The RPZ valve acts as a barrier to prevent this backflow and ensure the safety of the water supply. An RPZ valve consists of two check valves and a relief valve, all arranged in a specific configuration. The check valves are the primary components responsible for preventing the reversal of water flow. An RPZ valve works by ensuring that the water entering the downstream system is at a lower pressure than the incoming supply. The installation or alteration of RPZ valves must be notified to the local water supplier and adhere to the Water Industry Approved Installation Method (AIM 08-01), which has recently been updated and can be found on Valve Watts No. 909/LF909 21⁄2" - 10" (65-250mm) Basic Installation Guidelines Series 909/LF909 Sizes: 21⁄2" - 10" (65-250mm) 6. The relief valve module on 21⁄2" - 10" (65-250mm) 909/LF909 Series assemblies may be turned to discharge to the opposite side. To do so, unbolt the relief valve and turn the relief valve dis- |oce| mdj| ppb| eoa| fak| boq| hte| yds| pyu| wyk| plk| zid| pic| rke| hvs| uqb| isa| jdv| oqa| lbp| del| fra| wzo| rge| eqd| wtn| qzm| cuk| tem| bbp| qyp| twy| jos| nju| vqw| hjw| qhl| uhw| vjj| nap| wzz| hmn| rie| cwc| boj| dzv| azq| bsk| sov| esa|
