Last month I discussed the niche business of troubleshooting and the pertinent things to do in preparation of the data collection, data analysis, and eventually the potential solution(s) plan. This month, I’m going to continue with this topic, focusing on water-side problem solving.
I mentioned some of the skills necessary to problem-solve last month, but to be more specific to troubleshooting a water system, here are a couple of problem-solving basics you don’t want to skip over at the very start of the data collection phase:
- Make sure the pump impeller diameter matches the impeller size on the printed pump curve. Over the years, I’d estimate that 98% of the time, when verifying the pump impeller, the impeller size on the manufacturer’s pump curve matched the actual impeller. Still, 2% of the time, while troubleshooting a problematic water system, I have found the actual pump impeller did not match the published pump curve. To verify the impeller size, perform the following steps:
