Pipes can't stop sweating ;;

Hello everyone, I've ran into a big problem this past 2 weeks. I'm an idiot with this plumbing stuff, any help would be greatly appreciated =). My cold water pipe is made out of copper. There was a leak on the cold water pipe in the basement and we had someone came to fix it. He cut the area where the pipe was leaking and used a rubber-like material and clamp hose to connect the pipe back together.

The problem doesn't stop there, water droplets builds up around the area he fixed that causes tiny drops of water to fall, I sort of ignored it because I thought it was only condensation building up. But today when I went down the basement, it was pretty much flooded, the cold water pipe had blew. We got someone else to come in to fix it but this time the plumber used the copper pipes instead of the rubber-like material that was used to connect the pipe together.

THIS IS THE REAL PROBLEM(sorry for the caps) I am facing. The pipes are stilling sweating and producing water droplets but me and my friend can't tell what's actually making the pipe keep sweating. I am scared it'll cause another burst on my pipe and have another flood again or worst, my ceiling collapsing from the water droping ontop of it ;;.

Is there any thing I can buy that can stop the sweat build up? Any help is going to be really helpful, thanks in advance. :cry:

What area of the country are you in ? What type of heat do you have ( gas hot air , hot water heat etc ?)

Has this always happened ? Has there been any changes to your duct system / heat system/ water pipe system recently ?

Is the "condensation" just on the repair part or is it most of the line in that area. The flood would have raised the humidity in that area enough to cause condensation until the water finds its way out of that area. OR you could have a bad soder joint. Was the 2nd repair done with a torch and solder?

Who ever did the first repair was an idiot wanabe. Don't ever call them again.

The first plumber was a total idiot ~.~; they both used a torch and solder but the first guy didn't know what he was doing and used the rubber-like material which ended up bursting >.> but I realized what I still need to do, gotta get some foam insulation for the pipes ^^;

First thing I'd do is to dry the basement as much as possible. Open a door or window and use a fan to get that excess humidity out. You have to determine if the moisture on the pipes is actually condensation or if there is still a leak. I would hold off on the insulation until that determination is made. If it is a leak, the insulation wouldn't help.

Also consider that there may be perforations on that section of copper.
Could have been a bad length of pipe or I've seen leaks like that near where household chemicals or beauty shop chemicals are stored.

Get a space heater and turn it on down in the damp area, with a fan and an open window and see if it's really condensation or a leaking pipe. Don't put insulation on or you might hide that it's actually leaking and not just condensing.

You should get some reimbursement from that 1st plumber, that's plain negligence and ineptitude. Small claims court if he refuses.

That first guy wasn't a real plumber, probably an unlicensed jack-of-all-trades, master-of-none handyman. Chances of any kind of compensation is slim to none. Once again, the thing to do is get the place dried out, check the pipes carefully, especially the one that had the leak, replace any/all pipes that appear to be bad. Let it set for awhile to be sure it stays dry before insulating.

Could it be possible that there is a toilet running continuously?
