Except for emergencies (which we will discuss momentarily), home pools typically only need to be drained once every two or three years. Commercial pools, if properly maintained and serviced, should be drained and the water replaced annually.
Pool industry experts recommend you drain your pool and refill it every five to seven years. No two pools are alike, so there is no set number at which you must drain your pool.
Don't Overlook Proper Maintenance
If you are looking to keep your family and friends safe, or own a commercial pool/spa and want your customers to stay healthy, ensure that you have your pool/spa cleaned every 2 weeks.
Ideally a pool pump should turn over the water at least once every 12 hours. Most modern pumps turn the water over in 8 hours or less.
Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up. Your pool is more vulnerable during the day, plants don't grow at night the way they do during the day–that's true of ALL plants including Algae.
One of the most significant consumers of energy in homes with swimming pools are pool pumps, which keep pools clean by circulating water through filters. Pool pumps can consume 3,000 to over 5,000 kWh per year.
Expect 24 to 46 hours of filtering to clear water. Raise pH to 7.6, increase hardness to 200 ppm and alkalinity to at least 150 ppm.
Backwashing a sand or DE filter is a simple task. Shut off the pump, set the multiport valve or slide valve handle to the backwash position, roll out the backwash hose and turn the pump on again. Backwash for 3-4 minutes or until the water runs clear, then shut the pump off and return the valve to the filter position.
Bottom Line: Yes! Robotic pool cleaners are 100% worth the investment. It'll be the best money you ever spent on your swimming pool. Any automatic swimming pool cleaner should be able to clean your pool within about three hours, depending on your pool's size.
First, if the draining is done at the wrong time or under the wrong conditions, you can actually risk damaging your pool structure and liner. All the water from your pool needs to go somewhere when it's drained, and that usually means the ground.
Main drains are not required in an inground swimming pool, however, they are strongly recommended and can be extremely useful in some circumstances. The advantages of main drains are to give you the ability to drain the water from your pool without the use of a sump pump. This is useful when replacing your pool liner.
you can tell if your main drain is working by perhaps putting a leaf on it. If it sticks, its working. In any case though, the main drain is not why your pool is having a problem. It has nothing to do with your pool turning green.
Modern concrete pools can usually stand being drained for as long as needed, but there'll still be a risk of popping if the ground water level is high. Fibreglass pools are less resilient. The floor may come loose and float to the top when refilled, even after a short period.
How long can you leave a pool empty? Well, the minimum amount of time possible in order to minimize the risk of serious damage. Most issues that require a pool drain will take at least a day or two to resolve, but it's recommended to not let it sit empty for any extended period of time.
A 10,000 gallon pool will take about 14 hours to drain, the maximum rate recommended by the City of Phoenix. It will take twice as long to drain if the pool size is doubled or cut in half.
Brushing and Vacuuming
Keep the pool clean by regular brushing of the walls and vacuuming of the floor. This is part of a good commercial swimming pool maintenance routine. Brushing the walls keeps the walls clean and prevents algae from growing on them. Vacuum the pool as part of daily maintenance.
Low flow = poor circulation which will lead to algae in the pool. Bottom line, the filter must be backwashed on a regular basis to ensure that your pool water is clear. "When do we need to backwash?" - It is recommended to backwash your filter once every 4-6 weeks of regular use.
Rinse runs water in the same direction that normal filtering does. Backwash runs it through the sand in the opposite direction. Rinse is to clear any dirt out of the clean side of the sand before you start sending it back to the pool.
If used properly, free chlorine* can kill most germs within a few minutes. CDC recommends pH 7.2–7.8 and a free chlorine concentration of at least 1 ppm in pools and at least 3 ppm in hot tubs/spas.
The basic task of a pool's life guard is to save people from drowning in the pool in order to prevent unfortunate deaths due to drowning. And every public swimming pool should have a lifeguard.
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.
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. A proactive, productive and energy-saving maintenance activity is to remove the debris floating on the pool surface with a hand-held skimmer.
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.
