Pilot light

My condo building had a bypass installed in our boiler system few weeks ago. Since then, our pilot light has gone out twice. I've lived here for a year and a half, and we have never had issues with the pilot light before. Our thermocouple was replaced a year ago. Could the pilot light issues be related to the bypass installation?

    Depends on what you mean by bypass....but probably not. We need a lot more information, and pictures of the bypass would help. Why was the bypass installed?

    Is this a single boiler for a condo complex?
    If they cut into the piping they probably shut the gas off which would include the pilot.
    This has happened to me in that the T-couple would act up or not even relight.
    I have seen Utube of pro's who say they only get about 1 season out of a T-couple and just change it while there for PM to prevent call back.
    Old ones might last 20 years......new ones 2 years.....sometimes.

    Maybe just change it again.
