Problem with bad solder job...help!


I finished up my basement project but since it was still cold I didn't complete the run to the outside hose. When I completed and turned on the water I heard a hiss in the laundry room. The culprit was the shut off valve. Now I have a problem...this area is drywalled so I am limited on room. I had an access panel which I've already cut bigger. How can I repair this without cutting pipes???

The valve at the bottom left is leaking. It's the left side.

Is it the sloder joints or the packing nut? Packing nut can be snugged up and that will usually resolve the issue, if the joints sorry ya gotta cut the pipe, and resolder. SOMETIMES you can clean the outside on the joint, flux the heck outta it and reheat the joint and it will flow,add solder to insure a full joint. Then use a slip coupling to solder the cut back together

Gonna have to cut that pipe off and redo it. Trying to get it to take a soldered repair is risky at best, because even if it holds, you aren't getting much penetration of the solder into the leaky joint....So, it'll probably leak again in weeks, months, or years.

You might have not got a good joint due to a small amount of water in the line. If that is the case, take some white bread and make it into a doughball. Jam the doughball up into the pipe a few inches away from where you're soldering. It will stop the water from migrating to the heat and will dissolve immediately once the water is turned on. Works great. Much cheaper than the commercially made pipe plugs they sell in the box stores, and works every bit as well.

Ok, I know that I need to cut the pipe and redo. Here is my problem...the pipe is tight to the cinderblock wall. I am not sure I will have room to sand the pipe then solder properly. Any tips or tricks I can use?

Cutting it would be the only challenge. Might have to use a fine hacksaw blade, being careful not to deform the pipe.

To sand/clean it, use strips of flexible emery cloth that are available at most hardware stores' plumbing section. They'll easily slip between the pipe and the wall, and you just pull back and forth. Use a wire brush on the inside of the fitting.

Just brush your flux liberally on every mating surface and heat the fitting with the torch. You don't have to get around the back side with the solder...The flux does that. All you have to do is touch the solder to the hot joint in one place.

Where a lot of people screw up is they continue heating the joint after it has been soldered, in an effort to put more solder around the edges. A friend of mine once thought it was more like welding! The flux will suck the solder all the way around the joint, so you don't need access to the back side.

OK Gone here da deal: Get the emery cloth for plumbing which is a roll of it and 1 1/4 wide. YOU CAN pull that right between the wall and the pipe and loop it just pull like a bowstring :}:}. Pull the emerry THRU the coupling also!!!!!! YES clean the inside of the fittings. MAKE VERY SURE YOU USE A SLIP COUPLING Normal coupling will NOT work. FLUX<FLUX<FLUX A joint cannot be too clean. Heat center of coupling. Once you have it fluxed and together you can put spacers between the block and the pipe AWAY from the joint area so the flame will wrap around the joint to avoid a "cold" section.
NOW GIT ER DONE AND BACK OUT ON THAT DAMN BASS BOAT You are creating massive problems of overcrowding in the lake!!!!!!!!!!!! Clean it out!!

PS pull the pipe away from wall when you flux and get it on the back side fer sure

How bout you...

1. Turn off water at main house valve.

2. Turn on water at kitchen and bath.

3 Open outside faucet.

4 Use wet dry vac to suck all the water out of the line.

5. Re-solder

You may have to heat your joint a bit longer to dry the area out.

May not work, but may be worth a shot.

Well...I cut more dry wall away...cut the pipe in the garage and cut to the right of the valve. This allowed me more room to solder. I resoldered left to right then the garage. All is water tight!!! Funniest part was when i turned the water back on the bread I used to plug the water came out of the garden hose like a turd squeezing out...

Skymaster...no fresh water for me...those fish are too small. All saltwater from Jersey to Maryland for me. Speaking of which...heading to Asstegue in 12 hours!

glad it all worked out
I've used the bread trick - slick
saltwater for me too - fish from Hatteras Harbor Marina
book the Release with Capt Rom Witacker if you get down there
or Capt. DM Gray on Native Son, but I think he moved to Oden's Dock last year
Sorry not plumbing....but it's a fishing thing
