Has anyone come across this return fitting in a Richardson System? If so, how does it work exactly?

    Does the spud that goes into the radiator have anything special about it?

    Works the same as the other version. The curved pipe dips down into the radiator section below the spud, where water collects. That creates the water seal. The hole drilled in the curved pipe is the air hole. The projection on the plug was probably to keep the vacuum check ball in place.

    My guess is they made that version to 1- display the name of the system, and 2- allow access to the air hole to clean it out without disconnecting the return fitting.

    But there is no check @steamhead. That’s the oddity.

    Never seen those ones, Danny. Were they taken apart before you? Were they causing a problem or you're just cleaning them up? Mad Dog

    Probably was originally and got removed or lost.

    Doing a kitchen/bathroom renovation. Installing radiant in these areas sadly and removing these few untouched rads. This garage can is being saved but not the rads :lol: wasn’t everything just so much cooler back then?!

    I honestly don’t think anything is missing as i removed 3 rads and they were all the same. I just think i found a gem!

    1925 @Steamhead. Maybe it was just a non-vacuum version, and that pin acted as a vacuum breaker? Or did the pin maybe act as or orifice? Maybe there are different size pins? The radiators I removed we’re all similar in size...maybe it’s like a model k system in that way?

    Thinking the orifice idea through a little more and i doubt that was the purpose, as the pinhole in the spud likely served that purpose (allowing the steam to condense before it entered the dry returns...

    I’m also thinking my non vacuum idea isn’t probable either, as the main vent in the Richardson System is where the vacuum occurred...

    In the Richardson, O-E, Kreibel and other systems, the check in the rad return was there to keep any steam in the dry return from being drawn into the rad when someone shut off the supply valve, which would create a vacuum. Remember, these systems were exceptions to the general rule that steam should not reach the dry returns.

    Not sure. I'd have to see one up close. Sometimes you just have to be there.
