How to Remove Faucet Aerator That is Stuck – with Pliers

When you want to replace or clean an old faucet aerator but it won't come off by hand, you need a wrench or pliers to remove it. In this article, I show you how to remove it with water pump pliers.

All modern indoor faucets, whether in your kitchen or bathroom, have an aerator. A faucet aerator is a small porous fitting that threads onto the spout of the faucet. It has tiny holes that diffuse water to make it flow more softly without splashing. This is why the alternative name for a faucet aerator is a splash filter. Some people also called these faucet add-on devices flow restrictors because they restrict the flow rate of water, this helping to reduce water consumption as a result.

Over time, a faucet aerator may clog up with debris and may need replacement or cleaning. Sometimes you may just want to take out an older aerator and replace it with a new one. You can even replace a stock aerator housing with a decorative one. Many people do it as part of interior decor.

Generally, a faucet aerator is easy to remove by hand but sometimes it can get too tight especially due to calcification and you may need to use a tool. In this article, I show you how to use pliers to easily remove a faucet aerator from any faucet. You will not need a wrench; just a of water pump pliers or channel lock pliers.

  5. Check to see that the aerator gasket came out aerator assembly. If not, insert your finger inside the faucet and pull it out. You can use needle-nose pliers if you have one handy.
  6. If your faucet has a recessed aerator, use a faucet aerator remover tool. Alternatively, insert the sharp tips of needlenose pliers in to the grooves of the recessed aerator and gently twist counterclockwise to unlock it.
  7. Pop in the new aerator and rubber gasket into the old housing. The gasket should sit on top.
  8. Thread the new aerator assembly onto the faucet and tighten it by hand.
