If I knew then what I know now, I would've bought a brew kettle with welded fittings. From what I understand (and please correct me if I'm wrong), welded fittings don't leak (provided they're welded correctly), whereas weldless are more likely to leak, if the o-ring(s) give out, which they eventually do due to wear & tear.
I'm shopping for a wort chiller, and I would love to make my existing kettle work with a counterflow chiller. So. I have a 30 quart / 7.5 gallon kettle & I want to find someone who can weld the threaded coupler into the kettle for me, at a reasonable price. What's "a reasonable price"? You tell me.
I live in the Niagara, ON region. Does anybody have someone they use in this area who has done an excellent job in the past?
This has been on the back burner for a very very long time. I've decided not to pursue home brewing. There's just no way of getting the answers I need in a timely manner. I've posted on this & another (American) beer brewers website, but still haven't figured out how to get welded fittings.
Oh well, I guess I gave it the ol' college try and I'm better off just buying my beer. Shame though. This looked like a really fun hobby. But thank you for your suggestion.
If you decide to try again post questions and someone will get back to you!
