just get a kick out of calling someone a "troll', just because it be in th eir eyes against the norm...Not everything is perfect in this world. Perhap s I am to be blamed for the wording of my OP..so I will try to straighten i t out here the best I can. I did call this guy a plumber mainly cause he do es plumbing work for a company that just does drain cleaning.
That's right, a drain cleaner isn't a plumber. Saying someone is plumber implies that they have skills way beyond cleaning out a drain a line. If you said a drain cleaner told you to call someone else to fix it, that would make sense.
If the 'troll' caller actually read my OP thoroughly, he would of read that he made me sign a paper wavering any liability in breaking a pipe, his com pany does not do that.
I read where you said he had you sign a waiver of liability. No way from that for us to figure out that this "plumber" is actually a drain cleaner, who works for a drain cleaning company that doesn't do more than clean drains. A full service plumbing company might also have you sign a waiver..... "Customer acknowledges that we need to remove plugs, open access points, etc and with any plumbing system, especially old ones, there is a risk of parts failing. If that happens, it is not our responsibility" , etc.
Right now, so I could use the sink, its working just fine, so picture takin g would not show anything, mainly cause the threaded pipe area that he scre wed in was covered with 'plumber's tape', which I had from previous problem s.
Plumbers tape or dope is routinely used on threaded fittings, including brand new ones. Has nothing to do with seeing what the plumbing in question looks like. And picture taking would show a lot, in particular th is mysterious 3" nipple.
He gave me the measurements. I wanted this info here so I could be prepar ed the next time if and when it would clog, I will have it available to hav e the 'plumber' or 'handy guy' insert it. Guys like you make it a pleasur e in this forum not to rush to judgement.
You could do that. But I would be careful about getting some "handy guy" to screw around with the described 3" pipe. There may be better, safer, easier solutions to the problem. For example, if that nipple really exists and is screwed into a T inside the wall, and some "handy man" type tries to take it out, because you hand him a piece of pipe and tell him to put it in, you could wind up with more expensive and bigger problems. Someone with experience might figure out a better, easier solution that doesn't even require the 3" nipple. They also might tell you that other stuff under there needs to be replaced too, and it changes things so the parts required are different, don't require that 3" nipple, etc.
If you really want to go buy it, based on the limited info you've given, what you want is a 3" long, 3" galvanized nipple. Which brings us to the next problem. Very short nipples are called "close nipples". I just did a quick search and it appears that a 3" close nipple is 2 5/8" long. The next size up is likely going to be a lot longer than 3". If this pipe really is 3" diameter, it's highly likely what's there is just a 3" close nipple. That's why it's probably not a good idea to be going buying stuff based on a drain cleaner's recommendations and to let whoever is going to fix it determine what it needs, the best solution, etc.
