1) Why not use a drop header?
2) There is a McDonnell low water cut off that mounts right in the fitting; is it not available?
I do have a drop down header. I put in a substantial 4 inch drop down header that is working flawlessly.
Two reasons I did not use the 2.5inch port that Axeman supplies for my low water cut off: First, the low water cut off intended for that type port is the McDonnell model #69. It is an older design that does not have the provision of a valve attached so that one can do a weekly blow down. It is recommended that you remove it from the boiler annually for cleaning. I much prefer the model 67 that attaches to the sight glass plumbing and has the attached valve with it so that I can blow it down weekly and test it when I do so.
Secondly, I can now use the available port as a skim tap port, which you see being used in the above videos.
