when water level returns to normal.If the water alarm valve or solenoid is stuck closed, incomingwaterwill not be
allowed
toentertheBubble‐Up®JrInteractive™maintank.Thiswillcausethetanktoemptyandthelowwaterfloatto
turnoffthepumptoprotectitfromrunningdry.Ifthewellpumpfailstherewillbenowaterenteringthemaintankof
