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.

 

WARNING 

 

 

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.

 

CAUTION 

 

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 bimetal is damaged 

Replace with a new bimetal 

Steam locking has occurred 

Perform a bypass blowdown, 
or close the trap inlet valve 
and allow the trap to cool 

The trap operating pressure exceeds the 
maximum specified pressure, or whether 
there is insufficient pressure differential 
between the trap inlet and outlet 

Compare specifications and 
actual operating conditions 

Steam is 
discharged or leaks 
from the outlet 
(blowing) 
(steam leakage) 

Clogged orifice opening or rust and scale 
build-up beneath the float 

Clean parts 

Scratches on 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 bimetal air vent valve surface and/or 
the air vent valve seat has a build-up or is 
scratched 

Clean or replace with a new 
bimetal and/or air vent valve 
seat 

The bimetal is damaged 

Replace with a new bimetal 

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 

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 as part of a replacement parts kit.
