: My question is, after $232.00, are these thermocouples oem for Weil Maclain, or can I get them at a local home depot?
+++ You can get them at your local plumbing-heating supplier or home center.
Are there milli-volt ratings I need to look out for?
No, they are either thermocouples or not.
: My final question is after the tech fired up the boiler, it was getting too much water pressure, and he did something to an adjustment screw on top of my B&G reducing valve . Why would he have to do this if its factory set at 12 lbs?
He wouldn't. Water expands when trapped in a sealed system, so the water pressure would go up by heating it. That is why there is an expansion tank.
