Recently I installed a Peerless Low-Flow Shower Head I had sitting around in my closet. The one I had previously installed was starting to not work well.
Originally I thought that the "Low-Flow" meant it was supposed to use less water. When I took the old head off though I look at it a little bit and noticed it said 2.5 gpm. The Peerless Low-Flow Head also uses 2.5 gpm!
I was confused by this since the Peerless is supposed to be more efficient than these other models though. So I'm wondering, are Low-Flow Shower Heads really Low-Flow? Should I really be looking for GPM and not what the packaging says on the box? Do you think I'm saving any water?
2-1/2 GPM is considered a water saver head. Same as 1.6 Gallon toilets. Many people complain that they don't like the low flow heads, but it depends on the brand. I have a Water-pik brand and it works great. It also has many different types of spray pattern.
If you have never made a mistake, you haven't done much.
