We have lost fresh water incoming pressure in our old house...
Is it possible to blow air pressure at the meter connection to blow open any obstruction that has clogged our old iron pipes... or run a snake wire into the line to clear a blockage?? tks

The answer is no you can't blow air or snake the pressure lines, I hate to tell you at this stage it is time for repiping, good luck.

Yep, you're going to be ripping some pipes out. It'll be fun!

Have you checked pressure at the meter to be sure valve at member is operating properly
