WATER PRESSURE IS SHOWN AS DIAGRAMMATIC ONLY. CONTRACTOR SHALL VERIFY <br />EXISTING WATER PRESSURE IN FIELD PRIOR TO ANY WORK AND PIPING ROUGH IN. IF <br />DISCOVERED ON SITE THAT EXISTING WATER PRESSURE IS LESS THAN 68 PSI, CONTACT <br />ENGINEER IMMEDIATELY FOR PIPING DESIGN CHANGES. IF PRESSURE IS GREATER THAN 80 <br />PSI PROVIDE PRESSURE REDUCING VALVE AND REDUCE DOWN TO 77 PSI. <br />PRIOR TO WORK VERIFY INCOMING WATER QUALITY TO SPACE. WHEN INCOMING WATER IS <br />ABOVE 3.5 GRAINS PER GALLON (60 PARTS PER MILLION) SCALE BUILD-UP WILL FORM INSIDE <br />THE PLUMBING SYSTEM CAUSING DAMAGE TO SYSTEM COMPONENTS AND COPPER PIPE. <br />TO AVOID DAMAGE DUE TO SCALE BUILD-UP, EITHER A WATER SOFTENER OR ANTI-SCALE <br />DEVICE SHOULD BE INSTALLED AT POINT-OF-ENTRY. APPLICATIONS WHERE THERE IS A <br />CONCERN FOR WATER SPOTS ON GLASS SHOWER DOORS, GLASS DISHES, VEHICLES IN <br />CARWASHES, ETC., AND/OR THE EFFECTS OF HARD WATER ON HUMAN SKIN, A WATER <br />SOFTENER SHOULD BE USED INSTEAD OF AN ANTI-SCALE DEVICE. ANTI-SCALE DEVICES <br />REDUCE THE FORMATION OF SCALE IN A PLUMBING SYSTEM BUT DO NOT REMOVE THE <br />CALCIUM AND MAGNESIUM FROM THE WATER, WHICH WILL REMAIN ONCE THE WATER HAS <br />EVAPORATE LEAVING WATER SPOTS AND/OR DRYING OUT HUMAN SKIN. WATER <br />SOFTENERS REMOVE CALCIUM AND MAGNESIUM FROM THE WATER BUT REQUIRE ROUTINE <br />REFILLING OF SALT LEVELS IN THE BRINE TANK. <br />EXISTING WATER SERVICE CONDITIONS NOTE: <br /> NOTE: <br />INSTALL 1" BACKFLOW PREVENTION <br />DEVICE FOR DOMESTIC PURPOSES <br />PER STANDARD PLAN NO. 1432 <br />OVEN <br />RACK <br />CE <br />L <br />L <br />O <br />CE <br />L <br />L <br />O <br />OVEN <br />RACK <br />OVEN <br />RACK <br />OVEN <br />RACK <br />OVEN <br />RACK <br />MI <br />C <br />R <br />O <br />RE <br />F <br />CWS CWS CWS <br />RPZBFP <br />PLUMBING SITE PLAN PLAN1 <br />P-100.1 SCALE: 1/4" = 1'-0" <br />(EX)1" WATER METER DEDICATED TO NBC <br />(EX) WATER MAIN <br />M <br />DOMESTIC COLD WATER SERVICE SHOWN IS BASED ON BEST AVAILABLE <br />INFORMATION AND IS AN APPROXIMATE LOCATION.
