moen aerator tool

Moen aerator tool to remove inner aerator using a 14mm socket. The socket is a tight fit, so no elephant feet... or you'll have to sand a little. Tighter is better though. The aerator shouldn't take a lot of torque to remove.

I've also included a ket for the outer collar. I'd take the aerator out first then the outer piece.

Of course, be gentle when using the key so you don't break any teeth off of it. The smaller one is a little stronger.
