I've wanted to do this for some time. I am not using the thermometer port in my brew kettle, so I thought I'd add some fittings to create a whirlpool to help settle solids out and speed immersion chilling.
I had to do some plumbing shenanigans to get the fittings through the unused thermometer port, since the inside is not threaded.
This is MoreBeer's 15 gallon stainless brew kettle.
