Leak Rate Test
Internal Outlet Valve Leak
A leak of the outlet valve will be identified separately (internal outlet valve
leak) by calculating the difference between leak rate 1 and leak rate 2. If the
second leak rate is higher than the first one, this is due to a flow back through
the outlet valve.
