept Recipient PUMPS AND CHLORINE  Facts and Figures Normal rotation speed of a pump motor is 3,450 rpm (revolutions per minute). On two speed pumps, the low speed rotates at 1,750 rpm. Alternating current (AC) in the United States runs on 60 hertz (cycles). In Europe and many other foreign countries it runs at 50 hertz. PVC plumbing is designed to carry water at temperatures of less than 100°F. CPVC plumbing is designed to carry water at temperatures above 100°F. HEAD CREATED BY VARIOUS PLUMBING AND EQUIPMENT COMPONENTS: A 1-1/2 inch x 90 degree elbow = 7.5 feet of straight 1-1/2 inch pipe A 2 inch x 90 degree elbow = 8.6 feet of straight 2 inch pipe A 1-1/2 inch x 45 degree elbow = 2.5 feet of straight 1-1/2 inch pipe A 2 inch x 45 degree elbow = 2.8 feet of straight 2 inch pipe Filters create 5 to 7 feet of head Heaters create 8 to 15 feet of head Facts and Figures (Continued) Sand filters strain particles as small as 60 microns Cartridge filters strain particles as small as 20 microns DE filters strain particles as small as 7 microns A 1 pound coffee can hold 1/2 pound of DE 1 pound of DE will coat 10 square feet of filter grid area Sand filters are designed to use #20 silica sand A heater pilot light creates 1,100°F of heat Electricity supplied to an electronic ignition pilot is 10,000 to 20,000 Volts. The chemical processes when chlorine (in any form) is added to water: Cl2 (chlorine) + H2O (water) = HCl (muriatic acid) + HOCl (hypochlorous acid) HOCl = H+ +OCl- (a positive ion of hydrogen and a negative ion of hypochlorite) at pH 7.2 = 80 percent killing HOCl + 20 percent useless OCl- at pH 8.0 = 20 percent killing HOCl + 80 percent useless OCl-   Urine and perspiration = ammonia One active swimmer produces approximately 1 quart of ammonia / hour. Liquid chlorine is sold in a solution of 10 to 15 percent strength.
