DRINKPOD Bottleless Water Cooler Countertop Water Dispenser Hot & Cold Modes For Offices and Homes

The installation does not take a long time, but the water didn't come out from the dispenser at first.I thought my item was a defect, but the product was fine. It was just a problem with my cold water pressure.My cold water pressure is weak, so my water source couldn't pass through the "800" valve (backflow valve?).However, after I bypassed the "800" valve as in the pictures, the cleaned water started coming out from the dispenser.The filtered water should come out without any power sources, so you don't want to power it on until the water comes out from the dispenser.
