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.
Why will the sand last less if I backwash too often? Backwashing a filter too frequently will keep the sand so free of dirt buildup that it will not have the ability to remove the smaller particles of dirt and they will simply pass through sometimes causing cloudiness in water.
After the hose fills with water, backwash your sand filter for 2 - 3 minutes, or until water runs clear.
Set the filter valve handle to the RINSE position and ensure the handle locks in place. Turn on the pump and run the rinse process for 30-60 seconds or until the water in the sight glass is clear.
Yes, we recommend backwashing after you vacuum your pool. This allows the filter to shoot out any dirt / debris you have vacuumed up. Don't forget to set your filter to “rinse” for 30 seconds after backwashing!
Whenever the filter fills up with the dirt/debris it reduces the flow of water to your pool. 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.
To begin vacuuming your pool:
This option allows you to vacuum the algae up and send it out through the backwash line, avoiding getting algae into your filter sand. However, you will need to vacuum quickly, as water will be exiting your pool quickly.
The 'Rinse' setting should be used after backwashing and again run just for a minute or two. On this setting the water is flowing through the filter in the normal direction but once again is being sent to the waste pipe rather than being returned to the pool.
Backwashing reverses the flow of water, lifts up and flushes the sand, and then expels the dirty water via a waste line into the ground or drain. In order to prevent residual blow back into the pool, once you've finished backwashing it's highly advisable to rinse the filter.
Your sand filter is designed to operate effectively with a certain level of sand in it. When the sand level in the filter housing or sand tank is too high, then you may notice sand coming out of the backwash lines when you backwash or use the rinse function.
Add diatomaceous earth (DE) to your pool skimmer, stick to around a scoop or two – no more than the size of a 1lb coffee cup. The moment you do this, go to the pool jets to see if it is returning DE into the pool, or if the water suddenly looks cloudy. If it is, you likely have an issue with your filter.
* Can i discharge the backwash water onto my lawn, will it harm the grass / plants? The DE doesn't harm the grass or plants, excessive chlorine or saltwater may.
Backwash only as needed. Brush the pool vigorously, several times after shocking the pool. Do not use a solar blanket until chlorine and pH level are normal. If chlorine level drops to zero within 24 hours, Repeat the shock treatment.
As a general rule, you should be backwashing your pool about once a week or in conjugation with your scheduled maintenance. Another industry standard is to backwash when your filter's pressure gauge reads 8-10 PSI (pounds per square inch) over the starting level or “clean” pressure.
Typically, you should backwash a pool if the pressure gauge on your filter is at 8-10PSI at the starting level. So, to answer the question of how often should you backwash your pool, check your PSI. If the filter runs well at 16PSI and then goes up to 25PSI, your pool needs a backwash.
After a backwash, to get the amount of DE powder, simply take the recommended amount of DE powder for a new filter and multiply it by 0.8, or 80%.
What Is Backwashing? 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.
Yes, you save water with FilterBalls with the backwashing. The filter cleaning (backwashing) process with sand, glass, and zeo-sand require frequent cycles to remove dirt from the media and restore the media's filtering capacity.
The filtrations system can operate at low water flow with typical motor speeds around 1000 RPM or less depending on the size of your pool and how long you want to run the pump. Suction cleaners typically run at around 2200-2400 RPM.
Of the three main types of pool filters, a cartridge filter uses the least amount of water.
Turn off the pool pump. Turn the valve to the backwash position. Turn on the backwash valve and let water run through the backwash hose for 2 to 3 minutes, or until the water coming out runs clear. This will rinse out any organic matter in the filter.
Cleaners aren't meant to stay in the pool 24/7. This is true for all cleaners. Pressure side cleaners run on a schedule every day so why take it out? Leaving the cleaner in the pool 24/7 increases its exposure to corrosive chemicals in the water, such as chlorine or shock.
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.
Do not operate your filter pump without having the D.E. powder coating the grids, or you will see the filter pressure rise very quickly, and if left in this manner the grids can collapse or the fabric can become clogged or damaged. As the pressure gauge on a D.E. filter increases, flow rate decreases.
