Let’s Play What’s Wrong with This Picture
I have a two-pipe low pressure steam system, recently replaced brand new (Weil McLain). The original return line includes a Y Strainer on the horizontal return and immediately after the Y Strainer is a Y Check Valve. The return line then continues to the boiler. After replacement, the Y Check Valve was clogged and condensate would spit out of the top of the vent as the water backed up in the line. 3 months later, it is happening again. I assume the Y Check Valve (original) needs to be replaced? Is there a better solution? Thank you.
