How to Install Plastic Sewer Line Joints

Sewer line joints are easy to work with, requiring only some rechecking of calculations and measurements before commencing forward with the job. Finding out the size of sewer piping required is usually a matter of calling the local permit office as well as referring to possible plumbing codes. Once that's done, the hardest part is mostly getting into tight spaces to carry out the work, but saving on large plumbing bills can be quite an incentive.

Things You'll Need

• Tube cutter, hacksaw or power saw
• Plastic pipe and fittings
• Utility knife
• Emery cloth
• Primer
• Solvent glue
• Rag

Instructions

1. Measure the desired length of pipe and cut using either a tube cutter, hacksaw or power saw. Whichever you use, make sure the cut is straight.

2. Remove the inside and outside burrs of the cut with a utility knife, making it smooth. Emery cloth can be used for larger burrs, but leave the outside of the pipe as smooth as possible.

3. Test the desired joint like a coupling or 90-degree "elbow" joint to make sure the pipe fits tightly inside, and all the way in.

4. Apply the plastic primer (skip this section if the pipe and fitting is black) to the pipe end, as well as the inside rim of the fitting. This helps the glue get a better hold.

5. Apply solvent glue to the outside of the pipe end as well as the inside of the fitting. Quickly place the tube in the fitting by pushing it in and turning it to the desired position. Hold the pipe for a good 20 seconds to help the glue harden. Wipe away excess glue.

Tips & Warnings

• Always measure the pipe length at least twice before cutting. Check and recheck the desired position of the fitting on the pipe before gluing the fitting to the pipe. Take extra care in cutting the pipe so a straight cut is achieved. ABS (black) pipe requires no primer but is restricted in some areas. PVC (white) pipe is superior to ABS, but needs a primer before gluing.
