Low-flow aerator replacement.

Low-Flow Aerator Replacement

In February, I replaced each aerator in our bathroom sink faucets with a low-flow aerator that flows at 1.0 gallons per minute (GPM). Most faucets come with aerators that are easily replaceable and that allow for much greater water usage (usually 2.2 GPM flow).

Install the Low-Flow Aerator

When you look at your sink, there is a spot on the faucet where the water runs out.  That’s where the aerator will be.  Most likely, there’s some kind of clearly attached (by thread) retainer.

To do this, you’ll need to have large pliers and some kind of cloth on hand.  You’ll want to wrap the cloth around the stainless surface (nickel, etc.) of your sink before you put the pliers on it.    You’ll want to turn counter-clockwise as if you were looking up from the drain of the sink.  Once the basket (I’m sure there’s a real name for it) is removed, the old aerator will come out easily; just push it out.  Slide the new, low-flow aerator back into its place and reattach by screwing the basket back into the faucet. You can this, at first, by hand and then use your pliers.

I purchased three of these low-flow aerators and have been using them with great success.

The following video (on YouTube) shows how easy this really can be for a DIYer.


Readers should note that you may not want to change the aerator in your kitchen sink to a low-flow model. Cleaning takes much longer this way.

Otherwise, the arithmetic is simple.  1GPM vs. 2.2GPM, that’s a 54.5% reduction in flow.  Your habits won’t drastically change to accommodate more water and so you end up saving lots of water.

If you have any other tips or tricks for saving water, why not leave them in the comments section?  If they’re awesome enough, I might borrow your idea and write about it.
