Customer called in about couple of issues. Customer mentioned that they’re getting sewer smell from laundry room and kitchen. Also would like for us to look at the disposal wiring. Checked underneath wiring and informed customer that it would be best to contact electrician to properly install an outlet for disposal. Saw that laundry drain has a single standpipe. Laundry line needs a p trap to prevent sewer smells. Sold repairs to install p trap and studor vent. Customer agreed to pricing. Went ahead and install p trap and studor vent. Old standpipe didn’t have a p trap in the ground. Checked for leaks and no leaks detected.
