Pipe Materials
Can Different Types of Pipes Be Mixed in the Same Network?
Technically this is possible using dedicated transition fittings (like a copper-to-PPR adapter), but it isn't always the ideal choice because the difference in thermal expansion rates between materials can stress the connection point over time and increase the likelihood of a leak at that specific point. For partial repairs, it's best to match the original material type as closely as possible, or use a certified transition fitting suited to the pressure being used.
