How to drain sump line out of house - cold climates.
Here is my situation. Any help would be greatly appreciated. My home has a sump line that drains into my septic system. I really don't like this setup, even though it has caused no issues, I worry it's a disaster waiting to happen. The sump line is 1.5". The main line out to the septic is about 4feet above the finished basement floor. I want to have the sump drain on it's own outside. The sump would have to pump vertically about 6 feet or so. How should I do this? I have about 70' from the front of the house to the drain ditch at the road. The lot slopes downhill the entire length of the lot from the house. I live in a cold climate in easter ONtario, and am worried of the line freezing in winter. I do notice some of the homes along the road with a drain line near the edge of the ditch that I assume are their sump drain lines.
Do I use flex piping, hard piping, how big, and do I worry about freezing?
Thanks for any help!
