First off...I don't know much about plumbing. My wife wanted the shower/tub fixtures in our guest bathroom replaced and it didn't look too hard to me. I removed the screw on tub faucet piece and when I screwed the new one on, there was about 3/4" gap between the spout and the finished wall (tile). This was the moment I learned not all tub spouts are a standard length. So the copper nipple at the end of the pipe looked like it was attached atsome point to extend the pipe assembly and might unscrew from the copper pipe (told you I don't know much about plumbing). So I grabbed a wrench and tried to unscrew it and you guessed it...the whole pipe turned and I heard the little crack sound inside the wall. I had only turned it 1/16 of a rotation or so and I turned it right back to the original position. It didn't snap off and it seemed to screw right back in. I suspected I shouldn't have done that so I jumped online to read about it. What I have found is that it might have been soldered and I may have broken that seal now requiring a bigger project of getting into the wall and repairing it, or it might be copper pipe screwed into galvanized pipe? Am I way off on this? At this point, am I going to hurt anything by unscrewing it and taking it all the way out to see what the status is? If it's screwed into galvanized pipe, can I just go buy a shorter copper piece, screw it into the galvanized pipe, put my tub spout on and be done with it? I appreciate your advice in advance.

I read over the sticky notes. Gave me a lot of ideas, but don't see this issue exactly. I have a toilet with personality. I flush the toilet after using and works fine. I can use it and flush and it is stopped up, and water backs up in the toilet coming up to the rim of toilet seat and I plunge it to get it to go down, and then sometimes I flush it with nothing in it at all and it stops up and water comes up to almost to the rim near toilet seat, and I plunge and it goes down. I have bought a rotating snake from a bulding supply company to try to see if there was some type of partial block and it did not help. I have another toilet in my house that works fine all the time. I can actually feel the power of suction when I flush it. Both are the same age, and same toilet make and model. So for some reason I am not getting this power in the one toilet that acts up. I have no back up anywhere in tub, sink, or anything. To me it seems like a suction problem pulling the water down the drain. I have replaced all the insides in the tank. Still the same - I don't know enough about how toilets work to know where the pull down the drain is coming from - seems like I may have build up in this toilet. I read about cleaning a blow hole of hard water build-up, but I do not know what the blow hole means or where it is located. So are there areas in the toilet that I can clean and make sure are not clogged with build-up? Would that affect the power of the flush? Please give me some guidance - it is frustrating to say the least - and it is the guest bathroom - so I have to keep a plunger out by the toilet in case it happens to them -
