Similar to the difference in diligence (or attitude) in running drain tests. You're SUPPOSED to (good practice) hang the drain test results at the valve for comparison, and advise when results are different. How many penny loafer inspectors run the drain test, write down the results, and then go to the next one without comparing results? Maybe I should say running shoe inspectors for the amount of time and attn paid to the RESULTS of the ITM, no sense in running drain test if you don't compare the results.

If the pressure at rated flow is less than 95% of the acceptance test or nameplate data, an investigation into cause is warranted. I have clients who ask me to review the pump test results. Sometimes the contractor offers an opinion on performance and sometimes not. 25 does not explicitly require the contractor to do the analysis. If you run the test and see a degradation in performance of 5% or more, it would be prudent to notify the owner that there may be maintenance issues that need investigation.

I've been using a spread sheet to compare the current test with the original acceptance test (rarely available) and with previous tests. I'm finding what may be concerns and I would like to provide a code reference to the owner. Thank you!
