Contrary to popular belief, water-saving or low-flow showerheads don't reduce water pressure. In fact, a high-quality showerhead can actually increase the force of the spray by directing the water more efficiently.
A good showerhead will have a two- to three-gallon per minute flow rate, compared to five to eight gallons per minute for a conventional model - a difference of four cents per minute. The energy savings can be significant - a family of four, each taking a five-minute shower a day, can cut their water heating costs by $250 a year by switching to a water-saving showerhead!
You can test the amount of water your current showerhead emits: if it takes less than 20 seconds to fill a one-gallon bucket, you need a water-saving showerhead. Be sure to use COLD water for this experiment!
Drain the standing water from the existing showerhead. Without turning on the water faucet, open the shower level and let the water drain out.
Take your pliers or wrench and gently loosen the existing showerhead. If it's a little stubborn, wrap some first aid tape or a few adhesive bandages around the fitting to help you pliers get a better grip.
Unscrew the old showerhead and throw it away. Clean off the end of the pipe and dry it with the towel.
Take the Teflon tape and wrap it clockwise around the end of the fitting. This will help prevent any leaks or drips.
Screw on the new high-efficiency showerhead and tighten the nut with your pliers. Don't over-tighten, or you'll have trouble getting it off again.
Turn on the water faucet and open the shower to check for leaks. You'll have a strong spray that uses about half the water the old showerhead did!
