Backwashing Sand and DE Share Filters, How to Operate any Pool Filter


Filtration is probably the most important factor in the blood flow system of your pool to be able to keep it clean. You can find three types of swimming pool filtration available for pool owners. Yellow sand filters, Cartridge filters and also DE Filters. It is important to realize which filter you have in your pool and how to maintain and also operate it. Each of these swimming pool area filters has its own advantages and drawbacks. With any pool separate you choose it is important to keep the right sizing in mind. Proper size refers to the pool volume along with the size of the pool pump.

Sand Filter:

Sand filters work by means of pushing water through bed furniture of sand and in laterals. Sand filters commonly have the advantage of being trusted and simple to operate. Sand filters can continually filter water without shutting off the water pump for days on end. As long as appropriate water balance is taken care of along with regular cleaning series the sand inside the filtration will be good for up to a decade. If you are having a problem trying to keep your water clean and also clear only, change the yellow sand as a last resort, other difficulties in the pool chemistry are likely the cause.

Backwashing Your Yellow sand Filter:

When the filter will become dirty pressure will build-up, and you will see this on the strain gauge. When the pressure evaluation reads approximately 5 to be able to 7 PSI above the standard operating pressure you know the filter is dirty in fact it is time to backwash. Backwashing is surely an easy process. Backing cleansing is done by first turning the particular pump OFF.

Note: Constantly turn the pump away while moving the separate out multi-port valve. As the pump is off, turn often the multi-port valve on the separate out from the ‘filter’ position into the ‘backwash’ position. Once the separate out is in the backwash position transform the pump back with. The water is then reversed over the sand by the pump. Often the dirty water gets despatched to the waste line (usually into the yard). A high junction of chlorine can wipe out grass so it is important to determine the chlorine level in the pool while backwashing.

THE ONE to 2 ppm array should be safe it keeps away from killing the grass. As the water comes out the squander line turns from dirty to clean (may consume to 3 min. ) convert the pump back off. After the pump is off move the particular multi-port valve back from your backwash position to the rinse-off position. Turn the water pump back on and let it work for about 20 seconds. And then turn the pump cool off and move it to the filter position.

Lets recap the backwashing steps:

Filtration Position-> Pump Down -> Backwash Position-> Pump On for two min. -> Pump Down -> Rinse Position-> Pump On regarding 30 Seconds -> Water pump Off -> Separate out Position

Diatomaceous earth filter:

Diatomaceous earth filters work with grids inside coated having diatomaceous earth or DOM for filtration. DE filters have the advantage of filtering into the finest particles or microns. However, they have been considered a near hassle to operate. For the right operation of a DE separate out it must be turned off for about 5 hours every day. This is to allow for the DE to drop and grow recoated when the pump pops up.

Backwashing a new DE filter:

Like yellow sand filters, they also require backwashing when the pressure rises to be able to about 6 pounds over normal operating pressure. Following backwashing, you must recoat the particular filter grids with fresh DE. This is done by giving DE through the skimmer so that it gets pumped into the filtration tank. DE is a whitened powder substance that must be obtained at the pool store. Concerning twice a year DE filtration should be taken apart as well as the grids cleaned. Most EEN filters have a multi-interface valve on them used for backwashing. Backwashing is an easy practice. Backwashing is done by first rotating the pump OFF.

Observe: Always turn the send-off while moving often the filter valve. Once the send is off, turn the multi-port valve on the filter from the ‘filter’ position to the ‘backwash’ position. Once the filter with the backwash position turn often the pump back on. This is then reversed through the grids by the pump. The witty water with old DOM gets wasted out the squander line (usually into the yard).

High concentrations of chlorine can kill grass making it important to know that the chlorine level in the pool is definitely low while backwashing. As the water comes out the spend line turns from grubby to clean (may take up to three min. ) turn typically the pump back off. Once the tube is off move the multi-port valve back from the backwash position to the rinse location. Turn the pump again on and let it run for approximately 20 seconds.

Then switch the pump back off along with moving it to the filtering position. Now is the perfect time to recharge the DE from the tank. Refer to the label within the filter for the proper regarding of DE to be additional, it should say how many lbs are required for a recharge. Change the pump back as well as go over to the pool skimmer. Add the recommended amount of pounds to the skimmer gradually.

It is best to make a slurry within a bucket and slowly bad it into the skimmer to avoid clogging. At this point, it is just a good idea to take a look at the go backline in the pool to be assured that the DE is being trapped in the filter. If you have bright powder spraying out the go back jets in the pool you then know you have a problem in anyone’s grids or the valve is focused in the wrong position.

Let us recap the backwashing measures for a DE filter:

Filtering Position-> Pump Off of -> Backwash Position-> Pump On fot three min. -> Pump Off of -> Rinse Position-> Pump On intended for 30 Seconds -> Pump motor Off -> Filtration system Position-> Pump On-> Recharge filter with HUN from skimmer
