I’m replacing my water filtering and softener system. The only drain we have in the basement is connected to the sewer pipe. The drain line for the old system are T’ed together and connected to the sewer line using an air gap connector.
However, the company of the new system said that the drain lines should not be T’ed together. So I need to add 2 more drain lines to the sewer pipe. There are also 3 other drain lines draining into the same place (1 from our AC unit, 2 others from dehumidifiers). So I need a setup that can accommodate 6 drain lines at the same time. I tried the setup in the picture below, and failed miserably…😅 water was splashing out everywhere when the filtering system was regenerating. Please help me figure out what’s the proper way to do this. I’m very confused… especially about the airgap requirement.
