Flush Flush
NOTICE NOTICE NOTICE
Failure to flush prior to material curing in the
system will result in damage to system and may
require replacement of all system parts in contact
with the material.
NOTICE NOTICE NOTICE
If the zero cavity pressure relief valve has been
used to relieve pressure, the valve must be flushed
to prevent material hardening in zero cavity relief
valve. If that is not sufficient, remove, disassemble,
and clean the valve then reinstall.
• Flush if the materials in the system are about to
reach their cure time.
• Flush any time the flow rate starts to decrease as
this is a sign that material is starting to thicken and
cure.
• Always flush the system at least twice, draining
all material flushing agent between flushes then
replacing with clean material flushing agent.
• For some mortars, it is recommended to flush
every 3 - 5 kits. Others can run continuously
without flushing. See material manufacturer
recommendation.
