What should a hydronic pipe system be cleaned with after installation?

A hydronic pipe system should be cleaned with trisodium phosphate (TSP) after installation because it is effective in removing debris, oils, and other contaminants that could impede the system's performance. TSP is a powerful alkaline cleaner that can dissolve and suspend dirt and grime, ensuring that the inside of the pipes is free from any potential blockages or reduced efficiency. This is particularly important for hydronic systems, as any buildup could lead to poor heat transfer or even damage to the components over time.

Using other cleaning substances may not be suitable for this purpose. For example, soap and water may not effectively remove all residues that can contribute to problems within the system. An acid solution could be too harsh and potentially damage the piping if not used carefully, and a bleach solution may lead to corrosion or other undesirable effects within the system materials. Therefore, trisodium phosphate is the preferred choice for cleaning hydronic systems after installation, ensuring they operate efficiently and effectively from the start.
