alternative to water traps?

[MasterPlumbersKeymaster]

Does anyone know of any certified alternatives to traditional water traps to prevent sewer gas smells in my bathroom?Traditional water trap seals tend to evaporate when not used for long periods.

Have you considered a deep seal trap?

Have you considered installing a deep Main sewer trap?

Have you considered a fixture “plug” like a test bulb to be used when your on extended trips?
