if i fill one side of my kitchen sink (double bowl) with water and turn on the disposal when I drain the water some water comes up into the other bowl. If I dont run the disposal water doesnt come up into the other bowl. Also during normal use water doesnt come into the other side. Only when I test the drain with the disposal running with about 2 gallons of water in the bowl it comes up the other bowl drain. Is this normal?
