Moen-Sounds like French Euro Fascists, so what can we expect.
We went through the same thing when we build our house 12 years ago. We had a plumber come in, and even he could not remove the GreenWeenie flow restictor without destroying the faucet.
At least with the Al IdiotCrookPerv Gore, 1/4 ounce per flush toilets, you can flush the damn things 3 or 4 times to get the job done. Not so with a faucet, where you want a copious, steady, generous flow of water and you want it now.
We have named the third flush on the low water volume toilets, the FUAG Flush.
Do what I do. When I get a shower or sink faucet of the Algore variety, I take my drill and bore out the plastic choke inside. My shower will put a hole in you.
