Yes, pool pumps use a significant amount of electricity, making them one of the biggest energy consumers in a home. A pool pump can use up to three times as much electricity as a refrigerator. Typically, a residential pool pump consumes about 1 kilowatt-hour (kWh) for every hour it runs. Because pumps often need to run for about eight hours a day to properly filter the water, this can add up to an annual consumption of 3,000 to 5,000 kWh, which can cost between $480 and $800 per year based on average electricity rates.

The amount of electricity your pump uses depends on its size, energy efficiency, and daily run time. To lower your energy consumption, you can choose an energy-efficient or variable-speed pump, ensure it is correctly sized for your pool, and run it only for the minimum time required to keep the water clean.

It is a good idea to brush a pool before shocking. Brushing the sides and floor loosen up anything that is growing on the surface, such as algae. It is then easier for the pool shock to kill the contaminants because more of it will come in contact with the chemicals.

Liquid chlorine is better for shock treatments or instances where you need to raise your chlorine levels quickly. Tablets are better for regular maintenance. Tablets take more time to dissolve but require less effort. You don’t need to measure out volume, and you can set them in a floater and let that do the work.

Losing some water from splashing and evaporation is normal. However, if you notice a rapid drop in the water level or are adding water more frequently than usual, you might have a leak. Other common signs of a pool leak include:

• Unexplained soft, mushy, or wet spots in the yard.

• Cracks in the pool's structure or falling tiles.

• Higher-than-normal water bills.

• Persistent algae growth or water discoloration.

• Standing water near the pump, pipes, or other pool equipment.
