I have tried replacing a Grohe 46 374 into my kitchen faucet. I always end up with the cartridge leaking through the center when turning the faucet off. It will lessen with tightening but does not resolve. The cartridge seats nicely in place and I used some plumber’s silicone. I have tried two new cartridges. Does anyone have any suggestions? Thank you
