Note
Waste connections or the drain outlet shall be designed and constructed to provide
connection to the sanitary waste system through an air-gap of 2 pipe diameters or
50.8 mm (2"), whichever is larger.
Caution
Never insert the drain line directly into a drain, sewer line or trap. Always allow an air gap
between the drain line and the wastewater to prevent the possibility of sewage being back-
siphoned into the softener.
