The best way to determine ...

The best way to determine whether the TDS have a tendency to precipitate inside the pipeline is by calculating the so-called LANGELIER's INDEX. If this index is positive then the water has the tendency to precipitate.
In order to calculate this index you need to have a complete chemical analysis. There are sites in the web that can calculate the index automatically provided you have input the required values.

....in addition to what already told; temperature is another important factor to predict aggressive or scaling behaviour of the water, along with - as told- a complete water analysis (TH, M-alk, SO4, Cl, pH..).
TSS value (along with TDS) could help: sometimes settling of TSS is caused by weak hydraulic design and TSS settling confused with TDS deposition... but this is another story!
