Troubleshooting
NEVER apply direct heat to the float.
The float may explode due to increased internal pressure, causing accidents leading
to serious injury or damage to property and equipment.
When disassembling or removing the product, wait until the internal pressure
equals atmospheric pressure and the surface of the product has cooled to
room temperature.
Disassembling or removing the product when it is hot or under pressure may lead
to discharge of fluids, causing burns, other injuries or damage.
If the product fails to operate properly, use the following table to locate the cause and
remedy.
Problem
Cause
Remedy
No condensate is
discharged
(blocked) or
discharge is poor
The float is damaged or filled with
condensate
Replace with a new float
The orifice opening, screen or piping
are clogged with rust and scale
Clean parts
The X-element is scratched or
damaged
Replace with a new X-element
The product operating pressure
exceeds the maximum specified
pressure or there is insufficient
pressure differential between the
product inlet and outlet
Compare specifications and actual
operating conditions
Steam locking has occurred
Perform a bypass blowdown or close
the trap inlet valve and allow the trap
to cool
Steam is
discharged or
leaks from the
outlet
(blowing)
(steam leakage)
Build-up on the seating surface of the
orifice or rust and scale build-up
beneath the float
Clean parts
Damage to the orifice
Replace with a new orifice
The float is misshapen or has surface
build-up
Clean or replace with a new float
Improper installation orientation
Correct the installation
Trap vibration
Lengthen the inlet piping and fasten it
securely
The air vent valve seating area of the
X-element and/or air vent valve seat
have surface build-up or are damaged
Clean the air vent valve seating area
of the X-element and/or air vent valve
seat or replace with new X-element
and/or air vent valve seat
The element retainer on the optional
lock release valve is in the lowered
position (the lock release valve is
open)
Raise the element retainer (close the
lock release valve)
Steam is leaking
from a place
other than the
outlet
Gasket deterioration or damage
Replace with new gasket(s)
Improper tightening torques were
used
Tighten to the proper torque
Erosion of the body or the cover
Replace with a new product
Float frequently
becomes
damaged
Water hammer has occurred
Study and correct the piping
NOTE: When replacing parts with new, use the parts list for reference and replace with parts
from the Maintenance Kit, Repair Kit, etc. (Please note that replacement parts are only
available in pre-packaged kits.)
