Both are rated above the typical water pressure levels found in public water supply systems. Unless municipal rules state differently, copper pipe for indoor domestic water supply lines can be type M or L. International building codes, on the other hand, accept the use of L, M, and K pipes for water delivery. Some local plumbing laws only permit the use of type L in residences and prohibit the use of type M. However, the International Building Code approved both L and M and type K for use as water supply pipes. Only type L is permitted in some municipal codes, while type M is prohibited. Type L has thicker walls and can withstand higher pressures. The water system pipes in residences are Types M, and L. The only kind of copper pipe that can be buried is Type K, or greenish copper pipe, which is commonly used to convey water into a home. Applications of Copper PipesĪlthough all pipe types are acceptable for plumbing, DWV should not be utilized as a water supply pipe because it does not have a pressure rating. For example, the inside diameter of half-inch type M is 0.569 inches, while type L is 0.545 inches. Because of the varied thickness of the walls, the internal diameter varies by type. Similar types and sizes of copper pipes have the same outer diameter, allowing them to be connected with the same fittings. Because Type L has thicker walls, it weighs more and consumes more copper, resulting in higher manufacturing and transportation costs. The wall thickness of Type M three-quarter-inch pipe is 0.032 inches, while Type L is 0.045 inches. The wall thickness of type M half-inch pipe is 0.028 inches, while type L is 0.040 inches. Half-inch and three-quarter-inch are the most popular sizes. The fundamental distinction between types M and L is the thickness of the wall and the pressure rating. Under the same conditions, pipes having thicker walls will endure longer than tubes with thinner walls. Generally, the greater the pipe thickness – not the diameter – the more water pressure it can handle than thinner pipework. Therefore, the kind of copper tubing specified for any purpose, the setup, the conditions of service, and the regional building code requirements may all be influenced by the internal or external fluid pressure. The copper pipe’s internal diameter (ID) is defined by the pipe’s wall thickness, which varies depending on the pipe type. This is true of all three common new pipe types: K, L, and M. A 1/2-inch copper pipe, for example, has a 5/8-inch outside diameter. The nominal size of a rigid copper pipe is always 1/8 inch less than the actual outer diameter (OD). Pipes, on the other hand, have a width and a thickness, which might be perplexing since a large tube with thin walls is less able to resist pressure. Water must also be pumped at relatively high pressure from the ground to a showerhead or above the kitchen or bathroom.Įach pipe category is stress-tested in a laboratory to evaluate its performance under different water pressures. Under pressure, water flows through pipes. L copper pipes, for example, will have blue writing or a thin line of blue paint on them. M pipes can be adopted for water supply and heat distribution.Ĭopper pipes have a narrow strip of color and text on the outside to identify the type of pipe. ĭWV pipes are mostly seen in older residences and have been phased out in favor of plastic pipes that are less expensive and easier to work with. DMV pipes aren’t utilized for water delivery and have no pressure rating, which means that they can bursteven at 1 PSI. Water is delivered via L copper pipes, whereas heat is delivered via M copper pipes. K copper pipes are the only form of pipes installed underground. Type L copper pipes are thus referred to as blue, while type M copper pipes are referred to as red. Type K is represented by green, type L is represented by blue, type M is characterized by red, and type DWV is represented by yellow. The hue helps to distinguish the copper pipe type. The letter identifiers are also used to match the color of a pipe to the type of pipe it represents. The wall thickness of a pipe is determined by its size. The relative pipe wall thickness is partially indicated by these letters. Varieties L, M, DWV, and K are the four types of copper pipe offered by manufacturers. This blog will attempt to explain all you should know about the distinctions between the four categories of copper pipes, when each should be used, and how to determine if you should use L or M copper pipes. Because L pipes are more pricey than M pipes, M copper pipes are frequently preferred. When applied to household water supply or structure, L copper pipes endure longer than M copper pipes. L copper tubing is thicker compared to their M counterparts. L and M copper pipes differ in thickness. Bottom Line Difference between L and M copper pipes
