The basic gist of my pump schedule is 2 hours in the morning at 2300RPM, then 10 hours at 1400, followed by another 2 hours at 2300 before shutting off until the cycle starts again the next day. During the first 2 hours at 2300, no whining. 10 hours at 1400, no whine. But some days - not every day - during the last 2 hours at 2300, I’ll get this very rhythmic whine. I hope this video captured it, been having a lot of trouble with my iPhone microphone not working lately.
My assumption is it has something to do with running all day at low RPM so maybe it doesn’t have quite enough prime or “oomph” to push back up to 2300 without a full reprime, as opposed to the first 2 hours at 2300 which has the benefit of the 5 minute prime cycle. That also might not make any sense.
I’m torn with just getting rid of the faster cycle at the end of the night and settle for a couple extra hours at the much lower setting, or changing the third cycle to a higher rpm and just run that for 30 minutes or so and see how that works. The objective here is a couple hours of good skimming early, run low all day to just generate chlorine and circulate, then a couple hours late to skim anything that didn’t find its way into the skimmer all day. But I don’t have automation so I’m at the mercy of only having three cycles I can configure in my Superflo schedule.
Any ideas on the sound and the theory behind it, and suggestions on what I should try to alleviate it? It’s so high pitched and has such a perfectly consistent rhythm, when we were out of town over Thanksgiving our neighbors called us becaus they thought it was some kind of alarm going off at our house.
