you can repair by welding. using the right electrode you can fix the hole.
There are putty's available that can patch it like a band aid, but it will not last.
If it's a green corroded pipe then it's old copper. -You can't fix it. Replace all the length of corroded pipe with PEX and a union at each end
There are many ways to fix a burst pipe, if you are experienced in soldering you could re round the pipe closing the burst portion and solder the cracked section, or simply cut the burst section out and solder in a new piece withe two couplings. For the less experienced I would recommend cutting the pipe and using a shark bite repair fitting, it comes with detailed instructions and is made just for the situation you described
This depends on the size of the copper pipe and what class it is. For example, copper pipe half inch class 0 and copper pipe class 3 have a wide weight difference because the wall of the class 3 copper pipe is much thicker.
if it is a slow drip or sepage, it will make, @ particles in the water will fix it, if it is a steady drip then you will have to take it apart and wrap the pipe fitting with teflon tape, or use a pipe sealer on the threads,
A copper pipe is a conductor :) x
Use a pipe cutter to cut the connector about two inches away on all sides. Use a shark pipe connector to replace the copper T-connection with aCPVC connection.
In some applications, copper pipe can be TIG or MIG welded to copper pipe or to fittings. One example might be in antenna construction, but this is not what we usually encounter. Normally we braze or solder copper pipe to other copper pipe. We can also use a number of mechanical connections like compression fittings. Flare fittings are an example of this.
It would depend on where and why it cracked.
$34.89 installed per foot is the value of copper pipe.
