Sight Glass Spigot

(5 customer reviews)


SKU: SGS-7500 Category:

An accessory that adds style as well as function is certainly worth celebrating. Fitting the bill is ProOne’s sleek, stylish Sight Glass Spigot. Replacing the stainless steel spigot, the high-quality sight glass spigot allows an instant reading of the water level, so you know for sure when it’s time to add more to the tank.


Most gravity filters require lifting the upper chamber to see how much water is left in the lower chamber. But a quick glance at the Sight Glass Spigot is all you need to determine the accurate water level in your ProOne stainless steel units, including the Traveler+ or ProOne Big+ water filters. 


The ProOne Sight Glass Spigot also fits most competitive brands of gravity water filter systems including Alexapure, AquaCera, Doulton, and Patriot Pure. Additionally, it works with Berkey® water filter systems, including the Travel Berkey®, the Big Berkey® and Imperial Berkey® water filter.


This beautiful spigot with sight glass features a food grade 2-position plastic handle with a 7.5” sight glass stem. When it’s time to clean your gravity filter system, simply remove the view spigot, rinse the glass tube with soap and water, and allow it to air dry.

  1. Liz

    This is lovely. Heavy duty…no plastic except except the handle. Should stand the test of time.
    I have an Aqua Cera system which is the same as Big Berkey and this fit fine. The stem insert is thinner than the hole in my unit and I thought since it wasn’t as tight a fit water might leak, but they give you really good washers for inside and out and it works just fine. Before this I had the plastic competitors sight spigot and since it’s plastic it eventually leaked The company was great and offered return if it didn’t fit. The sight glass is 7 inches high..From the bottom of the inlet hole to top is about 9 inches tall.
    The heavy duty stainless is much better than the plastic one I got off Amazon. Very happy with purchase. Thank you

    I thought the price was high, but when I received the part in the mail I realized the price was very fair. The spigot is heavy duty and appears good quality. I’m glad I bought it.

    I didn’t hesitate to add this to my filter purchase and I’m so glad because I can’t imagine not having it!

    High quality and works as it should!

    ~~ HEADS UP ~~
    If your resevoir (lower bucket) is taller than the sight-glass, it will leak.

    We made a 5 Gallon bucket water filtration system (grandpappy’s) and once the water level increased past the sight glass, water leaked out.
    Didn’t realize how it worked before using it. Now I do, haha.

    So, we’re going to buy the non-sight glass version for our home-made 5gal system until I can find a longer tube.
