I am a Plumbing/HVAC Contractor and the type of fitting I always used for underground copper service pipe has been 3/4" (standard size for residential) brass flared fittings. A flared connection is a tight, secure connection guaranteed not to leak.
Yes, the compression fittings designed for copper work on both soft and hard copper pipes.
Unroll it and use as you would normal hard copper. Compression fittings or soldered fittings.
Yes they have compression joint fittings for copper.
No. You can use flared fittings with a flaring tool and soft copper pipe.
I believe it has to be flared as compression is not approved
compresion fittings usually work well if u have any problems use some sealing tape If you are going to have the pipes in wall use solder, any copper exposed you can use compression.
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.
properly installed - yes
It is not a good idea to use copper pipe with natural gas as any sulphur compounds in the gas can cause an oxide to form in the copper pipe. Often copper is used with propane. In these instances, soft copper tubing is usually used with compression fittings. The tools required are, pipe cutter and 2 wrenches.
Every hardware store I've ever been in keeps copper fittings.
No, copper pipes need to either be soldered, or connected with compression fittings. PVC cement will not bond with copper and provide a "solvent weld", it would be a very weak connection.
The quick and easy way is to use a compression "Shark Bite" fitting. It slips onto the copper pipe and creates a tight fit. Then use a threaded or pex flex adapter for your for the connection.Sweat on a male adapter to the copper pipe then just screw on the flex hose. You can also cut the pipe sweat on a tee then use a nipple and male adapter.
