I would also like to caution people about heat+pressure. I had vinyl tube clamped to my wort chiller on both hot and cold sides. On the hot side, I connected a garden hose to the end of the vinyl to run the water out into the yard. I did not notice I had a kink in the hose. I started chilling and noticed drips on the cold side of the clamp. I bent over to tighten the worm clamp and right when my face was down by the chiller, the hot side vinyl blew up and sprayed me with 200F+ water. Got to visit the ER. Luckily no permanent damage, but I looked pretty bad for a couple weeks.
I'm not doom and gloom about this, but before you start pumping or turn on your garden hose, just do a once over about whats going on and make sure you're comfortable with your equipment. Burns aren't fun.
