I have a 50 pint dehumidifier for sale. It has a reservoir, or an automatic pump system for drainage. It can be set in manual or automatic mode. It can pump continuously, or on a timer, or it can be preset for a humidity levels. I’ve had it 6 years, but it hasn’t been used in 4 years due to my new air conditioner. I paid over $200 new. It is in excellent working condition.
