How deep does PEX have to be buried?

PEX pipes and all underground piping should be buried at least 12” to 18” below the frost line to protect the pipes from freezing.

What kind of water pipe can be buried?

High-Density Polyethylene (HDPE, often just “PE”) has become one of the most popular choices for underground service lines, thanks to its corrosion-resistance, durability, and competitive price. Some codes require that buried plastic lines under 2″ in diameter be PE (rather than PVC).
