During rough-in you must pressure test the water piping. Which is a typical acceptable test for the water distribution system before concealment?
a.No test is needed
b.Fill and eyeball for leaks only
c.A water or air pressure test held at the required pressure for the required time with no drop
d.Run all fixtures at once for one minute
Giải thích
The water distribution piping is proved with a water (or air) pressure test held at the required pressure for the required duration with no pressure drop, confirming there are no leaks before concealment. Skipping the test, merely eyeballing, or briefly running fixtures does not satisfy the required pressure test.
