Steam drum covers are located at the top of a water-tube boiler, the steam drum is where dry, pure steam collects and is drawn off while the remaining water is passed back to the heat source. Problems with the steam drum causes, at the least, inefficient heat distribution and can also result in corrosion of the steam system or boiler malfunction.

What causes water hammer? And how do you stop it?

But worse than that, you'll wind up with water hammer when the system first starts. The cold, uninsulated pipes create more condensate than they can handle. When the steam hits all that water, you get water hammer. Insulate the steam lines. The boiler's water line is priming or surging. Dirt is usually the culprit here.
