Q: Dear Ed: I have an old showerhead that I need to replace and would like some up-to-date water flow info. Can you please give me basic information on the amount of water a standard showerhead uses compared to a water-saving showerhead?

A: If you need to replace your old washed up showerhead, first check with your local building inspectors to find out the maximum showerhead water flow your town and/or state allows. This can vary depending on where you live, and some areas do have strict water use codes.
But, in many places standard showerheads can use 2.5 gallons per minute (gpm), and water-saving showerheads will naturally use less than that. A popular water flow choice for a high-efficiency showerhead is 1.5 gpm.
Never miss a local story.
If you go that low, I recommend you look for a showerhead with air-infused technology. High efficiency air-infused showers mix air and water together to create comfortable puffed-up shower drops that in turn can help drop your shower water usage.
