I know on new construction a regulator is required at the meter but on all the older homes they do not have one. CS water pressure is insane like 130 in pebble creek and in woodcreek where I live about the same. Several neighbors have had flooded homes due to an icemaker or toilet malfunction due to the high pressure. Has anyone found a good plumber to install one at a reasonable price and not pull a permit to give the city more money on a problem they created !!!
