I thought someone in this thread may have a urine-diverting toilet and could help. Our 6 year old Separett Villa has a clogged urine line. I had been trying to keep it clear with white vinegar sometimes, and biokleen enzyme cleaner foam spray sometimes, and of course water, and recently it was so slow I tried hydrogen pperoxide, which seems to have loosened so much material that it clogged it. Following on the advice from Separett we used drano as the last resort... And I don't think this slope and diameter of line is meant for that, nor probably for letting it sit overnight because it wasn't working... For now it is fully fully clogged without even a slow drain. Sadly we've built around it over the years and I can't fathom how to get it out to be able to directly poke at the connection of the "back" end of the urine line to the pipe in the wall (goes to buried grey-only field) so I"m hoping to next siphon out the line (drano, vinegar, water) to get boilng water directly onto the backmost, probably clogged area.
Has anyone with a toilet like this had this problem?
