I'll be replacing my sink and counter this weekend, and I need to replace the water supply shutoff valves under the sink since they don't shut off lol.  On one side there is a tee and then a valve for the dishwasher, and then the broken valve for the sink.  All the connections are soldered, with about 1/2" between the tee and the valve I need to de-solder/replace. 

This will be my first time soldering copper pipe, do you guys think I need to worry about disturbing the other joints when I de-solder the old valve and then solder in the new one?  I'd rather just do the one joint than remove it all and re-do it since none of the connections leak.

Heat transfers pretty quickly out of the immediate work area when dealing with copper, you'd have to put a LOT of heat into any one joint to get multiple ones coming loose.

Also, it's bes to solder with your head directly under the joint, no safety glasses, and remember to apply the torch to the solder and not to the pipe itself.  PROFIT

i dont think you ever desolder pipes, you just cut them off and put new stuff on.

also with the vlaves, make sure that they can take the heat of soldering. some have rubber gaskets and stuff that need to be taken out before soldering.

Shut up.  I'm trying to get Jay to hotrex himself in the eye, stop giving him good advice.

Unless there is another solder joint like an inch away, you shouldn't have to worry about anything else coming loose. I'd much rather just cut it off like previously posted and solder a new one on though. Make sure you use emery cloth and rough up the surface that's going to be soldered.

done this before just heat the joint up u'll notice the solder  start to run down the pipe or bubble , start twisting the pipe u want to remove ... not hard to do ....make sure its with bare hands (gloves wont grip it right), clean (with acid) and ream all joints before re soldering to prevent leaks ....


or just cut the fucker and go from there your choice

[ghettoturbo]

thanks a lot guys...so far i have burned hands, and molten solder stuck to my beard



Just kidding, its all done just waiting for it to cool so I can shut the valves and test it.  I decided to man up and just replace it all.  I couldnt cut the old stuff off since it seems someone did that when they ran the line for the dishwasher and didnt leave me much to work with so I had to desolder.

I'll give an update later.  Lowes came to drop off the countertop and half was fubar, so the job might be left incomplete for a bit.

Update: its all done and not leaking, but with a few casualties.  FYI I apparently suck at working with 1/4 turn valves.  I got one to installed with no problem, and then proceeded to apparently destroy the seals in a few others no matter how hard I tried to just barely heat them.  No matter what, it would drip a little past the seal.  So I had the wife pick up a few multi-turn valves so I could disassemble them before soldering and blammmo...all finished with no apparent leaks.

AND PICS OF THE WIFE NOW  :yes:

[ghettoturbo]

None of her, but here are a few quick ones the wife snapped after we had just started and just as we were wrapping it up:

Glad to see plumbing in your house involves massive liquor purchases.
