"Pumping Away" is still under copyright. While many older technical manuals enter the public domain, Holohan’s work is actively sold and supported by industry suppliers. You will find many forums (Reddit, HeatingHelp.com, The Wall) warning against illegal PDF sharing because Dan Holohan is still actively contributing to the trade.

: Dan Holohan is well-known for his expertise in hydronics and heating systems. If "Pumping Away" relates to his work in this area, it might focus on the design, installation, or troubleshooting of hydronic heating systems, emphasizing the importance of proper pumping techniques.

"Pumping Away" by Dan Holohan, often called the "little purple book," introduced the "Point of No Pressure Change" (PONPC) concept, transforming modern hydronic heating system design by encouraging installers to pump away from the expansion tank [1]. By placing the circulator on the supply side, the pump adds pressure to the system, which prevents air entrainment, eliminates noisy cavitation, and fixes cold radiators [1].
