Maintenance Tips: Tool Guide To Change A Cache Aerator

If you’ve ever had to change a cache aerator, you’ve already learned the hard way that not all aerators are identical.

About cache aerators

Cache aerators have been used by OEMs since 2006 and are WaterSense Listed. This hidden aerator threads directly (and disappears) into the faucet spot, making it vandal proof by design. Removal and installation is easy with the correct cache key.

A cache aerator, or sleeveless faucet aerator, is removed and installed using a variety of keys. Like an Allen wrench, it will be worthwhile to keep all cache aerator keys on the same ring or carabiner.
