ABS pipe is the black pipe that is required use for sewage and drain pipes. It is restricted for usage. The fittings on these pipes are put in place using solvent glue and plastic fittings. ABS is a great pipe that will take all the household chemicals that drain through it for many years. It does become brittle over time and repairs may be needed.
Step 1 - Remove the Old ABS
When this pipe becomes brittle it may leak. As the fittings are put together using solvent glue they are not that easily removed. The easiest thing is to cut out the old piece of pipe including the fittings. Turn off all water supply going into the pipes. Using a straightedge and a pen draw a straight line across the pipe to cut. Using your hacksaw, cut the pipe at both ends. Carefully remove the section.
Step 2 - Prepare the Fittings
Using the cleaner, then the primer that comes with the pipe solvent, clean the ends of the pipe you are going to add the new fittings to. Measure the length of pipe you need to replace the piece you just removed. Using a deburring tool, (not sandpaper) remove any plastic shavings making the pipe smooth. Then clean it using the steps you just did above.
Step 3 - Install the Fittings
Using the swab in the bottle of solvent, apply to the outside of the pipe and the inside of the connector. Slide the connector over the end of the new pipe and turn 1/4 turn to set and then hold until cement dries.
Repeat to the other end. Now apply the cement to the ends of the fittings on the pipe. Push them over the pipe and turn 1/4 turn and hold until cement is dry. About 30 seconds you can let go. If there is any excess cement wipe it with the rags. Be sure to get any off your skin if any makes contact.
Step 4 - Finish Up
Now that you have installed the new fittings, turn the water back on and test for any leaks. There should be none. Make sure you tightly fit the lids back on all your sealants and cleaners. They will last for quite a time and you can use them on future repairs or projects if they are tightly lidded.
