As a professional in the field of plumbing and construction, I understand the intricacies of working with various materials, including copper pipes. When it comes to soldering copper pipes, it's crucial to ensure that the surface is clean, dry, and free of any contaminants that could impede the soldering process.
Soldering is a process that involves melting a filler metal, typically an alloy of tin and lead, into the joint between two pieces of metal to create a bond. The heat source used for soldering is usually a propane torch, which can generate temperatures high enough to melt the solder but not the base metal. However, if there is water in the pipe, the process becomes significantly more challenging.
Water, being a good conductor of heat, will draw heat away from the copper pipe and into itself. As the water heats up, it will turn into steam, which is a process that requires a significant amount of energy. This energy is taken from the heat that would otherwise be used to heat the copper pipe and melt the solder. Consequently, the copper pipe may not reach the necessary temperature for the solder to flow and bond properly.
Moreover, the presence of water can also create a barrier between the copper and the solder, preventing the solder from making proper contact with the pipe. This can result in a weak joint that may not hold up under pressure and could potentially leak.
To effectively solder a copper pipe, it is essential to first stop the flow of water. This can be done by using a pipe plug or a similar device that can be inserted into the pipe to block the water flow. Once the water flow has been stopped, the next step is to dry the pipe thoroughly. This can be done using a hairdryer, heat gun, or by allowing the pipe to air dry for an extended period.
After the pipe is dry, it's important to clean the surfaces that will be joined. This typically involves using a wire brush to remove any oxidation or debris from the copper. Once the surfaces are clean, a flux can be applied to the joint area. Flux is a chemical that helps the solder flow and adhere to the metal surfaces.
With the pipe dry and clean, and with the flux applied, you can now proceed to solder the joint. The heat from the torch should be directed at the joint area, not just the pipe itself. As the solder melts and flows into the joint, it will create a strong bond between the two pieces of copper.
In conclusion, soldering a copper pipe with water in it is not advisable due to the reasons mentioned above. It is essential to stop the water flow, dry and clean the pipe, and then proceed with the soldering process to ensure a strong and leak-free joint.

Stop the water with a pipe plug. ... Soldering a joint in pipes that contain even tiny amounts of water is nearly impossible. Most of the heat from the torch goes into turning the water to steam, so the copper won't get hot enough to melt the solder. Stop the trickle of water with a pipe plug.
