Today, test your showerhead to find out whether you could be saving some serious water by installing a low-flow model. Here’s how:

• Put a bucket into your shower and fill it with 2.5 gallons of water.

• Mark the water level. Then empty the bucket.

• Put the bucket under your shower stream and turn it on full-blast.

• Time the flow for one minute.

• If the bucket fills past the 2.5 gallon mark, your showerhead is not low-flow.
