Location of steam radiator trap test station

I'm planning the installation of a radiator steam trap test station. It seems like the simplest location for the test station is the piping for the low water cut-off units. I could remove one of the plugs from the piping (see picture) and install a test station with the appropriate valves & safety precautions.

Would that be OK? Or is there a better location I should shoot for?

    That's a good idea. I don't see any reason that would be a bad place to locate it.

    Could the condensate from the trap run down into the cross and never cool the trap to open?

    I wonder if you should come out of the horizontal part of the cross with a valve and then 90 down and then out to the horizontal for the trap.
    That would let some condensate collect to cool the trap and open for dumping and then close again. Just a WAG.

    is there a place you can get dryer steam from?

    23 of my radiators have a Hoffman 17C trap, and 6 have a Sterling 750A. Both are elbow shaped with the exit pointing down.
    So I was going to make pipe T, with one each of these traps at each end of the horizontal part of the T (exit pointing down), preceded by a valve. The steam would enter the middle of the T and stop at the valves. I could put questionable inserts in a trap, open the corresponding valve, and watch for spit and steam coming out from under the trap.
    So the vertical part of the T would be very short and I didn't think there'd be much condensate in it.

    But the more I think about, the less I'm excited about doing this on top of the boiler. It may be technically OK, but do I want spit and steam coming out over my instruments? And when I torque the trap lids off and on, how will I avoid torquing the middle of the T as well?

    is there a place you can get dryer steam from?
    I have an opening in one of the main loops where a feed used to go to the garage before the garage radiator was removed. But it is along the basement ceiling, so the pipe to the T of the test station would have to go down to an inverted T. I could mount the test station securely to the wall (good) and put a valve at the high point by the main to prevent water from filling the pipe that goes down to the T. But I don't think this steam will be dryer.
    My other options are the typical openings on the side of the boiler for gauges and instruments. I could pipe from there to a wall in the boiler room and fasten my T there.

    Any further feedback is appreciated.

    The best location is 91 Pacella Park Dr Randolph, MA

    Happy to test them for you if you decide you don't want to bother with a setup.
