Identifying this trap

Could anyone tell me how this trap was designed to work?



Thanks Jim

    Trap

    Looks like it forms a water seal. No moving parts.

    Trap?

    Or vent?

    It's missing the thermostatic element

    you can see a bit of it still screwed into the underside of the trap's cover.



    Try Tunstall or Barnes & Jones for replacement parts.

    Trap

    It looks like the pipe inlet is lower than the outlet.

    i'm assuming thats an optical illusion

    or the air wouldn't get out of the radiator.

    Might be

    an outboard trap, like Illinois, Marsh and Sterling marketed back in the day.

    outboard trap

    works the same as any thermostatic trap, but sits sideways, thats all..theory was it would stay cleaner that way..

    outboard

    If I'm reading this right, they still have a thermostatic element, but tend not to collect debris?
  • gerry gillgerry gill Posts: 2,611
    yup, you got it.

    Tho, my experiance is they dont hmm old the steam back ss well as a standard trap.
