A very low-flow showerhead may feel uncomfortable. The U.S. EPA WaterSense specification limits flow to 2.0 gallons (about 7.6 liters) per minute and includes spray performance testing. WaterSense is a U.S. program; check locally applicable certification and plumbing compatibility too.

1. Check the existing showerhead connection, hose and hot-water system compatibility before purchasing.
2. Compare rated flow; WaterSense-labeled models must meet at most 2.0 gpm (about 7.6 L/min).
3. Cross-check the actual model in an official certification directory rather than trusting advertising claims alone.
4. Consider spray pattern, water pressure and any minimum-flow requirements of the water heater.
5. Follow the supplied installation instructions; stop if leaks occur and use qualified help for plumbing issues.
6. Manage shower duration too; actual savings depend on your former flow rate and habits.
