3 Ways to Tell if Your Humidifier Float Valve Needs to Be Replaced

Your humidifier float valve may need replacing if any of these conditions are present. Check out these 3 ways to tell if it is time to replace your humidifier's float valve.

1. No Humidity Entering Your Room Air

The humidifier float valve may be clogged with mineral deposits from your water. Remove and clean the float valve, and reinstall it. If the water is still not reaching the vaporizing unit, the float valve is defective and must be replaced.

2. Humidifier Is Overflowing

Sometimes the opposite problem may occur with a faulty float valve. In this case, the float valve may be stuck near the top of the water reservoir. Remove the float valve and check its connector to ensure it moves freely as the water reservoir level rises and falls. If the connector is damaged or worn, replace the float valve.

3. Worn Float Valve

Inspect the humidifier every 2 months during the winter to ensure the float valve orifice and its rubber support buttons are making a tight seal. If the valve entry and the support buttons are worn down, a tight seal will not be achieved. Water can flood out of the reservoir and damage the humidifier's electrical parts. Replace the float valve if parts look worn out upon inspection.
