14. RunOn–Watercontinuestodispenseoutoffaucetafterreleasingthe

Reason
“RunOn”or“CarryOn”ispresentinallWaterlogicpressurefedunitswithoutoutlet
Solenoids.

“RunOn”isdefinedistheamountofwaterthatcontinuestodispenseoutofthefaucetafter
releasingthedispensebutton.

RunOnexistsbecausethetankspressurizeaswaterisbeingdispensed.EveryWaterlogictank
hasanoutletrestrictortoensurethetanksremainfullofwaterandwateriscontrolledasitis
releasedtothefaucet.TheinletSolenoidcontrolsflowintothetanks.Thetankswill
“depressurize”oncethedispensebuttonisreleasedtheinletSolenoidcloses.Asmallamount
ofwaterwill“RunOn”throughthefaucetasthetankdepressurizestoatmospheric
conditions.

Typical“RunOn”is2‐3seconds.

“RunOn”canbereducedbyinstallingapressurelimitingdevice.
