    I would think that is unlikely but I'll ask.

    Amazon does not have an inventory an this time (Nov 15, 2017). Has anyone heard when they will get another shipment of Barnes & Jones Big Mouth Air Vent?
  • Circa1902Circa1902 Member Posts: 20
    Following this thread to see if I can get Big Mouths soon, if not I will have to go with the Gortons.
  • I think very soon. There are plenty in stock now, but Peter The Great has left the building and Andrew has taken over. I think Andrew just needs to find the time to get them over to Amazon...

    I showed a picture of one of my installed Big Mouth vents to the students in the class I give in NYC and one of them busted out laughing because my guys "put a trap where an air vent goes". There was no convincing him the BJ-3BM was an air vent and it generated a lot of discussion, especially when I explained that every steam trap starts out as an air vent. Good stuff.

    Well I guess technically you are both right, the Big Mouth would function just fine as a trap. I don't know how well the silicone seat would cope with typical debris though.

    Question... maybe it's been answered before).... is the Big Mouth pretty much a radiator trap turned sideways?
  • SailahSailah Member Posts: 822
    Sort of. The body is custom machined to accept an O ring seat which is necessary to get a true dripless seal. Our first go at it we used the stock seat machined into the body from the larger Mepco 1" trap. This has some saying that the vent would drip a few drops so we decided to go to a silicone o ring. We also made the orifice much larger than a typical 3/4" radiator trap.

    But essentially, other than what I described above, the Big Mouth is a radiator trap turned sideways.

    A request please:

    From this point forward if you have a question about the Big Mouth, please email Bill at [email protected]

    PLEASE, do not call Andrew, he was spending all day on the phone and it was interfering with his work. I deleted his phone number.

    Thanks

    I can imagine he must have ben going nuts.

    I used to be sitting at my desk at 6:30 every morning and I got more work done in that 90 minutes than I did for the next 8-1/2 hours because of the damn phone. This was back in the day when if you were out on the production floor you would have to walk by a doxen workbenches to reach a phone. That made it hard to get things done on the floor.

    I'm sorry to ask my question here, but I'm not sure it's worth the new thread.

    Can Big Mouth be installed not vertical but horizontal? (I just don't have enough room...)

  • FredFred Member Posts: 8,370
    No, has to be Vertical. If you don't have enough room, go with the Barnes and Jones Varivent. It is a shorter main vent and adjustable.

    why does it have to be vertical? I think it's preferred but I don't think it's life or death

    @ChrisJ , If I recall correctly, @Sailah said they would drip if they are not vertical

    Yes
    But I don't think it's the end of the world. Guess it depends on what's under it

    As long as the disc is flat in X direction it will work. So if vent is placed like a "trap" it would be ok, but not on edge.

    And the opening should face up or down? I'm sorry, I don't know how "trap" is usually placed like.

  • SailahSailah Member Posts: 822
    Sorry.

    If the vent is orientated with the blue label facing upwards (like a radiator trap), it will function fine. However it won't allow condensate to drain as effectively as if the tailpiece were pointed down like you see most have installed.

    Where it won't work is if vent is clocked in such a way to where water will allow to pool in the vent. If you laid vent down on a table, with label facing you, female NPT threads facing away from you and tailpiece pointed to one side or the other, water will pool in the vent and cooling the disc. This orientation wont work

    I'll work on it, and thanks! I think I'll be down in NYC a lot more with SteamIQ based on the interest we have in your great city.

    I usually drive down and back in a day which doesn't leave a lot of time for socializing!

    ...The stockings were hung by the flue pipe with care in the hope that a Big Mouth soon would be there...

    You'll not be disappointed, it's a very nice unit!

    Has anybody got a link to these vents
    Just want to see what they look like dimensions etc.
  • Steve_210Steve_210 Member Posts: 585
    OK found it on Amazon .
    I presume they could also be used as crossover traps in a two pipe system
    Just need to be careful with System balance

    Barnes & Jones makes a specific crossover trap based on Big Mouth but without silicone seat. Has brass seat.

    PN: BJ-2CR 1/2" Big Mouth Crossover
    BJ-3CR 3/4" Big Mouth Crossover

    You need to order direct from factory, it's a bit like ordering Animal Style from In-N-Out Burger. Speak in hushed tones, you will get puzzled looks, but just say:

    Hi guys. I currently have a gorton #1 main vent and I just ordered a big mouth from amazon. The main vent is about 30ft away from the boiler and I’m told that the gorton is way too small and my rads are not getting hot quick enough. How do I install the big mouth? Just put some Teflon around the threading and screw in like a regular radiator air valve?
  • KC_JonesKC_Jones Member Posts: 4,383

    The big mouth vent is in 2 pieces. There is a tail piece or spud and the vent itself. They are joined with a union nut. To install you separate the 2 halves, screw the tail piece (circled in blue) and with the union nut (red) on it, into your main with PTFE tape or pipe dope. You will need a 5/8" Allen wrench to tighten it. After that attach the vent (black) with the union nut and tighten, do not over tighten the joint. I'd suggest hand tight and maybe an 1/8-1/4 turn with a wrench.

    I need an Allan wrench? It looks like a basic channel lok pliers to just twist it on? What exactly is the Allan wrench tightening?
  • KC_JonesKC_Jones Member Posts: 4,383
    The allen wrench goes inside the pipe, the ID of the pipe is a hex not round. There won't be room for pliers.

    after taking the vent apart you will see that the spud had a 5/8" female hex where the allen wrench is used to tighten the spud into the femaie NPT pipe fitting. I've heard some people use a corrrectly sized hex bolt head to insert into the female hex to tighten it if no 5/8" allen wrench is available (tighten using pipe wrench on bolt shaft after head is in the allen recess).

    I guess I have to see it to understand it because I can’t envision this.
