Sewer line usually gets pressure tested at ~5psi with respect to the specified ASTM standard.
In regards to the water service, usually from my experience, the city only performs test on water mains. Not sure on service lines. Usually it goes 1) Pressure test and then 2) Bacteria test.
Hope...
Is there any logic behind SC's delay? I mean the rest of the south and the entire west coast has released their results. It will really suck if they push this to Friday. I may give them a call again tomorrow if the results are not posted by 12 PM.
