Water quality specifications

I've got this question emailed to a boiler manufacturer but am still searching out the answer. I have a job where repeated pump failures and other issues point to either a water leak or frequent pressure releases due to either a compression tank problem or feed valve issue. This job is across the state and the dealer doesn't agree with my thoughts. Before I drive the distance to inspect the job, I want to arrange for a laboratory to test both the fresh water and and a sample of the boiler water. I spoke with the lab and they need to know what they are to test for.

Does anyone have such specification that either boiler makers or circulator pump makers might have?

    maybe this might help you...

    Steve... maybe will help you, I got this info from a Rohmar tech a few years ago.....

    pH - value dependent on boiler/system type


    alkalinity P-M or T

    Chlorides (50ppm max)

    total hardness as CaCo3 (6-7 gr or 100ppm)


    azole (13-15 ppm)

    nitrate (24-28 ppm).
