Question about Bemis 697 400 Humidifier
The unit we have is approximately 7-8 years old and we have replaced the filter and wick assembly nearly once a year. Despite this preventive maintenance the unit is not working properly. The Fan will run continuously, but the water will not drain from the tank into the reservoir and the wick will dry out. When I remove the tanks the suction is such that water can no longer flow from the tanks. If I turn the tanks upside down(cap up) the tank will then allow air to enter the tank and equalize the pressure. When the tank is placed back into the unit water will flow until pressure becomes such that it becomes air locked again. We have cleaned the caps to no avail. Do I need new caps for the tanks, or is there some other issue? Very Dry in PA.
Sounds like new caps should solve it, but have you tried soaking the old caps in vinegar overnight? these guys are not the only ones, but they have the correct caps in stock at a pretty good price http://www.marbeck.com/humidifier_parts_bemis.html hope this helps :)
