Can and should are two totally different things.
I did this once, and will never do it again. My first brew day on the ol' Sabco and at the new house was in 3F degree weather. The hose bibs on the house are both about 75-80' away from the brewing location of the garage while the laundry room is a short jaunt inside, through two doors. I attempted to use the exterior hose bibs at first, but the hose froze solid in about 30-40 minutes. We had to drag that inside and let it thaw over the floor drain (btw - trying to move a 100' frozen hose, full of ice, is not fun). Brew day presses on and we obviously need water. I hatch a harebrained plan to disconnect the washer from the hot and cold water, running another hose from the laundry room inside to run the chiller with cold water and then clean up with the hot water, saving our hands from freezing during the hour long clean up.
Here's what really happened:
- The chilling went great. Hit 55F with a single pass. (Yes, I brewed a lager for the first beer at the new place on a new brewery.)
- We switched over to hot water for cleaning. POOR DECISION. Burnt my hand with hot-a$$ water, got pissed at myself for thinking it was a good idea, went back and switched the water source (all while leaning over the dryer), and went back to freezing my fingers off.
- Finished cleaning, went back in to hook the washer back up, and discovered that in my haste I had not fully tightened the hose onto the cold water. Water was about 1/2" deep in my laundry room. UGH.
- Cleaned up the huge mess I made.
- Called my plumber the next week and had hot & cold water plumbed into the garage with a sink. Never again.
