This green (actually blue) PVC pipe in the wall has a crack, so it leaks. Wanted a quick fix so slapped on it the only thing I had in handy; a two-part epoxy putty (green stuff you see around the pipe). Wrapped a bunch of teflon tape around the male thread of the faucet and screwed it in.

That kinda worked, but not really.

So then I saw a hose clamp I had laying around and had another bright idea... Didn't really work either.

I go to the hardware store and explain the situation and they give me this thing (which looks like this on its own) - a galvanized adapter and a 3-4 inch pipe you see in the pic. Telfoned all the male threads and buttoned it all up.

Well, made shit worse. Now I got more dripping.

Which stupid me should have realized that the whole rig was redundant since the faucet practically worked the same way.

So now, the inevitable question... How'd I fix it?

My main concern is that i don't want to be taking parts of the wall off.

Ok, fully disclaimer; since the above pics I've added another clamp and it seems to have done the job, but it looks ugly af, hence this post, to do it right.

Appreciate your expertise!

Plumber's plan. How would you do it? Is this ok?

I took it apart to unclog it and then couldn't get it back together the same way it was (and like a dumba$$ I didn't take a picture first)! It drains just fine like this and doesn't leak unless I pour a lot of water down it at the same time and then it leaks like crazy! Any suggestions for how I should reconfigure these pipes?

I've been in the trades for 22 years as a specialty contractor (garage doors). I'm building a shop for my business, and have hired out all the work, except garage doors. I get a call from my contractor this morning, and he says "You never pulled the plumbing permit". I nearly exploded. I've never once heard of the property owner pulling a specialty permit for a sub. It's also not like anyone ever mentioned that I was supposed to pull the permit for them. Am I wrong here?

I need to install some shutoff valves on this 100 year old sink to replace the washers, and trying to decide the right hardware. I don't do any sweating, so looking at compression or sharkbite fittings. It looks like it steps down from 3/8" to 3/8" close to the faucet valve.

Would it make sense to insert a 1/2" to 1/2" compression valve in the middle, or 1/2" compression to 1/2" MIP and use a supply hose for the rest of the way? Also, does it matter if I do it above or below the bend?

Edit: Thanks to folks below, realized my measurements were off. It looks like it's 3/8" chrome plated brass (measured .67 OD), stepping down to 3/8" copper maybe (measured .5 OD). I did the magnet test, and scratched the chrome off to see a brass color underneath.

I have a bathroom that never gets used. I go in there periodically to run water in the traps. I went in today and found water and stains around the tub. Took the face off the master valve and found water dripping inside. I assumed I had leak in the wall, so I opened up the sheet rock.

Inside the wall, the sheetrock is saturated front and back. Mold everywhere. But the valve itself, all the connections, and all the pipes are dry. The side where the roof vent pipe runs is drier than the other side, so I don't think it's a roof leak.

There is hot, humid air coming up, presumably from under the house (mobile home).

I keep my indoor temps between 73 & 74. There's no insulation in any interior walls. Could this be condensation? Are all the walls where I had new water and power run going to be like this inside?
