I am replacing a 14 ft piece of cast iron Drain that goes between my 2nd floor, 1st floor and basement schedule 40 4 in cellular core PVC. The Drain runs along the ceiling of my basement into a wall and out to the sewer. So, how do I vertically support the new PVC between floors? I know riser clamps could be used with cast iron but what do you use to support PVC?
