Yup - those are the sight glasses! They come as a set. The top one is a little skinnier.

Seat cups sit inside the spigot. They should be replaced monthly. The sight glass gaskets sit on top and at the bottom of the sight glass on your urns. If not done often enough, the plastic will fuse to the glass and render it no longer food safe. We had to chuck an urn last month when my SM couldn’t get a sight glass up and it shattered, he then saw the bottom gasket had essentially crumbled and fused to the glass.

Ohh? They probably need it so badly! The first time I did the urns I actually needed tools. It took 2+ hours for 7 urns. Now that I do them regularly, it takes me 20 minutes to do 6. We’re down an urn.

The bottom gasket gets pretty gunky. I use one of the bristle cleaners to wedge the tip under and wiggle them free.

We swap them out completely once a month and rinse and wash on weekends (we are usually really slow and so we work through our CP list).

Oh no!! Okay, so what I did when I did them the first time was put several scoops of ice into the urns and then cold water. Turned the spigot so the cold water would go through the spigot. Cold water contracts metal. I also used tools from our toolbox. I used a wrench for the particularly difficult ones.

It’s also weird because the way you loosen and tighten is as if you’re the urn. So I always turn my back to it and figure out which way is left then turn that way.
