I'm installing a Flotec 1800LTS sump pump for use with a wet bar in my basement. The sump pump sits in a 10 gallon resevoir which when full, pumps out it's contents. I have connected the discharge line of the sump pump to the drainage line of the house. Is a seperate vent necessary for this sump pump, or is it part of the houses venting system now that it is connected to the drainage line? This pump is only going to be used for water and the occasional beer poured down the drain. Thanks for your help !
