The float control of steam valves is the most sat-isfactory method of regulation, it the pump can be keptconstantly in use for this particular service. This require-ment can generally be arranged for. as there are only twowater services regularly needed for station use; boiler feedand general water supply, as shown in Figure 232-(H3-2).With the arrangement as shown the auxiliary main would beunder low pressure and would be connected with the pumpdischarging into the tank; in fact it would be supplied fromthe tank. It will be noted that the low-pressure main is inno way connected with other lines that at times carry highpressures. Thus the arrangement avoids the possibility ofwater under high pressure being let into the low-pressuresystem. The pumps are shown with each ha
