Metal RuptureGuard Disk
Replacement
The easiest way to remove the metal RuptureGuard™
disk from the valve assembly is to carefully pierce the
dome with a screwdriver. Gently pull the disk out of the
body of the valve by using the hinge area on the other
side of the disk’s dome. Avoid scratching the interior of
the valve body.
