How much are you filtering your pool water?
You could know if you had a flow meter. Installing a FLOWREAD Flow Meter on any current pool system provides an accurate reading of the flow rate - allowing the correct adjustment of a variable speed pump's output relative to the size of the pool.
The benefits of this include:
Proper filtration for your pool water, reducing dependency on chemicals that can irritate swimmers
Avoiding damage to your filter (flow rate too high)
Preventing damage to your heater (flow rate too low)
Reducing energy costs

U.S. Department of Energy Mandate

The U.S. Department of Energy has set minimum efficiency standards for selling a pool pump in the United States. Right now, that standard is only satisfied by variable-speed pumps. With a variable-speed pump, a pool owner can circulate their water at lower flow rates for longer without added energy consumption. The fact is that variable-speed pumps are significantly more energy-efficient than single-speed pumps. However, it is up to the pool owner to save energy by dialing in their variable speed pump to the correct output, and the way to do that is by knowing the flow rate in the pool's system. A flow meter is necessary to achieve the correct flow rate.
