Can you solder a pipe with water in it?
Don’t try to solder pipes with water in them. 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.
Why is my solder not sticking to the pipe?
Most likely you don’t have the base metal hot enough for the solder to wet it. Make sure the pipe is empty, and try waiting a bit longer before applying the solder. The base metal should be hot enough to melt the solder directly. , former Worked in IT, Dish Washing, Sailmaking Etc.
Does solder corrode in water?
In the case of solder joints, ions may be present in the flux residues that remain after the soldering operation has been completed. In the presence of water, including water vapor in high humidity conditions, these ions will once again become active and can pose a corrosion concern to the solderjoint.
Does plumbing solder go bad?
No, it can’t go bad. A properly done solder joint will last the lifetime of the piping. Sometimes you get a cold solder joint in which the two pieces of the joint do not bond(usually caused by bad preparation) but it seems to seal for a while then starts leaking.
Does flux help solder stick?
Flux helps solder flow or “wet” properly in terms of its adhesive property while molten and helps prevent oxidation. Flux is necessary for the “reflow” of solder. The word flux itself regards flow or reflow. Solder wire, usually can have a rosin paste core, or is simply, rosin flux.
What type of solder is used for plumbing?
Acid core solders are most often used in plumbing applications to join metal pipes or sheet metal. Rosin core solder is also fabricated with a hollow core inside the solder wire, but the flux used is a milder variety made of rosin, which is a solid form of resin derived from conifers such as pine.
How do you get water out of a vertical copper pipe?
Simply insert the flexible tube from the spray nozzle into the copper pipe that you wish to drain. Have a small basin or container nearby to catch the water, and then simply squeeze to draw the water out of the pipe, through the spray nozzle and into the wastewater container.
Can solder flux go off?
Flux is one of the three things you need to make a solder joint. You need heat, metal and flux. Don’t take any chances. If it is expired, don’t use it.
