Until one or more licensed Plumbers contribute, I'll give it a shot. I suspect that local Plumbing codes will specify which is accecptable. So, temporarily, my opinion follows. Over the last 50 years, I have lived in three houses, all of which were/are 50 years or older. They all had 3/4 inch rigid copper water supply pipe systems, and all jionts were made with solder, including the underground service entrance lines. In my 64 years, I can recall only 5 leak failures, none of which were related to the soldered joints. Two leak failures in one house were due to the use of galvanized steel yard hydrant risers from the underground copper. The leaks occured at the bare steel where the galvanize was removed in cutting threads on the riser pipes, and in addition, the soil in that area was extremely acidic, and highly corrosive, resulting in "electrolysis" eating holes through at the threaded joint between the copper and galvanized steel. The second house developed leaks, three times, in the underground service entrance line, and analysis indicated that they were far from and not related to the soldered joints. Microscopic analysis of the holes, revealed that the holes developed from flaws in the pipe wall related to microscopic iron which got into the pipe wall during manufacture. It is interesting that it took 54 years for the flaws to corrode away, resulting in leaks. So, unless there is a code prohibition of solder joints in copper pipe for underground use, I suggest that soldering is fine, and braising would be an expensive overkill.j3h.

How to repair cut underground copper tubing from propane tank?
To repair cut underground copper tubing from a propane tank, you will likely need to excavate the area to access the damaged section. Once exposed, you can use a compression fitting or flare fitting to reconnect the tubing. Make sure to follow all safety guidelines when working with propane. It is recommended to consult with a professional technician for safe repair and to ensure compliance with regulations.
What is a common metal used in wires to conduct electricity?
copper or even more often brass Copper and aluminum are used in house wiring. Aluminum is typically used in the entrance cable and copper for everything past the breaker panel. Aluminum was used for house wiring a few decades ago but it was linked to numerous electrical fires because the connections would weaken over time.
Can you use soldered copper joints under ground?
No.
What type of copper is typically run underground?
Type L or Type K copper pipe is typically used for underground applications. These types of copper pipe have thicker walls than Type M copper pipe, making them more suitable for underground installation where they may be exposed to greater pressure or potential damage. Additionally, this thicker wall helps to prevent corrosion and allows for increased durability underground.
Is the pipe soldered?
Copper pipe is soldered. Steel pipe is welded. Plastic pipe (pvc) is glued. There is even a type of pipe that is smoked...
Is a soldered fitting better then a threaded fitting?
Depends on what you are doing. soldered is for copper water lines. Threaded can be for water, gas, or anything else.
How do you install rolled copper plumbing?
Unroll it and use as you would normal hard copper. Compression fittings or soldered fittings.

Should i use copper or compression fitting on rigid copper?
If you are joining rigid copper pipes together, it is recommended to use soldered copper fittings instead of compression fittings. Soldered fittings provide a more secure and leak-free connection compared to compression fittings, especially under high temperatures and pressure.
What is the definition of a tie wire?
Copper wires soldered to the panel and twisted around a saddle bar.
What type of glue is used for copper?
No glue is used for copper. Copper wires and pipes are soldered together. This involves heating both pieces and melting a lead/tin wire into them.
What does c x c mean in plumbing?
Copper x copper, which means the fitting is sized for copper pipe and usually needs to be soldered unless it is a compression type fitting.
What grade of copper pipe schedule is used for entry water that is buried underground?
Underground I use K copper exclusively..
Is copper mined above ground or underground?
Copper is mined in pits ... which were underground at one point in time and are now above ground albeit at a lower elevation.
