Copper pipes are practically sold in two general types – the hard and soft variety. Both types come in an array of sizes, ranging from as small as ¼ inches up to as big as 2 inches. The size of the pipe that you need to acquire will immensely depend on their application. For instance, if you will use them for tub and shower supply lines, ½ inches copper pipes are the most suitable choice. But if they will be used for kitchen and bathroom taps, 3/8 inches pipes are highly recommended. Meanwhile, ¼ inches pipes are ideal for toilet supply lines. Remember that pipes with larges sizes are typically used for water supply connections.
Aside from the fact that they come in varying sizes, copper pipes are also available in 3 different thickness. Each of which is designed to satisfy a particular plumbing purpose. They are normally marked by letters so they can be easily differentiated from one another. On that note, the three types of copper pipes according to thickness include following:
- Type M – These copper pipes are the most common type sold in the market today. Although they are relatively thin-walled, you are assured that they still meet standard building codes. In fact, they are widely used for creating water lines or connections for residential use. Type M copper pipes are marked with a red M lettering for easy identification.
- Type K – This is perhaps the thickest type of copper pipe available. They are mainly used for running pipes from main water lines to a meter or underground water pipes . They are usually marked with an orange K lettering.
- Type L – These are thicker walled copper pipes that are marked with a blue L lettering. They are normally utilized when making water connections in exposed areas.
Overall, copper pipes can certainly be used in almost all types of plumbing applications. But since they are available in different thickness and sizes, it is critical to determine your exact requirements.
