: when testing the conductivity of the feed water tank. i'm getting higher than recommended levels.what could be the cause.
At what point are you injecting your chemicals for water treatment? If the check valve in the boiler feed/pump line leaks back to the feedwater tank, that might explain the higher levels of solids or conductivity. Also, in some areas the fresh water make-up is higher in mineral content thus causing high readings. Have you tested fresh water make-up and condensate return samples? There is another possibility...contaminated condensate due to a leaking coil or jacketed vessel.
