Copper Pipes :

Copper pipes are commonly used in the construction industry for residential water supply lines and sometimes for drain and vent lines. Copper pipes can be manufactured as soft or rigid copper and they offer excellent corrosion resistance and reliable connections.

Type K Copper Pipe :

Best for: Main water lines, underground installations. Type K copper pipe has the thickest wall of all the common types. It is used for water distribution, fire protection, oil, HVAC, and many other applications in the construction industry. Type K pipe is available in rigid and flexible forms. It is recommended for main water lines and underground installations because its thickness helps it withstand the pressure from backfilled earth in trenches.

Type M Copper Pipe:

Best for: Branch plumbing lines. Type M copper pipe is thinner than both type K and L copper pipe. It is a common choice for repairs, replacements, and extensions to interior water supply lines. But Type M copper is not always allowed by plumbing codes in all areas, so check first with the local building authority. Where allowed, it is often favored for residential work because of its relatively low price—a thinner pipe wall means less copper and thus a lower price. It is a favorite of DIYers, who find it easy to cut and fit. But it is not available in a flexible form, as is type L. Type M copper pipe is identified by red markings.
