I'm thinking about finishing my basement but at the bottom of my stairs the plumber installed a very strange setup for my sump pump. See attached picture.
Ive never seen this before so I wanted to know if I could shorten this. My neighborhood is on a hill/rise and the house is about in the middle. There's a collection pond at the bottom.
Edit: the PVC pipe is connected to the storm drain on the left and to the sump pump in the pit on the right. I want to make this setup smaller by shortening the black pvc pipe from the ceiling to the floor. I don't even know why this setup is necessary since it's connected to a storm drain. This is in my basement which is underground.
