Soil Pipe Repair Fitting

Updated February 21, 2017

Soil pipe, known also as sewer pipe, is generally made of ABS (acrylonitrile butadine styrene) or PVC hard plastic. The pipe sections come in 8-foot lengths with a diameter range of 1 1/2 to 4 inches to serve different types of water fixtures. The pipes join together with primer, cement and plastic fittings (couplings) which are available in different angles. If a fitting has broken, it needs to be cut out of the sewer line and a new one cemented into place.

Mark the PVC sewer pipe 6 inches on each side of the broken fitting. Make a straight cut through the pipe at both marks using a handsaw or circular saw. Remove the broken fitting and scrape off any burrs from the cut pipe ends with a utility knife.

Cut two sections of PVC pipe longer than 6 inches. Remove burrs. Brush PVC primer to the inside ends of a new replacement PVC fitting (it will be the same size and shape as the old broken fitting), as well as one outside end of both newly-cut PVC pipe sections. Then prime the outside of the existing cut pipe ends, and also the insides of two straight PVC couplings.

Brush PVC cement onto the primed end of both newly-cut pipe sections, as well as the inside ends of the new replacement fitting. Push the pipes into the ends of the replacement fitting, and hold them in place for five seconds while the cement dries.

Hold the new fitting and attached pipes in place against the existing cut pipe ends, and mark each new pipe where it will attach to the existing pipes. Saw through each of the new pipes at the marks, remove burrs and apply primer around the outside ends of the pipes.

Brush cement around the outside ends of the existing pipes, the remaining outside ends of the pipes attached to the new fitting, and the insides of the two straight couplings.

Push the couplings onto the ends of the existing pipes, and then push the pipes attached to the new fitting into the other end of the couplings. Hold in place for five seconds.

Tip

If using ABS sewer pipe and fittings, use ABS cement. No primer is needed.

Warning

Be careful when making attachments. The cement bonds quickly and the only way to fix a mistake is to cut the pipe again.
