How do you fix a leaking union joint?
The union joint itself consists of two female threaded end nuts, with a central threaded holding nut which when tightened in place holds the end nuts together. Repairing a leaking union requires removing the union and applying more sealing tape to the threads before refitting the joint back into the pipeline.
How to sweat copper pipe to prevent leaks?
How to Sweat Copper Pipe – Soldering Your Copper Pipe 1 Test your fitting to verify proper soldering temperature. 2 Begin to solder. 3 Reheat complex joints. 4 Clean the soldered joint. 5 Check for leaks in your pipe.
What happens if you re solder copper pipe after water leaks?
Solder at the interface of the things you are joining and if done right, the solder will wick up into the cavity very clearly. If it balls off, you are either tool cold, not fluxed, or the pipe wasn’t cleaned. Repeat until you get it right After several of these episodes, you’ll get better. Life is long and plumbing unreliable.
What to do if your copper pipe is too hot?
If the joint forms a t-junction, begin at the base, move up to the top, and then down the other side. If the joint is vertical, move the solder around the joint, covering it evenly. If the copper is blackened or the solder beads, appears discolored, or drips out, your pipe may be too hot.
How can I fix a leaking water pipe?
Drain the water, then solder Apply soldering flux around the whole joint and apply heat with a torch until the old solder melts. Add new solder until a shiny ring of solder shows all around the joint. Let the pipe cool for five minutes, then turn the water back on and cross your fingers that you stopped the leak.

Why do I have to re-solder my copper pipe?
If the copper pipe you are dealing with is old enough the pipe may be eroded enough to be too thin to solder well. If you are getting pinhole leaks that spray water perpendicular to the pipe this might be the problem. If you are getting sprays of water parallel with the pipe right at the fitting than you have to re-solder.
How often does a pinhole leak in copper pipe occur?
Under the right (worst) conditions, copper pipe may develop pinhole leaks within only two years of installation. Pinhole leak in copper pipe is a common problem all over the US.
