re: JP Boil Water Advisory

Forgive my ignorance, do they take tests every hour or so in order to get the all clear at 25 hour or 26 hours, etc instead of waiting for it to fail and wait another 24 hours?

No. Every 24 hours.

The test usually comes back negative after the first test and the boil advisory is lifted.

BTW, JP does daily microbiological test on their distribution system. It’s very rare to find a positive test and have to issue a boil advisory. However boil advisories are standard operating procedure after repair.

Look, the pipe they use to repair leaks and such are just sitting out in the open is some JP yard. There is no telling how much bird and rat shite are in those pipes. Sure the ends should sealed during storage but that is not guaranteed and the contractors handling and installing the repair pipe are not thinking about aseptic technique. Thus the automatic boil advisory after repairs.
