Should I use Type M or Type L copper?
Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine. The beefier Type L is often used underground, in hot water heating systems, for commercial plumbing and for gas line (where permitted).
What is the difference between L and M copper piping?
The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.
What is the difference between Type K and Type L copper tubing?
Type K is the heaviest. Type L is medium weight and used most often for water lines in homes. Type M is thinner and is used underground or for light domestic water lines if local codes allow.
Which pipe is best for water supply?
PEX piping is a flexible plastic piping that has become a popular selection in residential and small business applications. Although slightly higher initial cost, its minimal maintenance, and fast installation process make it the best pipe for water distribution inside a building.
Is L or M copper thicker?
Type L copper is thinner than Type K but thicker than type M. Type M Copper Pipe: Type M copper pipe is thinner than both type K and L copper pipe. Sold in both rigid and flexible forms, Type M is used most commonly for heating water services and vacuum systems.
What type of copper is used for boilers?
Type M is thin-wall copper pipe; Type L is thick-wall pipe. In some areas, Type M pipe isn’t allowed for delivering potable water, but it can be used for hot-water heating systems.
Can you ProPress Type M copper?
