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.
Soldered, compression, Filmac, ProBite
Solder can be used on any grade of brass or copper.
Copper tubing that is underground must be one complete piece.No connectors,no repairs.All fittings must be above ground.Also all underground copper tubing must be plastic coated to protect it from oxidation.
First off all.... copper is used for many things examples electrical cables,wiring and speakers and the answer is yes it is used for head phone connections
Copper (Cu)
No.
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.
Copper pipe is soldered. Steel pipe is welded. Plastic pipe (pvc) is glued. There is even a type of pipe that is smoked...
Depends on what you are doing. soldered is for copper water lines. Threaded can be for water, gas, or anything else.
Unroll it and use as you would normal hard copper. Compression fittings or soldered fittings.

Copper wires soldered to the panel and twisted around a saddle bar.
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.
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.
Underground I use K copper exclusively..
Copper is mined in pits ... which were underground at one point in time and are now above ground albeit at a lower elevation.
