The rupture disk on a low-pressure appliance should be:
a.Adjusted to a higher setting for leak testing
b.Replaced with a plug for service
c.Removed during recovery
d.Kept sound and never bypassed

Test pressure must stay below its typical 15 psig setting, which is why 10 psig is the leak-test limit. Tampering with it endangers the technician and the equipment.
