Brewed a batch last night and went to cool it down by turning on the faucet for the wort chiller. Went back to the garage and as soon as I started looking for leaks my vinyl hose that bridges the chiller and the garden hose exploded!!! Scared the s*** out of me and damn near blew my ear drums. Apparently a kink in the outflow hose built pressure and it had to give. Let's just hope none of the water made it into my boil kettle.
I was brewing when it as -30 outside and we finished one batch and it was a few minutes before the next batch was done and the waste water hose froze outside. When we turned the water back on, it blew the hose off on the outflow side and blew boiling water all over my friend. Lesson learned!!
