Suction Lift:
Highpressurewaterfromthedrivepipepassesthroughtheventuriandpulls
waterfromthewellintotheejector,andthenpushesituptothepump.This
allowsustopushwateruptothepumpfromdepthsgreaterthan25feet,or
toboosttheoutputfromashallowwellpumptohigherpressures.

Pressure Switches:
Pressureswitchesareusedtocontrolpumpoperation.Theseswitcheshaveacut-inpressureandacut-outpressuretoturn

 Foot Valves:Whenpullingasuctionlift(shallowordeepwell)withtheBasicLineafootvalveisrequired.Thisvalve
 isinstalledattheendofthesuctionpipetopreventbackflow.TheMQwillalsobenefitfromtheuseofafootvalve

Theory:
 Matching consumption and pump capacity:
 Selectingtherightpumpisamatterofmatchingwaterconsumptionwithpumpcapacity.Installinganunderor
 oversizedpumpshouldbeavoided.Consumptionvariesgreatlydependingonhousingstandardsandlifestyle.Garden
 wateringinthesummercanincreaseconsumption.
Pump Selection:
 Pumpselectionisbasedonthewaterdemandandthesystemhead.Thewaterdemanddependsonthenumberof
 consumersconnectedtothesystem.HeadcaneitherbeexpressedinfeetorPSI.Headreferstostatichead,pressure
 head,andfrictionhead.ForassistanceinPumpSelectionrefertotheWebCAPSselectionprogramfoundonthe 

 andonthecost.PipingtakesintoaccountthesystemheadasreferredtoinPumpSelection.Staticheadisthedistance
 fromthegroundwaterleveltotheuppermosttap.Pressureheadisthesystempressurethecustomerwantstoachieve.
 Inmostresidentialapplicationthispressureisapproximately60PSI.Frictionheaddependsonthepipesize,typeand
