How far should I go with this.
Now that I've got the interior of the 74 taken apart I'm wondering if I should go ahead and replace all the ABS pipe and fittings. It's not like I don't have plenty of other things to do, or that I see anything wrong with what is in there now. Some people have told me they have had trouble with old ABS glue fittings leaking in their house plumbing. I already plan on changing out the copper to Pex.
In general have any of you folks had problems with 30 or 40 year old ABS?
