A worn out aerator /adapter is a quick fix, as you're about to see. It’s also a great way to reduce your water usage and decrease your water bills. And when it comes to fixing it yourself, you're also about to see you're becoming a DIY expert.
Tools and supplies required: Adjustable Pliers
Turning counterclockwise, unscrew the old Aerator from the Faucet Spout. If your Aerator has been in place for a while, you may need to use Adjustable Pliers to loosen.
You should determine if your Aerator has Female or Male threaded connections before you go to your local home improvement store to find a replacement. If your Aerator or Adapter has threads on the outside, your Aerator is Male. If your Aerator has the threads on the inside, then your Aerator is Female.
Be sure to take your Aerator or Adapter with you to the store to be sure you get the right replacement part. Keep in mind that there are also dual fit Aerators (like the one shown in this image) and Adapters that can fit to either a Male or Female connection.
If not already in place, insert the Washer into the threaded end of the Aerator.
Turning clockwise, hand thread the new Aerator onto the Faucet Spout. Be sure not to overtighten. Finally, turn the water on to ensure there are no leaks.
