
Everysixmonths:
• Checktheoperationofthefloat,pumpcontrol,solenoidvalve,andtheblowerbyturningonawatertapand
allowingittorun.Atfirst,thewaterwillbesuppliedbythe2.1gallonwaterexpansiontank,andthenthepump
shouldturnon.A
fewminuteslater,youshouldheartheblowerstartandthesolenoidvalveshouldopen.(The
unitcannotremoveradonunlesstheblowerisworking.)
• Checktheincomingflowrateonthemetercontrol.Typicalwellpumpfillratesarebetween4and7GPM.
Higherflowratesystemsare
available.
