It seems the new filters, get clogged really easily and you have to wait till it drains and shake it a bunch put it back in and it starts to drain again and it seems to keep happening over and over again just to let you guys know. (Cerra Customer Service: Some source water has more particulates and contaminates to filter out which can cause the filter to clog up sooner then expected. Taking the filter out and shaking it up can improve water flow and extend lifespan of the filter.)
