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.
Many residential pools in the U.S. have 1.5-horsepower or 2-horsepower pumps that draw 2,000 watts or more. If youâre not paying attention, you may be running your pool pump for 24 hours a day â even though your pool might be perfectly clean with only 6 hours of pump operation per day.f you hire a pool contractor to replace an old single-speed pump with a new variable-speed pump (which comes with a controller and programmable timer), expect to pay between $1,400 and $1,800 â significantly more than the cost to install a single-speed pump ($400 to $700) or a two-speed pump ($700 to $1,000).
