Arrived on site client stated thier toilet slowly fills up and thier shutoff valve was unable to be turned by hand. Went over a few options with the client to either install a new toilet and rebuild the inside of tank with new shutoff valve. Toilet isn’t that old so client felt it was best to go with a partial rebuild today. Today I replaced the flapper, fill valve, shutoff valve, and supply line. Turned water back on to test for leaks and to test if all internals in the tank are working properly. Toilet isn’t now flushing and filling as it should.
