I accidentally broke the sight glass in the 20 gallon boil kettle on the ToP tonight cleaning up. I will order one first thing tomorrow (Adventures in Homebrewing has them). Until it gets replaced, you cannot use this kettle as it will leak. You can still use a regular 20 gal kettle on the ToP if you need.
Apologies for the inconvenience.
I ordered the replacement this morming, hopefully we have some quick shipping and it's in house by this weekend. Apologies again.
So the replacement sight glass is sitting in the kettle, but I only had about 5 minutes yesterday and couldn't find the allen wrench in order to put it on.
