Thank you for your question regarding the Delta 6-Setting Shower Head and I am happy to assist you today.
The maximum flow rate for this shower head is 1.75 gpm (gallons per minute) @ 80 psi (pounds per square inch).
If you are more familiar with using a model which dispenses 2.5 gallons per minute or higher, you may notice a difference in the amount of water being dispensed.
If you would like to test your model to ensure that you are receiving 1.75 gallons of water per minute, please fill a pitcher or bucket for one minute and measure the amount of water to be certain the model is dispensing the full 1.75 gallons.
We do manufacture shower heads which have a 2.5 GPM flow rate. If you are interested in a shower head with a higher flow rate, please visit the link below and under the 'Type' tab, please select 'Shower Heads' and under the 'Max Flow Rate' tab, please select '2.50 gpm, 9.5 L/min':
I hope this information is helpful and please feel free to give us a call if we can assist you with anything else going forward at 800-345-3358.
