What a 1 gallon tank means for runtime

A 1 gallon tank holds more condensate than smaller reservoirs, so you empty it less often. In a damp basement, that can mean once or twice a day instead of every few hours. The exact runtime depends on room humidity and temperature.

Tank sizes and drain options in this range

Observed tank volumes in this slice include: 1.06 gal, 1.2 gal, 1.6 gal. Some units list the tank in gallons, others in pints or liters, but the physical reservoir is similar. All samples here also include a drain hose for gravity drainage.

A 1 gallon tank is a middle ground between small 35 oz reservoirs and larger 2.11 gal tanks. It suits a bedroom, laundry room, or finished basement where you want fewer trips to the sink. The tank is removable for emptying and rinsing.

1 gallon tank questions

How often do I empty a 1 gallon tank?

In a damp basement, once or twice a day; in drier rooms, less often.

Can I connect a drain hose instead of using the tank?

Yes, all units in this range include a drain hose for continuous drainage.

Is a 1 gallon tank heavy when full?

Water weighs about 8 pounds per gallon, so a full tank is manageable for most adults.
