Stated.. last month used 26,000 gallons of water Tech notes.. came out to diagnose and unknown leak while on site we found the the main line going into the house was made out of galvanized metal and it connected to copper. The leak was from the galvanized to copper joint. Resolution.. recommend replacing galvanized main line with pex., pressure could not be taken due to leak in main, will need to check water pressure again after main line is replaced Status.. not complete Notes.. no visible clean out
