Trane vapor system

Dave_23Dave_23 Member Posts: 190
I have a residential two-pipe Trane steam system fed from a WM EC-35. I finally got around to installing an oz/in gauge on my system. Although the house heats evenly and just fine, the system only makes about 1.5 oz of pressure at full steam. My vaporstat is set to cut out at 4 oz of pressure (system never trips on pressure, only temp). Is 1.5 oz full pressure too low, indicative of a leak or is it ideal (low pressure being better)? Thoughts and thanks?

    if it heats all the rads at 1.5 ounces, that great. Not indicative of a leak, especially if you are not adding much water to the boiler.

    Lol, I think so.

    :) Not bragging LOL, just a homeowner with a rudimentary knowledge of steam systems. The water level never drops and the boiler only feeds every third year or so. I have to check the feeder every so often to make sure it's still working. Btw, I have an EG-35, not an EC. I heard low pressure is best, but wasn't sure. Most of what I've learned about steam is from The Wall.

    It soounds like that system is working perfectly! Maintain it properly and if you decide to "Tinker" with it, put it back the way it is!
