Cast Iron Soil Pipe Installation Instructions

Use a tape measure to determine the distance that the new pipe has to span. This is the distance between the two pipes that you are installing the new pipe between.

Measure the same distance from one end of the soil pipe and make a mark there. Do this several more times, all around the pipe. Connect the dots into a line that runs all around the pipe.

Hold the pipe in a C-clamp. Cut into it with a hacksaw all around the line. Once the pipe is deeply scored, remove it from the clamp and set it on the ground. Insert a chisel into the groove that you scored and strike it sharply with a hammer. Cast iron is relatively brittle, and this should cause the pipe to shear off at the line you scored. If it does not, put it back into the clamp and work on it some more with the hacksaw.

Slip a rubber collar onto each end of the pipe that you are installing. Slide both collars all the way down onto the pipe.

Widen two collar clamps so they are wider than the pipes. To widen the clamps, turn the screws of the tightening bands counterclockwise with a screwdriver.

Slide one collar band over the free end of one of the pipes to which you're attaching the new pipe. Slide the other collar band over the free end of the other pipe that you're attaching the new pipe to.

Position the new pipe in between the other two. Slide the rubber sleeves over the joints so that half of each sleeve is on one pipe and half is on the adjacent pipe.

Slip the collar clamps over the rubber sleeves. Tighten the clamps so that they bite into the rubber sleeves by turning the screws clockwise. The pipe installation is now complete.
