Should I use type L or Type M copper pipe?

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.

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.

What is Type R copper tubing used for?

Tubing and Fittings in HVACR This type of tubing is used for hot and cold water supplies and the refrigerant lines found in HVAC systems.

What is Type K copper pipe used for?

Type K copper piping is available in both soft and rigid configurations and is used in applications that require high tolerance to pressure. These pipes are ideally suited for large-scale water supplies, compressed air pipes, fire protection systems, heating and cooling system use and industrial conduits.

What does ACR copper stand for?

Copper tube for air-conditioning and refrigeration field service (ACR) is designated by actual outside diameter.

Is copper pipe pure copper?

Copper pipe is almost pure copper manufactured to the requirements of ASTM B 42 – Standard Specification for Seamless Copper Pipe, Standard Sizes. The standard length for copper pipe is 12 feet. Copper pipe is suitable for plumbing, boiler feed lines, refrigeration and for similar purposes.

Is PEX better than copper?

We generally belive that Plumbing PEX Tubing is much better than Copper for most, if not all, plumbing systems. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. PEX Tubing is cheaper because it takes much less labor to install. PEX Tubing is quickly becoming the industry standard.

What type of copper is used for water heaters?

Copper pipe is available in rigid lengths or in flexible coils. 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.
