Anyone's Immersion Chiller ever corrode??
|
|
I brewed this past weekend and when I connected my IC I noticed that there was a hole in the very bottom of it with water pouring out. The hole is right where it touches the kettle.
It's only 3 months old and I can't for the life of me understand how this happened? It has a bit of green around the hole, telling me it's corroded. I'm wondering if it's because I don't typically purge the water out of it when I'm finished using it.
Anyone else ever have this happen? Got any idea on how to fix something like this? I attempted to solder over the hole, but I still have a couple pinhole's in it.

What conditions have you been keeping it in? I've never had this happen, but there are certain things that can corrode copper---so it depends on where you kept it.

Normally I just keep it on a wooden shelf in my basement. But there were a few times where I would store it on the shelf in my aluminum turkey fryer pot.
I wonder if this caused the reaction....

Sounds like it might be galvanic corrosion. http://en.wikipedia.org/wiki/Galvanic_corrosion

I keep mine in a plastic bucket after it has been rinsed and it has been dried. It sounds like what ma2brew says. Two difference metals.
You should be able to fix it with some flux and non-lead solder though.

I'd be inclined to cut out the corroded piece, clean it up, and solder in a coupler (if the hole is decent-sized).

Ah...yep, that wiki article described it perfectly. No more storing it in the pot. Thanks for the responses guys.
Stupid question : do they sell couplers for 3/8" copper tubing?

I don't even think you'd need a coupler. Depending on the size of the hole you could either try to simply build up some no-lead solder over it, or make a small patch from some more copper and solder that over it. It's not like an IC is pressurized.

They are sold as 1/4" pipe couplers. ID is actually 3/8". |

Yeah, rigid pipe fittings are rated at the INSIDE diameter of the pipe they are meant for. 3/8" copper tubing is actually 1/4" ID, so you need a 1/4" fitting.
