I want the 2nd pse802-24 to shut the burner only if the 2nd low water cutoff "reports low water". Is that possible and how?

    It's possible -- but it's not safe. The low water cutoff is there to ... shut the burner off on low water. Period.

    If you have two low water cutoffs, it's to provide a backup in case one of them malfunctions -- which, on occasion, they do. The second (lower) cutoff should be a manual reset, so you have to go to the boiler and find out what happened before you turn it back on.

    Figuring out how to disable one of the low water cutoffs isn't at all difficult. Since, however, it is -- as I say -- incredibly dangerous, I'll leave it to you to risk your own house and life. Not going there.

    Why?

    Is this the job?

    A lot of folks on this site would love to know how ProPress fittings work on steam. I would not have used copper, but keep us in the loop over the next few years. You will have a captive audience.

    My second boss found out the hard way that PVC does not work on steam boilers. That was over 40 years ago when the new plastic stuff just came out

    Now if anyone wants to experiment with Mega Press, That would also be interesting.
