Final answer:
Copper water tube Type "M" can be installed within a building if it meets local building codes, which are designed to ensure safe and functional home systems. However, copper should not be used where it will connect with iron pipes to avoid rapid galvanic corrosion. Local building codes and compatibility of materials should be thoroughly considered.
Step-by-step explanation:
Whether copper water tube Type "M" can be installed within a building depends on the local building codes and the intended use of the plumbing system. In many More Developed Countries (MDCs), building codes are in place to ensure the safety and functionality of a house's structural and utility components, which include water supply systems. These codes often require that all materials used must not only provide durability but also prevent potential hazards, such as lead poisoning or structural damage.
The concern with using copper pipes, especially when connected with iron (Fe) piping as indicated, is the risk of galvanic corrosion. When two different metals, like copper (Cu) and iron, are connected in a plumbing system, they can react with each other in the presence of an electrolyte (like water), leading to this type of corrosion. One must consider the compatibility of materials to ensure the longevity of the plumbing system and avoid costly repairs or safety issues. A plumber may offer a low-cost option to use up their existing supply of copper pipe, but this could potentially lead to rapid corrosion at the joints where copper meets iron, so the overall long-term costs could be higher.
