Should you add more water into the upper chamber of your berkey for filtering?  At a quick glance, the berkey sight glass spigot allows customers the ability to see the water level in the lower chamber of their stainless steel unit. This glass tube can be rinsed out with soap and water when you decide to clean your system.

There are 3 sizes available (shown in image left to right):

  • 7.5" - For Travel Berkey and Big Berkey systems
  • 10" - For Royal Berkey and Imperial Berkey systems
  • 13" - For Crown Berkey system

Note: All systems come standard with a basic spigot and this sight glass is considered an aftermarket upgrade.

Product Questions

I am ordering the Big Berkey for $258 and want the sight glass spigot also but do not know which size to order. Can you help me please?
I am trying to install the glass spigot to my British Berkenfeld. The directions say to put a black washer on the screw on the outside , thread it through the container and put a black washer on the inside before screwing the nut on the screw. There isn't room on the inside to do this. Help!!
Can the stainless steel spigot be used with the sight glass spigot?
How often should I clean the Bentley water filtration system? Specific instructions for cleaning available?
My Big Berkley is great and no leaks. But the water level does not show in the glass tube. What can I check?
