Low-Flow Aerators and Shower Heads

Installing Low-Flow Shower heads and faucet aerators is the single most effective water conservation savings you can do for your home.

Inexpensive and simple to install, low-flow shower heads and faucet aerators can reduce your home water consumption as much as 50%, and reduce your energy cost of heating the water also by as much as 50%.

This conservation of water and energy is not only good for the environment, but the savings in your utility bills will pay for the cost of the aerators within a few months. From then on, you enjoy continued savings.

How do I tell if I need one?Low-Flow Aerators

If an aerator is already installed on your faucet, it will have its rated flow imprinted on the side. This should read 2.75 gpm (gallons per minute) or lower. Replace if over 2.75gpm. If no aerator is installed, check to see if there are threads just inside the tip of the faucet. Most modern faucets are threaded to accept aerators.

Set a 2qt. saucepan on the floor of the shower and position it in the middle of the shower stream. With shower on full, count how many seconds it takes to fill the pan. If it takes fewer than 12 seconds, you could use a low-flow shower head. If you have a low-flow shower head installed, it should read 2.5 gpm or less.  Some modern water effecient shower heads from Moen rate as low as 1.75 gpm.


There are two types of low-flow shower heads: aerating and non-aerating.

  • Showers account for 22% of individual water use in North America.
  • Low flow shower-heads help reduce water waste, but don't lower shower head pressure.

Aerating - mixes air into the water stream. This maintains steady pressure so the flow has an even, full shower spray. Because air is mixed in with the water, the water temperature can cool down a bit towards the floor of the shower. Aerating shower heads are the most popular type of low-flow shower head.

Non-aerating - air is not mixed into the water stream. This maintains temperature well and delivers a strong spray. The water flow pulses with non-aerating shower heads, giving more of a massaging-showerhead effect.
