mercerator pump

A couple of weeks ago I had to replace a broken gray water gate valve and the connecting base on the pump housing.  I disconnected the two wires going to the pump not taking note of which wire went to which connector (black and white coming down and then red and black after the splices going to the pump).   I put everything back together and went out for a couple of weeks of travel.   I came home with a full tank and went to unload and found the macerator did not work!  Motor ran but nothing came out, heard weird sounds coming from the tank.  I discovered that there was suction at the hose end!  The light bulb came on at that time.....I had reversed the two wires resulting in the pump rotating in the wrong direction.  Lesson learned...take note of which colors goes where before disconnecting!  All is A-OK now.  Ron G.

Oh yes!  Been there, done that with the pump running backwards when replacing my failed Sanicon pump with a Seaflo brand.  My story with all the details about it are HERE.  The wires coming off the macerator do not color-match the ones from the motor home.  I thought, black-to-black and color-to-color is the way it works so I initially wired it up that way.  I quickly learned during my testing that the pump ran backwards.

Glad to hear That I am not  the only "wing nut" out there!!!   Thanks for understanding Ron D.,  Ron G.
