WATER CHEMISTRY REQUIREMENTS AFTER PRE-TREATMENT New Copper Pipe Installation When new copper pipe is installed must wait 60 days prior to install. Because the new copper pipe has the potential of leaching copper into the water until it has a chance to build up a patina. The time required for this varies greatly from a few days to 60 days depending on water chemistry and how much damage was done to the plumbing system by the excessive use of corrosive flux in the soldering process. Temperature The seed crystals that are produced by the media will continue to grow or partially re-dissolve depending on changes of Langelier Saturation Index of the water. Temperature is one of five parameters that are factors in LSI. Hardness: 0 - 75 GPG Temperature: 36 – 122˚F (2 - 50˚C) Pressure: 40-100 psi Chlorine: < 3.0 ppm Iron: 0.0 ppm Sulphur: 0.0 ppm Manganese: 0.0 ppm Phosphate: 0.0 ppm
