The rule of thumb is generally 8 hours, although it could be anywhere from 6-12 hours, depending on your pool's size. Each pool is unique, so to keep your pool pump efficient and effective, you need to figure out exactly what your pool's turnover rate is.
It's best to run your pool pump during the day
Not only does sunlight give fuel for algae to grow, it also destroys your pool chlorine and this is why you should always run your pool during the day!
Trust us when we say it's important to keep your water pump continuously running throughout the pool season. For hotels and other types of public pool spaces, it's actually a law to keep a pump running nonstop; but for homeowners who are concerned about saving energy, resources and money, have no fear.
A Rule of Thumb
Generally running your pool pump for 12-hours a day is a good option. This is based on the assumption that your average pool pump has a turnover rate of about 8 to 12-hours. That means that the total volume of your pool water will filter through your system 2 to 3 times per 24-hour period.
The size of your pool, the efficiency of your pump and filter, and how dirty your pool is are just some of the factors you need to consider. Nevertheless, most pool cleaning professionals would advise against running a pool pump for more than 8 hours a day.
It may be cheaper to run the pump at night, but honestly you should run it 1 hour a day per 10 degrees of temperature at least, and it should be during the day. Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up.
Every pool must turn over at least once a day, so most pool pumps should run approximately 8 hours a day. But here's the thing: you don't have to run your pool pump consecutively. You can choose to run it for three hours in the morning before you leave for work and another 5 hours in the evening.
You cannot run your pool pump every other day because the standing water can pose a health risk as it can quickly accumulate bacteria and fungi. It is crucial to run the pump every day for 8 hours (in one or multiple sessions), so the entirety of the pool's contents run through the filter once.
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.
Run your filter pump for at least 12 hours a day, every day. This will make sure all the water in your pool circulates at least once. In an ideal world of bottomless money vaults, you could run your pool pump 24 hours a day, but 12 hours is a good compromise.
Should I run my pump while it's raining? Zagers says yes! We recommend that our customers run their pumps rain or shine UNLESS we have an electrical storm. In that case, lightning could strike an outside circuit, which could damage your pump and other equipment.
Without Chemicals
If a parent chooses not to use chemicals in the kiddie pool, the water must be drained after the children are done using it. This should occur within 24 hours. That means the parents must go through the hassle of filling the pool with fresh water each day.
You should run your pool pump and filter at least once a day to ensure you get proper filtration. Whether you have an inground pool, permanent above ground pool or portable above ground pool like an Intex, Summer Waves or Best Way pool, you'll want to run your pump daily and on average for 8 hours.
Aim to maintain a chlorine level of 3 to 5mg/l at all times. How frequently you add more chlorine will depend on your usage and bathing habits. It could be daily, every two to three days or weekly. For 1mg/l, add 2g per 1000 litres.
The Bottom Line about Pools and Chlorine
As mentioned above, you could probably swim in a pool without chlorine without any major health issues. However, long-term use of a pool lacking chlorinated H2O could make you sick or, at the very least, contribute to rashes and other types of skin irritation.
Most floating chlorinators can hold anywhere from two to eight weeks worth of chlorine, depending on conditions such as the season and your pool's size. An automatic feeder works in a similar way, allowing it to mix with the pool water slowly and deliberately. This type generally comes in a large bucket.
Chemicals that you add to your pool while the water is circulating don't need to be recirculated; they will stay mixed even if you don't pump the water continually. Although it's generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time.
Answer: It should not matter much. It could help to filter debris and contaminants the rain washes into the pool. However, lightning can be a concern with the filter running.
Even if you have your pool covered, some debris may still get in it during the winter. For this reason, you should consider running your pump on occasion whenever the outdoor temperature is between 35 and 65 degrees. Around four to six hours should be sufficient to remove debris and help promote good circulation.
Heat transfer efficiency is higher with higher flow rates. However, you have to look at total efficiency and cost. It may be worth the extra heat loss to run the pump at lower speeds.
For energy efficiency best time to run the pool's filtration system is during off-peak hours when the electricity demand is lower. This time is typically between 8 p.m. - 10 a.m. Also, to warm the pool you can run it during the day, to cool it at night.
Maintenance is critical when it comes to the quality of your pool water. Well maintained pool water can last up to 5, maybe even seven years before you need to replace it. This means weekly cleaning, functional filters, and checking ph levels every day. Usage is a huge determining factor.
It takes a lot of chemicals to make pool water safe for swimming. Untreated water can accumulate harmful Escherichia coli and Salmonella bacteria and protozoans such as Cryptosporidium parvum and Giardia lamblia.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
If your pool pump manufacturer has declared your pump is rain safe, you can leave it on in rainfall. Nevertheless, during a thunderstorm, it is highly recommended that you switch off and unplug your pool pump to prevent any costly and irreversible damages to your pool equipment.
