Problem
No condensate Float is damaged or filled with
is discharged condensate
(blocked) or
The float is sticking to the orifice
discharge is
Orifice, screen or piping is clogged
poor
with rust or scale
Steam locking has occurred
Flow exceeds trap's rated capacity
The trap operating pressure exceeds
the maximum specified pressure, or
there is insufficient differential pressure
between the trap inlet and outlet
Steam is Rust and scale have accumulated
discharged around the orifice or under the float
or leaks from
Scratches on the orifice
the trap outlet
Float is deformed or coated with scale Clean or replace the float
(blowing)
Trap is installed above the maximum
(Steam leakage)
