I have a Kenmore 370 Softener with a drain line that runs outside. Every winter I battle it freezing and need to do something this year to fix that. The softener is in the basement. I don't have any drains in the basement and I have a radon system so I don't want to cut into the floor to create one. My laundry is on the first floor, but is higher than the 8' the manual says I can go for the drain line. I was reading some other threads and saw something about increasing the diameter of the drain line to go higher than 8'. Is this true? I would have to go about 14' high in total to drain into the laundry waste pipe. It's also about 25' horizontal run to get from the softener to under the washer.
I was also thinking about a condensate pump based on other threads but am not exactly sure how they work. Does the softener drain go directly into the pump and then the pump to the laundry drain? Do you put it in a bucket? What would be the best approach?
