I have a mini split in a bedroom that was set up so the condensed water drains via a plastic hose into 5 gallon bucket in the cellar. There is no proper drainage in the cellar so periodically I have to carry the bucket up the stairs and dump it out.
This is getting old fast especially when someone in the house leaves the window open with the AC on! Grr.
Would it be possible to drain the water into the soil pipe instead? Adjacent to the bucket is the soil pipe with a trap and jim caps similar to photo below.
Perhaps I could replace the cap on the house side with, say, a 2 foot tall pipe and fit the hose into that? I'm thinking it needs a length of pipe so backups don't overflow -- I've seen something similar in use in clothes washers in basements I believe.
Edit to add: The mini split is in a bedroom on the ground floor, one floor above the cellar. The mini split is mounted on an interior wall and there is not easy route to the outside.
Suggestions for other approaches are most welcome.
