Occasionally, something will happen in the installation process of your Black Berkey purifiers, and you may strip the threads. If that happens, your Black Berkey purifiers will no longer be able to remain in your system tightly secured.
One of two things has likely occurred at this point. Either 1) you have stripped the threads on the wingnuts, and 2) you have stripped the threads on the stems of the Black Berkey purifiers.
Before you order new parts, you will want to check to see which parts you actually need. To do this, you will want to take the other wingnut (the good wingnut that is on the other filter(s)) and attempt to use it on the filter that is having the problem. Either it will work or it won’t.
If it works, then your problem was the old/bad wingnut. You will just need to order a replacement wingnut. You can order that here: https://9ghealthfoods.com/shop/replacement-washers-for-bb9-filters/
If it does NOT work, then the Black Berkey purifier is the culprit. Unfortunately, there’s no way to replace the stem, so you would need to order a replacement Black Berkey purifier. You can order those here: https://9ghealthfoods.com/shop/black-berkey-filters/
