Customer called us out for multiple fixtures backing up in the house. The mainfloor hallway bathroom was experiencing backups ups in the bathtub and in the sink. Previously the daughter’s bathroom downstairs was experiencing the same but not at this time. I double checked that the sewage ejector pump was working correctly. The back ups for the main floor hallway bathroom were both cause by the drain stoppers catching hair and forming gunk. I recommended clearing the tub drain stopper and running a tub gun down the overflow to clear any obstructions and removing the sink stopper and p trap and clearing any build up. Customer greed. I started with the sink and removed the stopper and the ptrap cleaning both throughly. I then pushed a paper towel down the stopper assembly to clear any build up on the sides. I put it lol back together and tested for leaks. I then removed the stopper and the over flow on the tub. I removed all hair from the drain and ran a tub gun down the line to clear any
