ABSTRACT:
A water softener drain adapter system includes a tube having a first end and a lumen, a plurality of air slots project into the tube, an arcuate cap encloses an end of the tube opposite of the first end, and a tapered barb connector tube projects through the cap into the lumen. The tapered barb connector tube is for coupling to the drain hose of the water softener, and the first end of the tube engages the drain pipe within the sewage system. The plurality of air slots prevent sewage from being siphoned back into the water softener thereby preventing the water softener from being contaminated.
