1) I am in NJ and am installing a basement bath with ejector pump. I was planning on placing a ball valve just after the check valve but was told by someone at the local box store who sounded intelligent that code does not permit a shut off valve in a waste line. Is this correct? I would like to have the ball valve there in case maintenance of the check valve is required and almost every drawing I see of basement pits show a ball or gate valve in line.
2) The check valve I purchased states to install horizontally, but most pictures and instructions show them mounted vertically. I can do either but wondered if it makes a difference.
background: The pit , rough plumbing under slab, and vent to roof were all done when the house was built and I am now finishing the basement. 2" abs lines for waste and vent.
Thanks in advance.
