I tore down and cleaned my 525SS's last night, after assembly I had no leaks but the tap handles move so freely I am afraid they will just fall open. Before the cleaning they seems to have more resistance, not sure if this was just from crud or I reassembled incorrectly somehow. I tried tightening the bonnet nut all the way down but this seems to have no real affect on the open/close resistance. Am I missing something here?
