ABS Drain Pipe Failure

My house was built in 1981 in New Jersey. The drain pipes are ABS. Approximately 15 years ago, I replaced a horrizontal length of 2-inch pipe that developed a longitudinal hairline crack that dripped. The pipe drained the laundry and kitchen. At the time, my assumption was that the plumber must have used a defective length of pipe. I just discovered a short vertical length of 1 1/2-inch pipe from the kitchen sink that has a hairline crack and drips.

A similar ABS failure was described in this forum two years ago. [Search for "ABS failure" and see the post entitled, "drain pipe failure - pics"

There was a class action lawsuit in California over defective ABS pipe. Those failures were circumferential, guillotine-type breaks. Different than the foregoing failures.

Any thoughts on what is going on?

Have other readers of this forum experienced longitudinal failures of ABS pipe?

Other than cutting out the defective section, any thoughts on fixing hairline cracks that might run the length of the pipe?

No other way to repair ABS or PVC pipe than replacing it. You will need to use a no hub connector.

I have seen a lot of ABS failures similar to your description. IMHO ABS = The cheap fast method. I consider Schedule 40 PVC to be higher quality.

The reason for the failures is not generic to ABS pipe in general. It derives from unscrupulous manufacturing practices. The offending parties used partially recycled resin in their products. Unfortunately, only virgin resin will do. Sadly, these bad guys hit the road when the wheels started to fall off. I'm sure this scenario will be repeated over and over with various products coming from our good friends the Peoples Republic of China.
