These small plugs fit Big Berkey filters that were made in 2013 or earlier. Pack of 4.
Note: This product can not be shipped to Iowa or California because of certification regulations.
IMPORTANT: To make sure you get the correct plugs, please check the manufacturing date on your Berkey (found on the bottom of the upper chamber). If the two-digit number in the circle is 13 or lower, this means your filter was made in 2013 earlier and these plugs will fit. If it says 14 or higher, you'll need the larger plugs #100006048.
