I need to replace the cartridge in my Grohe 20.655 Sinfonia two-handle lavatory wideset. This requires removal of the cross handle 1 and cap 5 (see the diagram and parts list). It is straight forward to remove the cross handle. But I can't figure out how to remove the cap.
Grohe tech support recommended a strap wrench. I've tried, but the strap wrench keeps slipping because of the bell shape of the cap. As a last resort, I'd have to loosen the nut under the sink. But it is very crowded under the sink and I want to avoid this route. Any suggestions on how to unscrew the cap? Thanks.
