Sump pump drain pipe with 2 opening ?
My sump pump drain pipe has two opening. The first one is located right next to the foundation wall as you can see from the picture. Yesterday it was raining a lot and I saw a lot of water gushing out of this opening. About the other 30% were flowing into the the lower opening. Why does someone put PVC wye on the draingage pipe? I think some water will return back sump pit if the water discharge thru the first opening. My pump was running every few minutes yesterday. Can I just cap it off?
