I use a 25ft copper immersion wort chiller, with a faucet stainless sink adapter. When I received it, the vinyl connections to the copper arms leaked at the stainless clamps. I tightened, but water slowly trickeld at the connection points. WTF. Thinking that I wasn't getting enough focal pressure to create a water tight seal, I pulled the tubing out to the edge of the stainless clamp, and tighened as much as I could muscle. problem solved.
takes about 10-25 minutes to chill work to pitching temps, depending on the time of year. I place the chiller in the kettle at flame out to sanitize, if not doing a flame out hop addition. If doing a flame out hop addition, then I'll add with 5 minutes left in the boil. I wish there was a way for me to use the hot/warm water that is dumped out the other end of the chiller, but I don't have a garden to water (well, not one that's close enough for this to be feasible), I don't have a washing machine to load up. Something I'll do when I get out of the condo.
