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.)
