Asked by: Nicole Smith
The backwashing process reverses the flow of water to flush out contaminants from a swimming pool filter. It should be carried out until water runs clear through the waste line.
How often do you need to backwash a pool?
once every 4-6 weeks
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.
What is the reason to backwash the pool?

Does backwashing remove water from pool?
Well, as the name suggests, backwashing involves reversing the flow of water through your filter media, be it Zeoplus, sand, glass pearls or diatomaceous earth (DE). This dislodges dirt and debris that may have become trapped, and flushes it out through your multiport valve waste line.
How long do you backwash a pool?
After the hose fills with water, backwash your sand filter for 2 – 3 minutes, or until water runs clear. Shut off the pump motor and push the T-handle back down into locked position. Turn your pump back on and note the lower pressure.
Where does the water go when you backwash a pool?
Simply put, when you backwash your pool filter, you reverse the direction of the water flow, and water moves back through the pool filter and out the waste or drain port. Just make sure you’re disposing of it properly—and we’ll get to that soon. All in good time, my friend.
What is the difference between backwash and rinse?
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.
Does backwashing remove algae?
Use a pool brush to vigorously scrub the surfaces where the algae has grown. Use a vacuum or backwash the pool to remove the dead algae.
Should I backwash pool before shocking?
Lower the pH before shocking, 7.2 – 7.4 is best for shock efficacy. Dilute pool shock in a bucket of water for vinyl liner pools. Run the filter 24/7 until water is clear. Backwash only as needed.
Why does sand come out when I backwash?
Your pump may be too large or the sand level too high in the filter. When the filter is backwashing the water flow can cause the sand to rise high enough and overflow into the standpipe, which will allow the sand back into the pool.
Can you backwash a pool too much?
Can You Backwash Too Much? If you backwash your pool too much i.e. time duration and/or close frequency then yes you can cause a lot of problems. Some problems that can arise from backwashing your sand pool filter too much are: Loss of water – 500+ litres of water can be lost in each backwashing cycle.
What is the difference between backwash and waste on a pool filter?
Drain/Waste: Opting the drain or waste setting will remove pool water without forcing it through the filter. Backwash: This clears out any debris, dirt and other contaminants that may have accumulated on the filter. Closed: if you choose this setting, then the flow of water to the pool and filter will be stopped.
How often should I backwash my water filter?
once every 1-2 weeks
Simply put, backwash filters will need to backwash once there is noticeable pressure loss through the filter – typically once every 1-2 weeks.
How do I backwash and rinse my pool?
Setting. After back washing the sand is loose and needs to be reset. Also any dirty water from the back washing has to be rinsed out of the filter to waste to prevent it from returning to the pool.
How do you backwash an above ground pool?
You do need the pump to be turned off so we're gonna go ahead and turn our pump off here. And you're gonna come over to this valve that should be set on filter.
How long do backwash filters last?
Typically, a backwash filter cycle will last for 6 to 15 minutes in a residential application. First, water is forced upwards through the filter bed, causing the media to expand, and as it does, the water carries the particles in suspension to the drain.
How do you backwash a sand filter?
How to Backwash a Pool Sand Filter
- Turn off the pool pump.
- Set the filter valve handle to the ‘Backwash’ position and ensure the handle locks in place.
- Turn the pump on and backwash for 2 minutes or until the water in the sight glass (located on the filter) is running clear.
- Turn off the pump.
How often should you backwash iron filter?
or twice a week
Iron filters take this clear iron and transform it to rust or ferric iron in the process known as oxidation in an aerobic environment. These trapped particles are periodically and automatically backwashed out with the flush or backwash of the filter, usually once or twice a week.
Do you need to backwash carbon filter?
Because the GAC carbon is reused over and over for typically 4-5 years. Sediments and rust are periodically flushed down your drain during the “backwash” mode. Set the timer to backwash the carbon every 2-3 days. Backwash every 1-2 days if you have sediments but no sediment prefiltration and you use a lot of water.
How often do you backwash a carbon filter?
Catalytic carbon backwash filters typically need media changed every 4-6 years. A water softener resin bed normally lasts 5 to 10 years.
What is carbon backwash?
A. The Backwashing Carbon Filter is a large filter canister filled with activated carbon media. Activated carbon removes chlorine in a chemical reaction that oxidizes the carbon surface. Chlorine tastes and odors are removed. Sediment down to 30 microns in size is also removed by mechanical filtration.
Do carbon filters filter sediment?
What is Carbon Filtration? Carbon filters remove sediment; plus, chlorine, volatile organic compounds (VOCs), odors and unpleasant tastes from water. They contain activated carbon, which strengthens the bond as water passes through it.
What goes first sediment or carbon filter?
The water should first go through a sediment water filter to reduce sand, dirt, rust, and other sediment. You want to have the water go through a sediment filter first so it does not clog up the carbon filter, which is more expensive. The sediment filter will prolong and protect the carbon filter.
How often should you change sediment filter?
every six months to one year
You should change your sediment filter every six months to one year. However, the best way to know when you’re due for a filter change is to observe your water pressure. When your pressure begins to drop, you need to change the filter.
Does a charcoal filter remove chlorine?
Activated Carbon filters are excellent at removing chlorine and related poor taste and odor. High quality activated carbon filters can remove 95% or more of the free chlorine.
What does gravel do in a water filter?
Filter Gravel is an extremely effective filter media because of its ability to hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering.
What does cotton do in a water filter?
The cotton ball layer helps to keep the other layers of your filter from falling out into your water. The sand layer acts as a coarse filter for large muddy particles and to keep the activated charcoal or clay particles from getting into the cleaned water.
