Open the air bleeder assembly on your filter and turn pump on. Watch the pressure gauge for spikes. After the hose fills with water, backwash your sand filter for 2 - 3 minutes, or until water runs clear.
Turn the pump back on and backwash until for 2 minutes or until the water runs clear (you can check this in the sight glass on the side of the filter). Turn the pump off. Select the RINSE setting on the filter valve. Turn the pump back on and rinse for 1-2 minutes.
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.
Essential Backwashing Tips
Stop it immediately after it clears. -Top up the sand in your filter after a backwash since the process will wash out a lot of it. Run the rinse setting while you top up the sand to ensure it doesn't go back to the pool.
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.
Turn the lever to RINSE, start the pump and rinse for about 15-30 seconds. Stop the pump and turn the lever to FILTER. This is the normal operating position. Close the drain outlet valve and start the pump.
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.
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.
It is not recommended to drain a swimming pool through the backwash valve. While sucking from the main drain and putting the water down the backwash line will work in some scenarios it puts your pool pump at risk of losing prime and running dry.
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.
In most cases, the cleaning time is set in the early morning when everyone is asleep. Every 4 to 7 days, the backwashing system gets activated and completes the cleaning process by itself. You do not need to manage the backwashing system personally.
In general, you shouldn't be losing sand from your sand filter. Nor should any sand be coming out during backwashing, rinsing or filtering. If sand is coming out, something is wrong. You shouldn't need to be topping up the sand in the filter either.
You should backwash your DE pool filter about once a month during pool season. In addition to the regular schedule, you'll want to perform additional backwashing if: You've been running your pool filter for 48 hours straight. This can cause a pressure build-up, even if the filter grids look clean.
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.
That said, many pool owners backwash weekly as part of their summer maintenance routine, often after they vacuum to collect the remaining particles that are often stirred up.
The process of backwashing dislodges trapped debris and contaminants, flushing them out through your value's waste line or a hose that is connected to the pool pump. When the filter media is clean, the pressure gauge is lower and water can easily flow in and out of the system.
For inground pools with a sand or DE filter, the easiest way to quickly lower the water level is to place the multiport valve into the waste position and roll out the backwash hose. If instead, you have a slide (push-valve), backwash the filter to lower the water level.
Usually the wastewater generated from backwashing is discharged to the sewerage system in accordance with a trade waste agreement with the local sewerage authority.
Swimming pool water contains chemicals, especially chlorine, that can harm your trees and landscape plants when water drains and floods the area. Too much chlorine can damage tree leaves and other delicate tissues.
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.
If you do have this option, it is highly recommended that whenever you have algae, you will need to vacuum to waste. This option allows you to vacuum the algae up and send it out through the backwash line, avoiding getting algae into your filter sand.
After backwashing, new DE must be added to the filter. Add the entire amount of DE the filter recommends. If you see DE returning to the pool, vacuum it to waste, after it settles. The next time you backwash and recoat, decrease the amount by 1 pound.
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.
