  1. Dave Rongey says:

    Hi Mrs M,
    What I suspect is that there is a problem with the back draft flapper. Where the exhaust duct connects to the housing of the vent unit there is an adapter which should have a flapper. The flapper is designed to open up only when there is exhausting air flow. The flapper also prevents a back draft by staying closed when the vent is not in use. If the flapper is missing or is not mounted into the adapter properly then it will not work correctly and this may be why you are noticing a draft.

    Our home is 30 years old with recessed heat lamp vents in the bathrooms. What did we do wrong when they were installed to have a draft when the wind blows? They are vented into the ceiling and then to an outside fascia. If that was a correct way to install them then how to we stop the loss of warm air when the vents are not in use?

  3. Dave Rongey says:

    Yes Jim, those V-Shaped wires support the trim piece for the recessed light. Carefully squeezing theses wires together will allow the wires to be removed from the guides inside the recessed light. Once the trim piece is remover then you will have access to the light bulb. Be sure to use the same watt bulb to prevent the recessed light from over heating.
    Here is a link to one of my videos that shows this process:

    My daughter has a light fixture over her bathtub/shower, and the bulb has burned out. I cannot figure out how to replace the bulb. I guess you would call the fixture “recessed”: The glass globe extends about 5 inches down from the ceiling, and is flat on the bottom. There is a trim ring as well at the ceiling. I can pull the fixture down to expose the inside, and can see the little v’shaped wires on two sides that hold the fixture in place. Beyond that, I am at a loss. Can the globe itself be removed somehow to replace the bulb? I’ve turned, pulled, twisted, spun, etc…but no luck. Thanks for any help!
