Ok here is my problem I used to work for as Plumbing company in Queens and moved to Long Island NY Nassau county I am not sure about the difference of Plumbing codes. I am here to ask you a question. I have a main sewer cleanout in front of my home next to a fresh air vent coming out of the ground the clean out is in a 2 foot deep pit and the pit has a slate crappy cover someone can fall in. My question is can I open the cleanout and extend it above ground and cover the hole? Is this an old septic connection that was converted to a sewer system? I have some pictures if you like Click to Enlarge 79.4 KB Click to Enlarge 63.3 KB Click to Enlarge 47.19 KB Click to Enlarge 35.91 KB Click to Enlarge 30.35 KB Click to Enlarge 83.74 KB
