For example, a minimum wage of $10 per hour will have no effect for workers whose marginal productivity in a given line of work is greater than $10 per hour. The legal supply and demand remains unchanged for such labor.
One way to keep control of the time you run the swimming pool pump is to run it several times a day for short periods of time. If you want to activate the pump once a day, start with six hours, but never go lower than five hours, especially in the summer. If your pool is in constant use, you may need to run the pump for up to eight hours per day, frequently checking the water clarity and chemical balance.
Pump Timing. A pool pump should run for as long as necessary to circulate all of the water through the pump and filter system. This turnover rate varies based on pool size and the pump. Pumps can typically circulate all of the water within a 6 to 8 hour period; some pools require pumping for up to 12 hours.his turnover rate varies based on pool size and the pump.
