7 Common Dead Legs

Dead legs in building water systems can cause severe problems, including persistent positive Legionella test results and an increased incidence of Legionnaires’ disease. Dead legs are sections of water system piping with low or no flow due to system design and/or operation. A basic understanding of dead legs, how to recognize them, and how to manage the problems they cause can help building owners reduce the risks associated with Legionella and other pathogens in their water systems.  While the ideal solution is to remove the dead leg, the more realistic methods are a combination of design, operational, and maintenance strategies. Here are 7 common types of dead legs and some practical, effective methods to manage them.

How Sodium-Cycle Water Softeners Work

Hard water can cause a variety of serious problems. Water containing dissolved calcium and magnesium ions can lead to the buildup of limescale, which can impair and damage industrial equipment such as heat exchangers. Furthermore, the presence of these ions significantly reduces the lathering ability and overall effectiveness of soaps, making for subpar wash water.  Water softening is used to combat hard water.

How Cooling Tower Systems Work

Cooling towers are recirculating water systems used to remove heat from building air conditioning equipment and industrial processes. They require specialized maintenance to ensure safe, efficient, and reliable operation, including an effective water treatment program.  By understanding how cooling tower systems function, facility owners and operators can operate and maintain their systems more effectively.

Is Your Closed Loop System Losing Water?

Closed heating and cooling water systems typically require little makeup water and minimal chemical additions following the initial system charge. However, when leaks occur, it can be costly and difficult to maintain the treatment levels necessary for corrosion and deposit control.
