Is a low-flow showerhead a good investment for you?
One way to find out is to test how many seconds it take to fill a gallon of water held under your shower. The answer to this will determine if you will save water and water heating expenses with a change in showerhead.
All you need to perform this easy test is a bucket that can hold a gallon of water and a watch with a second hand!
1. Turn on the shower.
2. Hold a bucket under the water. Before doing this, mark off a gallon so you know when the bucket fills that far.
3. Using a watch with a second hand, time how long it takes the bucket to fill one gallon. Time how long it takes to fill the gallon bucket (or to the 1-gallon mark, 3.8 liters in a larger bucket).
If it takes under 20 seconds to fill one gallon, you will save a lot of water and water heating expense if you buy a low-flow showerhead.
