Southside Plumbing came out to investigate a sewer gas smell in the women’s restroom. Upon entering the room, it was noted there is a floor drain in the ADA stall. The floor drain was found to have an empty P trap, so the trap was filled with water. The drain was inspected for any kind of trap primer but one could not be found. (The surrounding area was searched as well) A waterless trap seal was installed on the drain to prevent foul smells in the future. A trap seal was installed in the men’s room as well.
