1. Back pressure on condensate line.
2. Dirty steam trap - repair or replace.
3. Steam trap is wrong type.

Steam supply:
1. Steam pressure is too low (under 2 psi).
2. Steam main flooding due to boiler
discharging water with steam.
3. Steam supply not taken at top of main.
4. Distributor not level.
