Faucets are rated in gallons per minute, and that flow rate shapes how the faucet feels to use and how much water it sends down the drain. Most modern faucets are limited by law.
The rating
Bathroom faucets are typically limited to around 1.2 GPM or less, and kitchen faucets a bit higher, which balances use with conservation.
The aerator
The aerator sets the flow and mixes air into the stream, and swapping it changes both the feel and the volume.
The pressure
The rated flow assumes normal pressure, so low pressure can make a faucet feel weak even at its rated GPM.
The upgrade
A lower-flow aerator saves water, while a higher one is not allowed above the limit. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In St. Charles, local rules may add stricter limits.
The feel
A low-flow faucet with a good aerator still feels strong because of the air mixed in. The aerator design matters as much as the number.
