After cleaning or changing the cartridge, the output is too slow at first,but become strong a moment later,and purified water drips out from the water outlet even when the tap is turned off
There is still air in the Countertop Water Purifier housing after cartridge installation. Firstly, to bottom up the Purifier; then unscrew the housing a little and let the water overflow from the interstice (between the bottom and the housing); after that, tighten the housing and stand on end the purifier.
