ecoflow wave 2 drain extension

I made this so I wouldn't have to keep emptying the drain manually during humid times.Now my drain just hangs through the window next to the exhaust.I had contact with the support team from Ecoflow and the said that de drain pump can pump the water upwards to a maximum of a meter heigh. the models are designed to be used with Push-in air fittings as seen in the picture the tube is 12mm in diameter and the threaded coupling uses a G 3/8 thread
