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.

Here in Alabamastan, the water pressure regulators are usually installed in the crawlspace or basement where the supply line enters the foundation wall. I've crawled under a few houses to replace or install one. ヽ(ヅ)ノ
