(6) Inspecting for leaks in the fill-tub plumbing

If pressure leaks are discovered, run the test again after fixing the leaky areas.

• Do not apply additional pressure to the equipment.

Install a valve on one end of the fill-tub plumbing. (Valve open.)

Install a booster pump on the other end to feed water into the fill-tub plumbing.

Once the air has been removed from the fill-tub plumbing and it has been filled with water, close the installed valve.

Inspect for leaks.

Inspection pressure and time: 43.5 psi (0.30 MPa) for five minutes or longer.

• Use a pressure meter that suits the pressure being checked when inspecting the pressure.
• Be sure that there are no leaks or pressure drops across the gauge.

Do not apply pressure to the equipment itself.
