Steam Systems under big mouth vent

Hi guys, I see a lot of people started using these. Up until now the biggest vent was a Gorton No 2. My supply houses don't seem to know anything about them. Does anyone have a link for where I can get these? Also, has anyone had any problems with leaking etc? (It looks like a steam trap). Obviously, always want to make sure things are tried and tested before we start using them.
Thanks in advance.

    You can get it here: https://www.amazon.com/Barnes-Jones-Big-Mouth-Vent/dp/B01F26P13C/ref=sr_1_1?ie=UTF8&qid=1542309900&sr=8-1&keywords=barnes+and+jones+big+mouth or by calling Barnes & Jones and ordering directly.

    I've installed several around my town, and so far there's been no complaints, only praise. They spit a tiny amount of steam while closing, but then seal perfectly tight. They have an o-ring seal inside to ensure this.

    The only thing they don't do that Gortons do is close against water -- so so long as they are mounted high enough to never see water (28 inches above the water line for each psi of boiler pressure), they're really good.

    Yep. Learned that one the hard way with a faulty water feeder... Upside, I got a free shower out of it..

    Hope it wasn’t a hot steam shower!
    OK go thanks for the help

    Good reason to have 2nd pressuretrol as a interlock wired ahead of the feeder. If it overfills and it's set to 1.5psi then as long as the gorton is over 3ft above the pressuretrol it will shut down the feeder. Assuming you re using a vapor stat set lower.

    Hi gang— I keep reading about this height warning, but doesn’t the equalizer keep the column from rising on the return or am I horribly misunderstanding? Thanks!

    The pressure in the boiler-(even ounces) will raise the water in the wet returns 1.75 inches per ounce of pressure.
    If you connect a hose to the boiler drain, and mount the open end high, and fire the boiler, you can see the elevated level by moving the open end downwards until water come out of the hose. Using a hose made up of clear tubing, it is even easier to see the level changing. The difference between the at rest boiler level, and the firing level in the tube in inches divided by 1.75 equals the pressure in ounces.—NBC

    So why should I shell out for a 0-3 PSI gauge, when I could just make my own out of a piece of clear hose, and probably would be more accurate as well?

    Because a 0 - 3 gauge won't spew boiling water everywhere should the Pressuretrol fail.

    Ah, good point...

    Or you do it so the "tube" is closed up with a long sight glass set up. This is for pressure control, but for just "seeing" pressure you can ditch all the controls.

    Or just buy a gauge. ;)

    You can also make a U tube that will shut off using pieces of cork at the top as a valve.

    The Dwyer Slacktube does this.


    Personally.......I'll stick to using Magnehelics for continuous measurement.
