What do you guys use to check the hardness of the water in the boiler system. I do have a PCSTestr 35 meter and that will show pH, conductivity ,TDS ,and temperature. I think that was all. But I'm wondering what's the best way to determine the hardness of the water?
Also, from the reading that I've done, it seems a fairly complicated process to determine what additives would need to be used to Rectify say high TDS. I just pulled a water sample and it shows a TDS of 320 and the conductivity of about 450.. I did call the owner and found out that it's probably fed with softened water and definitely has had leaks, so water has been added. This system probably holds 2- 300 gallons maybe more and having read a number of threads on this site about it I see where @Hotrod
says that it's a fairly complicated business knowing how to treat the water. So I guess one of my questions would be do you just add a Rhomar or Sentinel 100 in there after Flushing the system, or is it a good idea to bring in a water treatment company and get a relationship with them?
I have read the caleffi hydronix 18 water treatment manual. One of our Engineers is starting to use some of those products so I have hopes that we will be progressing! LOL
