 Centaur ABS pipe date code
Author: Tomasco (CA)

Just found this pipe has failed adjacent to a coupling. Need to find the formula for translating the date code from the letters and numbers on the pipe. Pipe located in wall, and need to decide if repiping is needed .

The suit is over:
In terms of ID on your pipe to see if you need to replace it on your dime, all the links on the website are inactive and refer to this phone number for questions:

ABS pipe is rigid black plastic pipe used to drain sinks, tubs, showers, toilets, washing machines and dishwashers. Six class action complaints have been coordinated before the Honorable Mark B. Simons, Contra Costa County Superior Court, State of California, and allege that ABS pipe manufactured at certain times between 1984 and 1990 by Polaris Pipe Co. ("Polaris"winking smiley, Gable Plastics, Inc. ("Gable"winking smiley, Centaur Mfg., Inc. ("Centaur"winking smiley, Centaur Marketing, Inc. a/k/a Phoenix Extrusion Co. ("Phoenix"winking smiley, and Apache Plastics, Inc. ("Apache"winking smiley is defective and may leak. The overwhelming majority of the allegedly defective ABS pipe at issue is located in the State of California. All defendants in this action deny all liability and deny that the ABS pipe at issue is defective. The Court has not yet ruled, one way or the other, on the correctness of plaintiffs' claims. In addition, the fact that your residence or building has ABS pipe manufactured by one or more of the defendant manufacturers does not mean that your residence or building has the allegedly defective ABS pipe at issue.

Another website gives the dates that the offending pipe was manufactured:
Centaur: January 1985 through September 1985

Since pipe is a fast moving commodity, this gives you a fairly tight time frame for when your house would have been built to be using the bad pipe.
