Heart of the Pool: the Pool Pump

Of course, the real heart of your swimming pool is your family, friends, and loved ones who come around for a dip or a pool party.

Still, the pool pump lies at the heart of the pool’s mechanism and maintenance, and its function is to keep pool water well circulated and clean. The pool pump pulls water through the skimmer and main drain, filters the water, then heats it (if you have a pool heater) and returns it back to the pool, freshly filtered. Circulation of the pool water keeps chemicals mixed and removes debris, keeping it clean and free of algae – in addition to manual skimming and scrubbing.

 

How to Size Your Pool for a Pump

First, determine the gallons of water in your pool, as well as the shape. To find the average depth of the pool, add the shallow measurement with the deepest measurement, and divide by 2. There are different formulas for different shapes of swimming pools.

For rectangular swimming pools, measure the length (L), width (W), and Average Depth (A). Then, use the following formula: L x W x A x 7.5=Gallons.

For a round swimming pool, measure the diameter and determine the average depth, then use the following formula: Diameter x Diameter x A x 5.9= Gallons.

For oval swimming pools, measure the longest diameter, shortest diameter, and determine the average depth, then use the following formula: Long Diameter x Short Diameter x A x 6.7 = Gallons.

For kidney shaped swimming pools, first determine the longest and shortest width of the kidney shape. Then, use the following formula: (Longest width + shortest width) x Length x A x 3.38 = Gallons.

Once you have determined the gallons of water in the pool, you will want to divide the gallons by eight. This gives you the number of gallons you need to pump to clean all of the water in your pool in an eight-hour period. This formula will give you GPH (gallons per hour).

The final step is to convert your GPH to GPM, as most pumps specify their gallon per minute power. Divide the GPH by 60 to determine the GPM (gallon per minute).

Pool Pump Options

Pool pumps come in different options: single speed, two speed, and variable speed. Single speed pumps are the traditional option, running at a constant speed. Two speed pumps have slow and high speed controls, which allows for more efficiency. With two speed pumps, you can leave the pump on low all day, and change the speed setting when you are cleaning or heating the pool. Variable speed pumps, the latest version of a pool pump, allow for more control over the flow rate.

 

Troubleshooting Your Pool Pump

At times, if your pool pump does not function, you may troubleshoot a few items. If the pump doesn’t turn on, make sure that you have power and that all electrical connections are intact. If the pump makes a humming sound, it may be clogged with debris; in which case, clean the impeller. If the motor turns off and on periodically, it may be overheating. Check the temperature on the pump; 140 degrees Fahrenheit is normal for a pool pump. Make sure air vents are unobstructed and that the pump is using the correct voltage.
