How To Flush Copper Pipes After Soldering

Copper pipes can be soldered using a propane torch and lead-free solder. After the solder has been applied and the joint has cooled, the copper pipe must be flushed to remove any remaining flux and debris. This can be done by pouring hot water over the joint until it runs clear.

How To Flush Copper Pipes After Soldering

Copper pipes can be flushed easily after they are soldered. The solder joint can act as a plug and hold back the flow of water long enough for the flux residue to clear. First, close the valve on the pipe that you just soldered. Second, open up the faucet on the nearest sink and let it run until the water is clear. Finally, close the faucet and reopen the valve on the pipe.

How Do You Clean Copper Pipes After Soldering?

There are a few ways to clean copper pipes after soldering. One way is to use a vinegar and salt bath. Another way is to use a flux brush.


Wrap-Up

After soldering copper pipes, it is important to flush them with water to remove any flux residue. This can be done by attaching a hose to the fitting and running water through the pipe until it runs clear.
