Is that whay you brew in ?
No I brew in the 8 gallon pot I got on amazon, it also has a ball valve. I’ve had that pot for about 4 years. But my brewing has evolved (buy once, cry once). I used to brew extract and the 8 gal pot worked for me, now I brew all grain and use that keg for my hot liquor tank and the 8 gal pot for the boil. Before I made the shift to all grain I would use the 8 gallon pot to fill my mash tun, and add water back into the kettle (8gal) after mashing, now I don’t have to. I use gravity and plenty of hot water to sparge and collect enough mash to boil for 5gal.
I would say the kettle is the least of your worries when it come to brewing, focus your time and energy on equipment you will really need and value.
Heck, 12 years ago I bought a pot a Walmart and just siphoned my material. I got the biggest pot I could find.
