I recently got the Tunze osmilator nano for my waterbox 20 cube. I bought it a week and a half ago and today i come home and the water level is low. I unplug and re plug in the ATO and the pump turned on but no water was being dispensed. I filled the tank back up manually but i left the ATO on just to check if it would happen again. The next time it turned on the same thing happened no water was coming out into the tank. The pump was running but no water was coming out. (my RO reservoir has been full this whole time.) Is there anything i can do to fix it or do i have to order a new pump? and is the pump really that bad that it would break within only a week and a half?
