Berkey Sight Glass Spigot


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.

Berkey Reviews

Should be standardReview by Rashi
Not sure why they don't include this as standard with the stainless systems. It may be to keep costs down, but I would increase the price, and then include this with all systems. I came back and bought this a month after owning the system cause I understood why it's such a benefit. (Posted on 3/19/14)

A Must!!Review by Mr. Sandman
Buying a berkey without a see through spigot is like buying a nice home without a garage. Sure, you'll live find without it, but once you do have it, you can never go back to being without it. (Posted on 5/23/13)

I would recommend this for all stainless systems if you're going to use the system daily. It's convenient and a nice finishing touch. To address the other reviewer, the threaded portion is a little short, but I didn't have a problem securing it and did not experience any leaking either. (Posted on 11/14/12)
Good idea, flawed design, possible work-around...Review by Rachel Bruce
This as an excellent idea and necessary accessory for any Berkey user. However, there are two problems:

1. The length of the threaded portion onto which the nut is screwed is way too short. It is at least half as long as the threaded portion on the original spigot that comes with the Berkey itself. Not much room for both washers and nut.

2. Despite tightening as much as possible, soaking washers in olive oil and following the instructions to the letter, the sight glass spigot leaks from behind the washers. No amount of adjustment fixes this.

I found a possible work-around...use the white beveled washer and a black washer from the original spigot instead of the two black washers.

You must put the white beveled washer onto the spigot threads FIRST with the beveled portion facing the exterior of the Berkey itself.

Insert the spigot into the hole, then add a black washer on the inside, PUSH REALLY HARD from both sides and screw the nut onto the threads. There is not much room to screw on the nut, and it may take two people, but it has been 6 hours and I have filled the Berkey full with no signs of leakage whatsoever. Will report back after 24 hours.

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!!
