Hi, I have an issue with my water softener/iron filter backwash lines. I am on a septic tank and my WS/filter are in the basement .I want to splice a wye adapter into the drain to install a p trap but code dictates a 18" standpipe. The 3" drain is hung from the floor joists as in the picture and one photo shows that I have 14" from the pipe to the floor , so am I euchered, or is there a way around this? At the moment I drain both machines into my sump but living up here in Ontario I have freezing problems come winter.
