HOW IT WORKS
The most common complaint in bathrooms spare rooms with drains etc. That floor drain MUST have water in it or you get stinky smells and if there is no water then bugs come in.
The most common cause of sewer gas odor is when the water evaporates out of an unused or seldom used sink p-trap or floor drain, allowing sewer gas to escape.
Sewer Gas SolutionsTM eliminates sewer gas infiltration into buildings by creating a non-toxic, long-lasting layer which prevents water in plumbing traps from evaporating.
