the clanking is back

At the beginning of the winter, we were chasing the dragon and trying to fix all of the clanking issues from the steam heat in our home. We got the system down to the rare water hammer clank, which has been great.

Now that the weather is warmer, it appears that the clanking in one of the radiators has come back. Is this common?

    Steam is probably hitting cooler water since the boiler runs a heating cycle less frequently. Find the area where water is pooling, maybe in that radiator or a horizontal pipe that feeds it and correct the pitch. If pitch is good, check and make sure the system pressure is below 2 PSI. High pressure may prevent condensate from getting out of the radiator and back to the boiler.
