TRAP SEAL is a specially engineered liquid that seals drain traps to prevent odors and preserve a sanitary septic seal. By ensuring traps remain filled with liquid, TRAP SEAL prevents sewer gases, odors, insects and bugs from entering through the trap and endangering the health of the inhabitants. Use whenever drain traps dry out, are not in use, are in remote areas or wherever odors are a problem such as floor and shower drains, sinks, toilets and urinals, water fountains and condensate drains. Ideal for use in empty or vacant buildings, schools, hospitals, stadiums, factories and marine applications.
