Customer called us out for to replace a garbage disposal in the kitchen sink. The disposal they had was fairly new and showed no signs of rust. I turned it on and it sounded like something was stuck. I reached in and retrieved a large piece of plastic. Tested the disposal and it had no signs of a problem. Customer did not want to replace it anymore. I checked the water heater and house pressure. Water heater looked good but the house pressure was testing at 94 psi at one hose bib. The other hose bib was shut off and I could not locate the valve for it. I scheduled a service plumber to look at it next Tuesday.
