Symptoms
- Flow feels weak compared to older or other shower heads
- Head is labeled 'water-saving' or 'low-flow'
- Removing and cleaning the head doesn't meaningfully improve flow
- Flow is consistent, just generally low rather than sputtering
Likely causes
- CommonIntentional flow restrictor disc installed by the manufacturerFederal regulations require most shower heads to limit flow to conserve water, achieved with a small plastic disc.
- PossibleRestrictor combined with some mineral buildupEven a properly functioning restrictor can feel weaker if minerals have narrowed the opening further.
What to do
- Unscrew the shower head from the arm.
- Look inside the connector end for a small round or star-shaped plastic disc with a tiny hole in the center.
- Use a flathead screwdriver or small pick to gently pry the disc out, being careful not to damage the housing.
- Clean any mineral deposits from the housing while it's apart.
- Reattach the head with fresh plumber's tape on the threads.
- Test water flow; note that removing the restrictor will increase both flow and water/energy usage.
- If you rent, check your lease or ask your landlord before permanently removing a restrictor, since some properties require them.
