TheDrainWaterPipingfigureaboveillustrates
therecommendedpipingtoafloorsanitary
sewerhubortrenchdrain.Thetwovertical
pipedropsshoulddrainwaterthroughan
indirectwaterconnectionwithan“AirGap”.
Codeauthoritieshavingjurisdictionmaydictate
otherindirectwaterconnectionrequirements.
Thefiguredepicts
