Arrived on site and customer stated that they had trouble taking off the garbage disposal which they were trying to replace. I went ahead and was able to remove the existing garbage disposal and replace it with the one that they had purchased. I also checked the outlet to the disposal with the multi reader, and I did not get a reading of 120v. I checked a few other outlet outlets around the kitchen, which seemed to be working fine. I had called dispatch to set up an appointment so an electrician can come out and further diagnose the outlet. After Disposal was installed, I checked all areas and made sure disposal drained without any issues.
