Hello - I have a rough-in that was put in when the house was built in 1999. Help because I don't know what all the pipes are for. I have one coming out right next to the wall, I have one that I am pretty sure is a tiolet pipe, a square box cut in the floor with stones in it with one pipe in that, a pipe that is right next to the box and then a big sumpump looking hole with a cap on it next to that. What is all this stuff?
Thanks in advance, Shawn
