I have an older Whisperflo 2 speed pump on my "new to me" pool. It currently runs on low continuously (24/7/365!!!) and switches to high on an Intermatic timer for whatever time period I set. Currently about a 2 hours a day. This seems incredibly inefficient and wasteful. My rough calculations say that if the pump ran on low for 18 hours a day I'd still get 4 turnovers per day. Some might say that would still be excessive.
Also, the SWCG is wired so that it is only powered when the pump is on high. I expect that the flow rate on low will be more than sufficient trip the SWCG flow switch regardless of how much debris is in the filter. Low seems to be in the range of 40 gallons per minute. I don't see a reason to run the pump on high every day. I also don't see a reason to run the pump on low 24 hours a day.
The pool heater currently runs just fine on low flow and shuts down automatically when there is no flow. I don't expect any issues there.
The thought is to rewire the unit to operate on low off the Intermatic timer and wire the SWCG so it operates when the pump is on low as well. I'll then back the SWCG production percentage way off. Before I get too involved with the wiring I will first rewire the SWCG to verify it will function properly on the low pump setting. High will then be on a manually timed knob for vacuuming, adding chemicals, etc.
How is yours wired and when does it operate? Thoughts, ideas, and opinions are appreciated.
