I live in the mid south, and most water pressure regulators are
installed in front of the home and buried in the ground. After 10-15
years, they often fail and need to be replaced. That means finding them
and digging up so they can be replaced. My question is this: Why don't
they put a clay pipe or something similar around them and put a cover
over it? Water meters are installed that way. It seems burying it
makes replacement much more costly and difficult.
