The test for potable water supply is no leaks under ______ ______ pressure.

The test for potable water supply is no leaks under ______ ______ pressure.

• A. normal working pressure
• B. house pressure
• C. static pressure
• D. maximum pressure

Answer: (A)

The test for a potable water supply is meant to show that the piping and fittings can handle the pressure the system will routinely experience in use. That means verifying there are no leaks at the normal working pressure—the pressure you expect when water is being drawn through the system during typical day-to-day operation. If the system holds under this service pressure, it will perform reliably in real-life conditions. Static pressure is the pressure when water isn’t flowing, which doesn’t reflect the stresses during normal use, and testing at maximum pressure would not represent typical service conditions. So evaluating leaks at normal working pressure confirms the system’s integrity for everyday operation.
