How do solder copper pipes with water in them?

That cant be done because as long as there is water in them the temperature of the pipe wont go up enough to allow the solder to flow. you have to remove the water.


How do you get water out of a pipe in order to solder copper pipes?

First off, you should shut off the water source. Then you must drain the pipe. After that you can clean up the area to be soldered, apply some flux. Now you are ready to solder. The pipe doesn't need to be bone dry, since it will dry as you solder from the heat.


Should you solder or braise brass water fittings?

Always and only solder.


Why is lead-free solder used?

Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.


Can wet copper pipe be soldiered?

Wet on the surface is no problem, it will evaporate with the torch. If there is water in the pipe, it will not solder because the water keeps the copper from getting hot enough. As long as the water is below the point of solder, it will work. Open the nearest valve or have some way for the steam to get out of the pipe.


What epoxy stick is best for water drips on copper pipes?

It is called Brazing rods or lead free solder


What is sweated copper?

Sweating copper is a method of joining two pieces of copper, generally copper pipes. The surfaces to be joined are first cleaned, then heated generally with a gas torch, then a flux is applied (flux is a material to prevent oxidation of the copper when heated) then a film of solder is run onto the cleaned surfaces whilst hot. This solder is "wiped" off leaving a fine film of solder on the copper. This is generally referred to as priming. The two surfaces can now be soldered together to make a water tight joint. Sometime bronze is used instead of solder but the operation is similar.


Can you solder a brass fitting to copper?

Certainly look up Flagg Flow T.P Fittings T.P thread-less copper fittings will FIT on schedule 40/80 /120 Brass pipe Ideally it should be brazed but soldering will hold domestic water pressures Also many solder fittings ARE CAST BRASS rather then wrought copper

How reliable is silver solder to spot solder a 5 mil hole in a cold water copper pipe when this method is the only option?

As long as you clean the pipe well and it doesn't have any moisture in it when you solder it, it should be alright to form a patch over the hole with solder. Some is going to go into the hole and form a plug so it should stay. Another option is to clean that section of pipe and split a coupling so that you have 1/3 to1/2 of the diameter. Clean that well and solder the piece over the whole. This will make a much stronger patch.


What solder do you use on copper tubing for plumbing?

Copper tubing solder "Solder" is an erroneous term as solder mean lead which of course is banned (safe water drinking act) Sweating is another term for "soldering" Copper can be joined by various alloys such as 95 % tin -5% Anatomy or one of the many silver bearing types of low temperature alloys. For the strongest possible joints brazing is the best way to go with a tensile strength over 87,000 PSI compared to soft solder joints of 16,000 PSI For DWV copper joints one can use one of the lead tin solders such as 50 -50 as it is quite easy to work woth.
