I have a Grohe kitchen faucet 30 211 that had a bad valve. I have tried 2 new valves (#46 374) but I alway get a leak from the center of the new valve. The leak does lessen with tightening of the 30 mm nut, but does not go away. I use a silicone grease and the cartridge does align easily. I have tried Installing with and without a copper sleeve. I’m sure I am doing something wrong but cannot figure out what. Any suggestions?
