Very few water meters here but went to a house today previous " contractor" told client her "pump" was broken and He couldn't get parts it would have to be replaced. So she saw my ad and wanted a second opinion I went there and it was a Neptune water meter it clicks and makes a loud winding sound I helped install some of these meters a couple years ago... Not this one thou ares were mostly outside at the curb this is in the house . Of course its sharkbited on to Old copper and I wouldn't dare turn the Old gate valve upstream of it off... Any sugestions its three years Old? It sounds horrible.. that same subdivision over chlorenated there water last week. Can't see a connection but don't know much about water meters?
