Hi, i have a run of 4 inch sched 40 from a tiolet/laundry area that will travel diagonally under the basement concrete floor a distance of 44 feet before reaching a cleanout. There is no opportunity to provide an intermediate cleanout other than to bring a combo riser to the surface somewhere in between and install a screw on cap or something. THIS WOULD BE OUT IN THE MIDDLE OF THE FLOOR WHICH I WOULD HAVE LIKED TO AVOID. Will this be necessary or will the 44 feet of pipe be ok? Or any other ideas?
