In legacy “low pressure” systems, regulators aren’t used at the residential end at all. Our neighborhood was recently upgraded to a “high pressure” system, and regulators were introduced, along with vents cut through the foundation to the outdoors. Our neighborhood was built in 1950. This system upgrade included replacing all the mains in the road as well.
