    Default Grease trap question?

    Grease trap question?


    I just had a call from a local food place that uses someone else.

    The owner told me that he just had his small inside trap pumped out and right after the trap lines backed up?

    He was told it was an air bubble. The other company took the cover off and burped it. it was not an air bubble.

    I have never hear of such a thing in my life ?

    Has anyone else ?

    So the company cleaned a line and it was good. My thoughts are they didn’t clean a baffle or knock one off.

    But I can see a clogged trap becoming open and free flowing knocking off some sludge or chunk in the inlet side and backing up.


    Just my thoughts…

    But the air bubble thing boggles me ?????

    I also have seen lift station pumps air lock or vapor lock but this is just a plan ole in and out trap.

    I've worked on many grease traps in my career and I've never heard of, nor encountered this. Here in New York City the waste lines are all vented after the grease trap and the sink line going to the grease trap must have an air gap between the waste line and fixture. This is to prevent sewage from possibly backing up into the fixture, contaminating any food or utensils in the fixture.

    Sounds like someone was blowing air bubbles out of their 6 when they said that...

    Just dealt with a greasezilla 600 not to long ago and the tank itself needs to be vented to prevent such a thing for happening and that info is coming direct from the manufactor.

    depending on the type/ manufacturer of the trap and how it was installed, it is possible.

    Rockford has a grease trap that has a vent tap on the side. It will not fill from empty with the vent plugged.

    The Rockfords im referring to are in floor. GF series to be exact.

    The problem with that design is it's impossible to NOT install that vent in the horizontal position unless you roll it up immediately. The vent then plugs with grease and needs jetting regularly.

    A properly Installed & Cleaned grease trap won't need "Burping."
    These are examples of improper installation and improper cleaning...

    That's why I said "..... and how it's installed...."

    Yes, it's possible, but it usually means something is not right.
