Water heating typically accounts for 14 percent of your utility bill. Repairing leaky faucets, insulating the water heater tank and hot water pipes, and installing low-flow faucets and shower heads can result in significant additional savings.
Shavings can pile up around a hole being drilled, making it hard for you to see what you are doing. To prevent this, push the point of the drill bit through a 4-in. strip of masking tape, then draw the tape up the bit so it will clear the work. Fold the strip lengthwise to bring the sticky sides together. The tape “wings” will act as a fan to clear the surface.
