I have a leaky faucet and I presume it is a Moen because the aerator housing says Moen on it. The house was built in 2004 so I presume it is from that year. I cannot figure out how to disassemble it to save my life. There is no screw underneath the top cover, there is no screw on the side and it is two pieces so the whole thing does not unscrew together. See pics. Any help is appreciated.
