A:
I apologize for the inconvenience; however, the unit will not work if there is any type of cap on the water jugs. In order for the unit to work properly you must remove the cap off of the water jug.
Please give us a call at the number below and we will be more than happy to answer any additional questions. Thank you for your time and patience.
