Hey everyone, I am currently working on making my sump pumps discharge run more efficient. I have two pumps and a pretty high water table. They currently discharge by the side of my house and then the discharged water then runs down the driveway and pools at the driveway basin. No good.My first step will be installing a brand new check valve on both. One has a very old one and the other one didn't have one at all. So hopefully that will help a lot with the frequency of how much they currently run.Second, I am going to extend them out, across the driveway and out about 20 feet into a dead and unused area of our yard where water has never pooled during rain. The asphalt driveway already had a channel cut across it from what I could best guess was a dish tv hoop up so that part was made a whole lot easier for me.First big question is, would it be safe to run both lines into one when I start to pitch downhill? Or just run both lines side by side? They are both inch and a half. Could I run them into a 2inch and not lose flow?Second, how should I end the run? I am in New Jersey so freezing temps are a concern in the winter. Someone told me just use a 90 degree pop up fitting at the end and leave the top right at ground level. Others have said to keep the end of the run underground.If I keep it underground what is the best way to set that up to avoid water pooling in the area or backing back up into the lines?Or do you think the pumps will have enough force to push the water through a 90 at the end with a pop up attachment?Thanks DIY, im fairly new at this but I am all aboard on doing it myself and doing the grunt work. Just looking for the absolute best approach. via /r/DIY https://ift.tt/2THMn8x
