Go with the Flow, the Low Flow


Installing low flow showerheads is a simple way to conserve energy. According to Energy Star, “You can purchase some quality, low-flow fixtures for around $10 to $20 a piece and achieve water savings of 25%–60%.”

So, what is low flow? Well, new federal regulations require that showerheads and faucets do not allow the flow of more than 2.5 gallons of water per minute (gpm) at a pressure of 80 pounds per square inch. However, before 1992 there were some showerheads up to 5.5 gpm! Therefore, low flow showerheads and faucets have water flow at a level below 2.5 gpm. If your showerhead is from before 1992 you may want to replace it, or click here to see the Energy Star article on how to determine the flow rate.

There are two types of low flow showerheads: laminar and aerating.

Laminar – These are showerheads that have streams of water that come out individually.

Aerating – These are showerheads that combine air with water, which creates a sort of mist.
