Watersense labeled bathroom sink faucets and accessories that use a maximum of 1 5 gallons per minute can reduce a sink s water flow by 30 percent or more from the standard flow of 2 2 gallons per minute without sacrificing performance. Bathroom faucets have a more restrictive flow of 1 5 or even 5 gallons per minute.

Kitchen faucets typically have a maximum flow rate of 2 2 gpm. Most new kitchen faucets have an aerator the screw on tip of the nozzle on the faucet. Studies show that on average people open the faucet to a flow rate between 1 0 gpm and 1 5 gpm. Since the federal limit stands at 2 2gpm most modern faucets come with an aerator that limits the flow to 2 2gpm while also infusing the water stream with air to reduce splashing.
