What is a Caché faucet aerator?
Our › Caché aerators are "invisibly" installed into the faucet spout. You can recognize them by their blue seal. A Caché aerator will only fit if you have a faucet with a special bore, and it can only be replaced by a Caché aerator of the same size. › Here we show you how to find out which size you need.
They are available with different stream patterns, flow rates and › water- and energy-saving features. Some models have an adjustable angle or offer effective limescale protection thanks to the so-called SLC function.
Aerators should be cleaned or replaced regularly – at the latest when limescale becomes visible or the stream is no longer attractive.
Removal and installation of the Caché faucet aerator
There is a suitable service key for removing and installing every size Caché aerator. In the video, we show step by step how the Caché aerator can be easily replaced on your bathroom or kitchen tap.
If the aerator cannot be removed
If you do not have a suitable key to hand, or if the Caché aerator is already too calcified, there are several alternatives. It is also worth trying these methods if you have another type of › faucet aerator beside a Caché that is stuck.
The soak method
Step 1: Preparation
To use the soak method, you will need a limescale remover, a balloon or small plastic bag and some adhesive tape.
Step 2: Soak
Pour the solvent into the balloon or plastic bag, attach it to the tap with the adhesive tape so that the Caché aerator is completely covered by the solution. Leave the aerator to soak for a few minutes to dissolve the deposits.
Step 3: Remove deposits
After soaking, remove the balloon/bag and the adhesive tape and wipe off the excess solution. The deposits should now have softened enough so that the Caché aerator can be unscrewed from the faucet spout using a service key.
Our friends at aerator.com show you how in this video.
The WD-40 method
If the aerator is stuck due to very heavy calcification, WD-40 can help. Follow the three simple steps (see below).
Our friends at aerator.com also have a video on this.
Step 1: Applying WD-40
Spray a generous amount of WD-40 onto the Caché aerator. Make sure that the affected areas are thoroughly covered and allow the WD-40 to dissolve the limescale.
Step 2: Be patient
Wait about five minutes so that the WD-40 has enough time to soften the deposits.
Step 3: Removing the aerator
After the exposure time, you should be able to turn the aerator counterclockwise using the appropriate service key and remove it effortlessly.
The screwdriver method
If neither the service key nor the two previous methods work, only "brute" force will help. You will need a screwdriver and two screws. Attention: Your aerator will no longer be usable afterwards!
You guessed it: there is also a video on this method from aerator.com.
Step 1: Attaching the screws
Carefully drill the screws about half a centimeter into the opposite sides of the aerator strainer. Make sure that the screws are fastened inside the strainer structure and not on the outer ring.
Step 2: Removing the aerator
Once the screws are in place, use an adjustable wrench or pliers to grasp the screws and twist counterclockwise to loosen and remove the aerator. Note that this method will damage the aerator, especially the strainer, and it will need to be replaced afterwards.
Step 3: Damage assessment
If you use this method, get a new aerator beforehand. You can find aerators in various retailers and online stores that stock plumbing products. In the USA, you are sure to find what you are looking for at › aerator.com.
Replacing the aerator is worthwhile
If you are unable to replace the aerator using the installation key, there are various alternatives available to you. Whether the soak method, the WD-40 method or the screwdriver method – with a little patience and the right procedure, you can replace the Caché aerator and thus improve the stream and the appearance of your faucet.
