I want to install a utility sink that is in my garage in the basement (walk out). The main problem I have is although the previous owners had water lines put into the garage, I can't determine what the 2" pipe next to the water lines is. I had a plumber come today thinking it would be an easy determination. We ran all of the water all over the house, but nothing came down the pipe. He said he would need to cut the pipe and run a camera down to make sure it attaches to the septic and isn't a vent line. The cost to do that and install the sink (if the line indeed is a drain) would be $1500! I'm a fairly handy woman that has no problem doing my own plumbing work so I feel that if this is a drain line I can do this work.
I'm attaching a picture of the water lines and the pipe. If this pipe is a vent pipe would it actually go into the ground? I feel like this pipe was probably run specifically for this sink when the house was built, but how do I verify this without spending $500 to scope?
