I’m glad you have this product. Before I had this, we over filled our berkefeld a couple of times. It was always hard to judge the water levels. I’m too short to see in. I wish I didn’t have to pay so much for this product. Seems like it should already come with this to help see the water lines.

The berkefeld Stainless Steel water spigot works better than any system we have used. Has easy to see water level and the ON-OFF handle is so easy to control the water flow into glasses and pitchers. Highly recommend.
Tamara D. –
Totally worth it!

Works as advertised

The product is excellent! I actually own 2 berkefeld systems because they are the best! But I had some questions recently and customer service is literally non existent! Phone number just goes to voice mail where I left many phone messages for several days and left an e mail, but got no response from any of them.

I love it! It helps me see where the water. It was quick and easy to install. Thank you!

Love the stainless spigot and being able to see where the water line is makes me more in love with my berkefeld . It is worth the cost. Product came quickly too.

I received my display spigot in a week and feel fortunate it wasn’t caught up in the short supply issues. I did have to put the Fluoride Filters I need on a wait list as they apparently did get affected by the supply chain issues.

The sight glass is very convenient. I think it’s a must have!

After so many years of having to tip my duke Berkie to see if it needs to be filled, I can finally see how much water is left before I refill.

As for me and my house, this glass spigot is a “must have” with a duke berkefeld filter. We have given several duke berkefeld filters as wedding gifts but the glass spigot was unavailable at the time. Thankfully, we are now able to bring our gift to completion by giving them the glass spigots, too!
Carol C. –
sure makes is easy to know what the water level actually is.
Ligia –
This spigot is very practical. You can see when you need to refill. I love it.

No problem

This is not a necessity, but a great add-on for my prince berkefeld . I can see from across the kitchen if I need to filter more water without having to lift the upper chamber. It makes a great product even better.
MELISSA –
good price
Cheryl –
Makes so easy to know when to fill my duke berkefeld
Raven C. –
This is truly handy because of the tiny space I have to keep the berkefeld . I can see level and add water as needed without pulling out the entire unit.
Paul G. –
In our opinion.. it makes using berkefeld a lot easier .. it’s nice to know how much water is in Unit without taking off lid or having to take it apart .. If would be nice if it were included in purchase price in that it’s a must have.
thomas nichols –
Love this see through spigot, sure recomend it highly!
Christy Blackman –
Should have bought this when I originally bought my prince berkefeld …saves me from having to lift up the top chamber to see how much water is in bottom chamber. It originally leaked when I first installed it, but that was my fault because the rubber washer was squished at a funny angle…just loosened assembly then retightened and all was good.
TMH –
The spigot works as intended but the collar that holds the glass indicator in place came broken. Instead of asking for an exchange I have lived with the defect instead of waiting for an exchange. I would have preferred better quality control.
David Russell –
Make it so much easier to monitor your water level.. I have one for each of the four filters I’ve purchased.
Donald –
A must have for your berkefeld . Great addition to a great filter system.
Mike J. –
I bought this at the recommendation of others who own a berkefeld and I am happy that I did. Without it there is no way to know what the water level is inside the berkefeld , so this is very handy. I have had no issues with it at all and there was never any water leakage like I have seen some people mention, it just needs to be screwed in correctly.
Michelle E. Mclendon –
Works great with my berkefeld . No leaks, no overflowing.
Michael Quinn –
Works great no problems.
Michael Pigg –
A must have for anyone buying a berkefeld !
Nancy Hicks –
Cheaper cost then buying through berkefeld ! Thanks! I like this feature for my berkefeld as it makes it easier to see how much water is left. It would have been nice to receive insallation directions with it as it leaked when I first installed it. I ended up finding a You Tube video to tell me how.
Michelle Calandro –
berkefeld is the best product out there an they stand behind there stuff too, made in the usa!
Nancy C. –
Easy to install and works great when tightened properly.
Mildred Carpenter –
This was just what we needed to make our berkefeld complete. If you overfill your berkefeld just once, you will know why the Sight Glass Spigot is so necessary!
middle-way –
Great addition to my water filter! No more running over. Thanks
MtnReady –
I’ve been able to stop my berkefeld from overflowing. This is a great item.
nicolas –
The sight glass is a duke help. I have overflowed the berkefeld twice now, but that is because I was not paying enough attention. I know that the sight glass has prevented many many overflows. It works great and was easy to install. We tried using the hardware that came with the berkefeld and it’s spigot, but you really need to use the hardware that they send with it. (They actually knew what they were talking about! Go figure.:)
Nancy C. –
Purchased this Glass Water level for our prince berkefeld and it works great..very happy 🙂
mojowurkn –
Makes it easier!
Michael Webb –
Our water filter sets too high for me to see how much water is left. I was having to guess how much water was left in the lower chamber and sometimes didn’t guess right so we would run out of filtered water. The glass spigot takes the guesswork out and now I never overfill the upper chamber.
Moises –
Works great. don’t worry about those who talk about the hole in the top. You have to REALLY overfill it for it to be an issue. I fill my duke berkefeld to the tippy top with two white filters in the upper chamber, and it comes nowhere near getting to the top of the tube.

Works great.
