The nozzle seems to be plugged. I can't find the toilet brochure, of course. See it when I don't need it. But anyway. Hubby fixed all plumbing from winter freeze and now just trying to get fixtures working. So took nozzle for toilet off and it runs water strong, so the nozzle must be plugged. But it seems you can't screw off the ends. Is there a secret here? Or does one just buy a new nozzle?
