8. Operational Check
A visual inspection can be carried out to aid in determining the necessity for immediate
maintenance or repair, if the trap is open to atmosphere. If the trap does not discharge to
atmosphere, use diagnostic equipment such as TLV TrapMan or TLV Pocket TrapMan (within
their pressure and temperature measurement range).
Normal:
Condensate is discharged continuously with flash steam and the sound
of flow can be heard. If there is very little condensate, there is almost no
sound of flow.
Blocked:
No condensate is discharged. The trap is quiet and makes no noise,
and the surface temperature of the trap is low.
Blowing:
Live steam continually flows from the outlet and there is a continuous
metallic sound.
Steam
Live steam is discharged through the trap outlet together with the
Leakage:
condensate and there is a high-pitched sound.
(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For
this reason, the use of a steam trap diagnostic instrument such as TLV TrapMan is highly
recommended.)
