I have a condensing tankless water heater install in a room adjacent to a bathroom. The acidic condensate will flow from the water heater through a 3/4” pipe through a condensate neutralizer becoming a neutral condensate. It will continue on inside a 3/4” pipe towards the a 2” shower tailpiece. See picture. However, before the 3/4” drain goes through the reducer and get to the shower tailpipe, I would like to find some sort of 3/4” PVC device fitting that will provide an air gap so that the condensate forming in the 3/4” tube can flow past an air gap and into another 3/4” PVC tube until it finally discharges through a reducer (pictured) and shower tail pipe.
Does anyone know if such an 3/4” air gap device exists?
