I received this as a Christmas present from my husband, eight months ago.  It makes the best cold brew I have ever had and extremely simple to clean, except for a recent issue.  The plastic threads on the base which connects to the hose attachment to the spigot are completely stripped already.  You have to clean this every other brew lest you get an oil build up in the spigot and hose.  
I cant find a replacement part anywhere!  I love this device but I am not throwing  away a perfectly functioning glass and stainless decanter due to an inherent plastic issue.  Post consumer waste.  Can you send me a replacement part?  Please
