Most any facility experiences odors emanating from floor drains in restrooms, mechanical rooms, kitchens, warehouses, public areas, air conditioning and confined spaces. These are mostly due to the trap seal (usually water) in the trap evaporating over time, the trap seal not being replenished through trap primers or no additional water entering the trap, i.e. through wet mopping a floor. In addition, depending on the climate you live in, trap seals may evaporate rather quickly.
If the trap is configured with a trap primer, it may be that the trap primer no longer works. Or, in the case the trap was never outfitted with a primer, continuous replenishment of water to the trap is necessary to control odors, costing man hours, trouble shoot calls and salaries.
Enter EverPrime®! Simply add about one (1) gallon of water to the smelly floor drain, then add approximately three (3) ounces of EverPrime into the floor drain (on top of the water). Done! As long as there is no additional large amount of water entering the floor drain, flushing it out, EverPrime will last indefinitely.
