Copper pipe is available in three basic types:
* Type M
is a thin walled pipe. It is the most common type of copper tube sold, used mainly behind walls inside homes to route water from the service line and water heater to the fixtures. Trunk lines are typically run in 3/4-in. type M copper with 1/2-in. type M branching away to serve individual fixtures.
* Type 'L' (hard or soft)
for thicker wall tube, considered standard piping for use for water services inside and out, especially outside or wherever the pipe will be exposed.
* Type 'K' (hard or soft)
the thickest, used mainly between water mains and the meter, for heavy-duty vacuum pump lines and underground lines.
Type K: domestic water below grade (green)
Type L: domestic water above grade (blue)
Type M: hydronic heat (red)
Type DWV: wastewater (yellow)
