Plumbing copper pipes- water keeps coming?
Hi, my husband is trying "t"ed off a got water pipe to add a washer machine (we're actually moving the current machine's location). He can't sodder the pipe back together because the water wont stop coming out of the pipe where he is trying to sodder. We've turned on all the faucets in the house over night, and he has blown air through the facucet that he thinks is the culprit. any advise?

use shark-bite push on fittings and never solder again.
that's what we now use.
plumbers trick is to use bread to clog the line just long enough to have a dry joint to sweat.

try a wet vac yo suck all the water out of the line make sure you have the main shut off and a faucet open and if you still get a little water use the bread also does husband know how to solder clean the pipe and joints use soldering paste if it is 1/2 pipe all you need is about 1/2 solder heat fitting until solder melts by touching hot fitting not by the flame of the torch

You cannot solder as long as there is water in there. Drain and open all faucets to remove any water. You could also blow air though to help.
You could try the bread trick, stuff bread in pipe to hold back the water and it will dissolve once water is back on. I don't use this method but heard it works. If I have a spot where its difficult to remove all water and seems to be always coming back I'll use a copper union, sweat in parts of union and mechanically make final connection.

That's an easy fix really... This is going to sound funny but it does work...
Take a piece of white bread and remove the soft middle part... Ball that up and stuff it in to the pipe as far as you can. That will block the water long enough to solder the connection. The bread will fall apart and come right out after you turn the water back on.
A cool trick that really works!

I have used the bread trick with success if there is not to much water. If it is in a place where you might want a cut-off, I use a valve just as gizmo suggested with the union. You can usually get a good sweat job with the valve open and then just close the valve. It should not be concealed however.

Turn off the water at the meter, then stuff the end of the pipe with white bread (old plumber's trick, bread will get soaked with the water and come out when you are done).

I assume you have turned off the water to the house..... Open the hose spigots outside. They are typically lower than the faucets inside and will drain out the rest of the water.

It does have to be shut off at the main. If there's any water in the pipe, it won't ever get hot enough to solder properly.

Turn off the water at the water main valve. Prolly by the street, under a concrete lid.
Hard to get that solder to run under water, alright.
Good Luck!
