Hey all-Recently I have been informed by my city public works that my sump pump draining into my sewer is against code and must be changed within 30 days. Knowing that the house AND sump pump existed before the sewer pipe I went searching for the old discharge. I have found one unexplained pipe that runs out my basement wall and halfway through my yard and because for some reason it is now attached to a water pipe(thinking someone had a fountain at one time)I know it is flushed and ready. My question is the pipe extending through the wall is 1" to 1 1/4" and it's flexible...Is it feasible for me to attempt to attach my 2 1/2" pvc coming out of my sump pump to this drainage hose??? Really can't afford a plumber right now and since I'm a city employee I can't really drag my feet on this...
