Steaming Return Tank

Steam gauge

Q: I notice a lot of steam rising out of the return tank in my boiler room. Is this normal or is something wrong?

A: This is not normal. The problem could be caused by one or more steam traps not operating properly. The temperature on the outlet side of the trap should be 75 degrees F less than the temperature on the inlet side of the trap, if the temperature is the same you have a “blow through.” You can check the temperature on each side with wax sticks or paper indicators. The wax sticks or paper indicators come in varying temperature ranges, so choose the one closest to the temperature of the steam your boiler is generating.
