      Just a guess, but maybe when the wind blows very hard by your plumbing vent pipe (probably located on roof) it causes a negative pressure to build in the pipe. It could be a siphoning effect. Try installing some sort of baffle on the vent pipe.

      Hey Chap, what you have is one of the EIGHT reasons a TRAP can loose its seal (Ask any 1st year apprentice)

      What is happening is called “oscillation” wind effect going down the vent terminal?
      NEVER EVER EVER EVER put a baffle on a roof vent terminal as in some climates you could cause hoarfrost.

      What you could LEGALLY do is either put a vandal proof vent cap on that allows full circulation Or a return bend which still will allow full circulation without any possibility of back drafts.

      Hopefully some 1st year apprentice will jump on the over 7 reasons a trap can loose its seal.

      By the way this is very typical especially in mountain areas OR in NYC high rise area’s

      The rush of air down a 4″ vent terminal will pull the trap seal right out.

      If you E mail me privatly ILL be happy to explain the techinical aspects of it after all we dont want everyone knowing this profession huh?
