Someone refresh my memory.
Drain pipes with different material.(sched 40),PVC,etc.
The only thing I can see Bob would be the glue used.
Weld.On 794 which is green is recommended for gluing ABS and PVC.
Other than that would be older versions of the ABS.
What is ABS pipe?
ABS pipe is black rigid, non-pressurized plastic pipe used to drain your sinks, tubs, showers, toilet and washing machines. It is also used to vent the drain and waste pipes.
What is qualifying ABS pipe?
Qualifying ABS Pipe is pipe that:
- has creaked circumferentially adjacent to a joint or “fitting”;
- has leaked; and
- was manufactured by one of the five defendant ABS pipe manufacturers during the relevant time frame.
There are five manufacturers of ABS pipe that for discrete periods of time between 1984 and 1990 that produced ABS pipe that allegedly may crack circumferentially at the joint. Those manufacturers and time periods are:
Centaur: January 1985 through September 1985
Phoenix: November 1985 through September 1986
Gable: Periodically between November 1984 and December 1990
Polaris: Periodically between January 1984 and December 1990
Apache: Periodically between November 1984 and December 1990
ABS pipe is marked on the outside wall of the pipe. The markings include the name of the manufacturer, references to code specifications and a date code. The date code, when translated, reveals the date the pipe was manufactured. Here are examples of how the pipe is marked:
To help you ascertain if you have the defective ABS pipe, please review the attached diagram:
Notice that the crack is adjacent to the joint and runs circumferentially around the pipe.
How to locate and examine ABS pipe:
- Attic inspection: The most accessible point to examine ABS pipe is usually the attic, where it serves as vents for kitchens, bathrooms and/or other sinks. The pipe can be horizontal or vertical. The vertical sections usually exit through the roof.
- Under sinks: The section of pipe coming out of the wall and connecting to the sink trap may be ABS. If the pipe is threaded or looks molded, then it is not ABS pipe.
- Crawl space: If your house has a raised foundation (has a crawl space under it), then pipe may be identified by looking underneath the house. This will usually give access to large amounts of pipe.
- Cleanout: If your residence has exterior cleanout, the name can sometimes be located at this point.
These are the easiest locations to inspect. Write down all markings on the pipe. This information must be included with you Registration Claim Form. ABS pipe comes in different diameters and is joined together by a variety of fittings. (See diagram below.) The configuration of the fittings, which come in all different shapes and sizes, is not relevant. ABS pipe is always black.
More tips for identifying qualifying ABS pipe:
Determine when your house was built.
ABS pipe is black rigid, non-pressurized plastic pipe. If your pipe is flexible or made of metal, such as copper, iron or galvanized steel, or carries pressurized water, it is not ABS pipe.
Qualifying ABS pipe was first manufactured in 1984. If your plumbing is older than 1984, it cannot have the qualifying ABS pipe.
Remember: Not all pipe manufactured by the defendant manufacturers during the period will crack and result in leaks. You may have pipe manufactured by one or more of the defendants that will not leak. If qualifying pipe has already been repaired or replaced, you may seek reimbursement (with adequate proof of repair) unless you have already been reimbursed or had already received a free repair or replacement. :)
Ok that’s what I thought.
Need a certain kind of adhesive.
Another great answer (Thanks Buddy)
Can I call it a dielectric for plastic :):)
Do a search. Here’s one relavent thread: http://www.nachi.org/forum/f22/abs-cemented-pvc-36842/
Sounds like I should just caution that connection is not recommend but may be ok.
