Should I Run My Pool Pump Day Or Night?

Last Updated on March 8, 2021 by

Many people prefer running their pool pumps during the night, but experts say that this practice is ineffective. Sunshine is vital for algae growth, and running your pump at night makes the conditions viable for algae to survive. It is, therefore, essential for you to chlorinate your pool during the day.

Running a noisy pool pump during the night can be annoying to your neighbors since it will distract them. However, if you still want to run your device at nighttime, you may have to buy a quiet pump or check with your city or metropolitan council regulations. 

When Can Night Time Be Ideal For Running A Pool Pump?

You may run your pool pump during the night when you want to save on electricity expenses. Chlorine distribution in your pool lasts longer in the night because the chemical does not disintegrate like during the day. Your salt chlorinator will run longer at night than during the day, which results in a lot of energy consumption.

Pumping your pool at night is also helpful when you are carrying out a chemical treatment, as this enables you to keep the levels of chlorine high. 

How To Increase Your Pool Pump’s Efficiency

If your pool pump runs for more extended periods, it may lead to higher energy bills. You can increase your pump’s efficiency by observing the following measures;

1. Manage Your Pump’s Horsepower

On average, your pool pump needs to run for 8-hours to circulate clean water regardless of intervals or the time of day. You can use a timer to help check the time, keep the pool clean, and reduce the energy bills. If, however, your pump’s horsepower is more than the size of your pool, you will need to reduce the run time. You can cut this time by 2-hours but ensure that the pool’s condition is not compromised.

You can start by reducing the pump’s run time at intervals of 30-minutes per day for better efficiency. But ensure that the water quality remains the same. Carrying out this step helps you identify the best run time for your pump that keeps your pool at its best and also cuts your budget.

2. Hand-Clean Your Pool

You can vacuum your pool or use pool cleaners to clear out debris and dirt. Doing this helps your pool pump to last longer and reduces the cost of running it. It would be best if you also emptied the pool’s filter baskets every day to prevent clogging in the drains, straining the pump, and using more energy.

3. Buy The Right Size Of A Pump.

When purchasing a pool pump, ensure that you get the correct size. A home pool requires 1HP (one horsepower) pump or smaller. If the figure is higher than one, you can consider buying a better pump. A bigger pool pump works efficiently in cleaning through filters. A modern-day pump has variable speeds that allow you to adjust the flow rate without consuming much energy.

Ensure that your pool pump does not run all the time as this might cause wear and tear, although it will keep it in pristine conditions. Running your pump for 24-hours will also lead to excessive bills, which will make it costly to maintain.

How Many Hours A Day Should Your Pool Pump Run?

To maintain your pool waters in the best condition, the pump should run for 12-hours a day. However, depending on your water’s quality and need, you can increase the length of time each day.

Some systems may require the pump to run for 24-hours a day while others can take 6-hours a day to keep the water clear. Various factors determine the number of hours a pool pump should run, including; 

1. Type And Size Of Pump And Filter

Whether in-ground or above-ground, most pools use an 8-hour turnover formula to the size of the filter and pool. Your pump size and a matching filter need to be large enough to pump and filter the pool water entirely in 8-hours.

Sometimes the pump baskets get clogged, and filters get dirty, thus slowing down the water flow. Equipment like heaters, cleaners, and chlorinators is usually added, which slows down the flow rates as they increase resistance and require more run time for the filter pump.

If the filter media is old, it may work slower and require more run time for the pump. Some pool filters are more efficient than others. For example, a DE filter will run the pump in less time than an equivalent sized cartridge or sand filter.

2. Water Treatments Or Purifiers Used

Over-treated pools need less pump circulation and filtration. If you use additional water treatments like Ozone or minerals, it can minimize the amount of chlorine required. These treatments also help in water purification by removing tiny particles, thus helping out the filter.

Using chemicals such as algaecides, enzymes, and clarifiers will also affect the length of time to run your pump. Clarifiers help filters; algaecides prevent tiny pores from enlarging, while enzymes remove filter clogging oils. We sometimes let chlorine levels slip and throw the water out of balance. You can run the filter pump longer every day to protect the water from low chlorine or stabilize the pH and alkalinity levels.

3. Debris Inside The Pool

Organic debris affects water balance, sucks up sanitizers, and clogs up filters and pumps. A pool that is in a desert environment has little or no residue. Pools in wooded areas, on the other hand, may have lots of debris or lush landscaping. Leaving your pool water stagnant for so long with trash can stain it. Running your pump will help prevent staining and bring microorganisms from twigs, bugs, and leaves into the filter.

Heavy downpour also calls for you to run the filter pump for more hours. Rainwater washes dust, oil, and pollutants into the pool. Rain will also bring stuff you don’t want into the pool, such as nitrates, microbes, and phosphates. 

If your pump is neat and tidy, the pump will run for fewer hours than the one surrounded by trees.
