+1 on the shooting everywhere if you are not careful!
+1 the shutoff valve being very useful
One thing if you have an on demand hot water heater. If you use the shut off valve, be ready for a few seconds of cold water, followed by a few seconds of warmer water before it returns to prior temp. Just be ready and it's all good!
