Model GXP33C - Keep in mind that the house this disposal is in is only used one out of every 3 weeks and was new Jan 2017. The galvanized grinding parts didn't help, at about the 2 year  mark the rotor rusted to the case and I had to free it with force to get it turning again. Now at the end of year 3, the disposal is leaking at the body joint where the top and bottom of the disposal join. Too bad it's only got a 2 year warranty. I will replacing this disposal with a different brand.
