How to Repair an ABS Pipe

What You'll Need
Pipe Cutter
ABS Primer and Glue
Measuring Tape
ABS Pipe
ABS coupling

An ABS pipe can develop cracks in its surface due to increased stress, inappropriate temperature or just due to usage over a period of time. These cracks usually appear at the bends or the joints and can be detected by spotting leakages. Pipes carrying water will start dripping and harm their surroundings with the moisture, so it is imperative that quick and effective repair is made to avoid a bigger damage.

Step 1: Analyze the Crack and Take Measurements

Carefully analyze the severity of the crack. If it is a small crack, then you can use ABS cement or plastic tape to cover it. However, for a long lasting solution and more serious cracks, replace the damaged portion of the pipe. Use measuring tape to measure the length of the crack and get an ABS pipe measuring at least 3 inches more than the measurement.

Step 2: Turn off Water Supply

Turn off the supply of water to the pipe. If the individual supply to the pipe cannot be detected, turn off the main water supply for the duration of your work.

Step 3: Cut the Damaged Portion of the Pipe

To avoid a mess, place a bucket beneath the damaged pipe to allow it to catch the drippings. Use a pipe cutter or a hacksaw to cut the pipe from the boundaries of the crack. Use a dry piece of cloth to clean the inside and the outside of the two ends of the pipe that are exposed after cutting.

 Step 4: Attach Couplings

Use the primer bush, which is part of the cap of the primer can, to apply purple primer on the inside of the coupling and on the outside of the pipe. Make sure that primer is evenly applied and that there is no dirt on the applied area. When the primer is still wet, apply glue on the outside of the pipe and inside the coupling. Now, slide the coupling onto the pipe and give it a 90 degree twist to allow glue to spread evenly. Repeat similar procedure to attach a coupling to the other pipe as well.

Step 5: Fit the Pipe

Measure the gap left between the two ends after the couplings are attached. Compare your measurements with the piece of pipe you intend to fit as replacement and make appropriate adjustments using a hacksaw. With the couplings attached, fit the pipe in the couplings to link the two ends of the cut pipe. Use similar procedures of applying the primer and the glue with the brush to make the bond. Allow the glue to harden to solidify the bond.

Step 6: Turn on the Water Supply and Check for Leaks

After allowing considerable time for the glue to settle, open the water valve and let the water run through the pipes. Check for leaks and drippings while the water runs through the pipe. Once satisfaction is guaranteed, empty the bucket that was placed beneath the pipe into a drain.
