Replacing a faucet aerator
When replacing a faucet aerator, the most important thing to ascertain is which model you are dealing with. We differentiate between faucet aerators with housing and those with integrated thread. It may be necessary to remove an existing aerator for cleaning, or to replace it with a new one – for example because the stream is no longer straight.

Replacing a faucet aerator with housing

How to replace a faucet aerator with housing:
  1. Loosen the aerator with a suitable key, then you can unscrew it by hand. You can see which key fits under › installation tools. Use a NEOPERL service key to avoid unsightly scratches on the chrome surface of your faucet. If a lot of limescale has built up on the aerator, it will take more effort to remove it.
  2. To select the correct replacement aerator, note the type of thread – female or male – and the size of the aerator. Helpful hints for choosing the right size can be found here: › aerators with housing. If you only want to replace the insert and continue using the existing housing (the metal ring), remove the washer and the insert from the old housing. Place the new insert and washer in the existing housing. Please note: the washer often remains in the faucet during disassembly. If the washer is still in the faucet, carefully remove it and insert the new aerator.
  3. Use the NEOPERL service key to install the new aerator.
  4. Now open the faucet and check that the aerator is correctly installed. If water drips out between the faucet and the aerator, reinstall the aerator or tighten it more firmly with the key.

Use the NEOPERL service key to replace a faucet aerator with integrated thread

Replacing a faucet aerator with integrated thread

  1. To replace the faucet aerator with integrated threads, be sure to use the appropriate key.NEOPERL service keys come in different colors and are therefore easy to distinguish. For more information on service keys, see › installation Tools.
  2. Place the key in the correct position. To increase the torque and prevent the serrations from breaking, make sure the indentations are interlocked. Then turn the faucet aerator to turn it on. If there is a large amount of scale buildup on the aerator, remove it as much as possible.
  3. When installing a new faucet aerator, again make sure that the key is in the correct position so that the threads will clamp properly. Otherwise it is easy to damage the plastic threads. Tighten the faucet aerator carefully so as not to damage the o-ring or change its position. Failure to do so will result in a leaky faucet. Wet the aerator with a small amount of water to ease installation. NOTE: For › CACHÉ models, screw the aerator only until it is flush with the faucet. Do not screw in completely to avoid damage.
For Coin Slot faucet aerators, you can use coins to help replace them. For more information, see › Coin Slot aerators.
