Up to what height can PEX tubing be used for hot and cold water distribution in residential dwellings/buildings?

Two stories
Three stories
Four stories
Five stories

The correct answer is: Three stories

The use of PEX tubing for hot and cold water distribution is commonly regulated by local codes, which often align with national standards. In Massachusetts, PEX can typically be used for plumbing systems in residential buildings up to three stories in height. This limitation is primarily based on considerations such as water pressure and the ability to maintain consistent temperatures across the plumbing system. While PEX is a flexible and durable product that has many advantages, including resistance to corrosion and scale build-up, its applicability in multi-story buildings does have limitations to ensure effective performance and safety. Therefore, using PEX tubing for building heights exceeding three stories may introduce complications in terms of water supply, pressure management, and temperature regulation.
