In order to maintain a set pressure in the structure or reduce the high incoming water pressure, a pressure reducing valve is often installed. While commonly known as a regulator, the pressure reducing valve provides a lower, more functional pressure for distribution to the consumer, thus protecting the water supply system in the process.

PEX (cross-linked polyethylene) tubing was invented in 1968 by a German scientist named Thomas Engle and introduced to the U.S. around 1980.
