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 1/2 gallons per minute and water-saving showerheads will naturally use less than that. A popular water flow choice for a high-efficiency showerhead is 1 1/2 gpm.
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.
