How do I Clean a Pool Filter

A clean pool filter is crucial for maintaining bather comfort and extending the life of pool equipment.
Instructions; How do I Clean a Pool Filter:


Step 1: Clean a crushed sand filter by back flushing water through the system on a regular basis (about once a month). Your system’s pump station will come with instructions on how to reverse the water flow to clean the debris from the filter.


STEP 2: Replace the sand in a crushed sand filter completely every three to five years, depending on the amount of use the pool gets during each season and the kinds of large airborne contaminants your filter encounters.


STEP 3: Replace the diatomaceous earth in a diatomaceous earth filter two or three times a year to make certain the grid-structured system filter is working at maximum efficiency.


STEP 4: Rinse a modern enhanced cartridge filter in the sink when the pressure gauge on your pump begins to show a rise in pressure of 10 or more lbs., and then place it back into the unit.


STEP 5: Replace the cartridge of these modern enhanced filters every two to three years. You will know its time to replace the filter when the pressure doesn’t go back down to the normal range; it has become clogged with hard deposits that cannot be rinsed out.

Tips & Warnings; How do I Clean a Pool Filter

Diatomaceous earth, or DE, filters use tiny fossil skeletons as a filtering agent. The DE is placed into a grid system that the water runs through.
Crushed sand filter systems are being outlawed in a growing number of areas because of the need to back flush, which causes contaminated water to mix with groundwater supplies.


The new enhanced cartridge filters far outperform the old cartridge type systems and the other methods described here without being damaging to the environment; they are the future in pool filtering. I Hope this has answered your question on how do I clean a pool filter. https://waterfilter.my/

Sand filter maintenance

Maintain sand filters

Sand filters clean pools gradually by removing dirt, debris and particles as the water passes through a deep bed of sharp sand. If you charge and maintain your sand filter properly, you will be provided with years of trouble-free service.

The routine service method for sand filters is backwashing. One of the benefits of a sand filter is that it has the capability of operating indefinitely without the need for fresh sand. Whereas, with D.E. or cartridge filters, you must open them to clean them periodically and replace the media.

Depth filtration is the process by which sand filters clean the water. This process is accomplished when the dirt goes through the sand bed and is caught in the minute spaces between the grains of sand. With cartridge and D.E. filters, dirt and particles are caught on the surface of the media.

The sand filter must be backwashed routinely in order for the depth filtration to be effective. If backwashing is not done routinely, dirt and debris will build up on the surface of the sand bed. This will cause shorter cycles, channeling and inadequate filtration. However, if you backwash too often, you may also hinder the filtration process. If the sand bed is thoroughly clean, some of the dirt particles will pass through without being filtered. The bed will accumulate dirt and the filter will catch the small elements. From this situation, you may conclude that if you clean the media too much, it will prohibit the sand filter from working properly. https://waterfilter.my/

Pool filter lid and gauge maintenance


Maintaining pool filter lids and gauges

There may be leaks on the filter lids, either on the pressure gauge air relief valve component, or on the O-ring that seals the lid to the tank. It is often simple to fix a lid O-ring. Try removing it, cleaning it, turn it over or turn it inside out and put it back in place. If this does not take care of the leak, then you need to replace it.

If the O-ring is not the cause of the leak, it could be that the outdoor water filter is cracked on the rim of the lid or the tank where the O-ring is situated. Examine the areas that are prone to cracks and see if there are any visible hairline cracks, which may be the cause of the leak.

Also air relief valves could be causing the leak if they are worn out, or merely dirty. Some valves are equipped with a spring to apply tension, thereby creating a watertight seal. If the spring gives out, it will cause the seal to give out also. Other valves have an O-ring on the end of the part that screws in the valve to form a seal. If there is a leak with this type of valve, you need to completely unscrew the valve and take out the screw part to inspect the O-ring. Then you can take out the O-ring and replace it. You may also unscrew the air relief valve out of the T assembly; replace the valve and apply Teflon tape or pipe dope and screw it back in place.

Another part that feeds into the T assembly is the pressure gauge. If there is a leak at that point, unscrew the gauge, then put Teflon tape or pipe dope on the threads and screw it back into position.

If your gauge registers low or does not register at all, remove it and clean out the opening at the bottom of the gauge. Sometimes dirt or DE will clog the hole which will stop the water from entering the gauge.

If you take out a pressure gauge or air relief valve, secure the T with pliers or a wrench while removing the element because the T assembly can effortlessly come loose or break off the filter lid if it is not held securely while you are removing or replacing a gauge or valve.

The T assembly itself may come loose at the location where the nipple goes through the hole in the lid. Take off the lid and make the nut tighter from underneath the lid. You will not have this type of problem with filters where the nipple is welded to the lid, unless, of course, you break the weld. https://waterfilter.my/

Pool Filters, Swimming Pool Filters, Spa Filters, Discount filters

The filter is the hardest worked piece of equipment on your swimming pool or spa. Pool filters and Spa filters work round-the-clock to filter impurities so you can enjoy pure water. You’ll want a durable pool or spa filter that will remove even the smallest debris and sediments from your water. Here is some helpful advice to assist you in selecting a swimming pool filter or spa filter:

Sand Filters


These filters use – you guessed it – sand as the filtering medium. Sand filters look like large balls and they hold hundred of pounds of pool-grade sand. Basically, water flows into the top of the filter housing and makes its way down through the sand bed where the sharp edges of the sand catch the dirt. On a micron-to-micron comparison, sand filters remove the least amount of dirt – particles as small as 20 to 25 microns. But again for a time, the dirt left behind contributes to the filtering process. Sand filters certainly are efficient enough to keep just about any pool clean.

To keep a sand filter working, depending on the size of the filter you must clean it as often as once a week during swimming season. Maintenance means backwashing where the flow of clean water is reversed back into the filter. The problem with this, however, is that backwashed water is simply wasted. A typical backwashing session can waste a few hundred gallons of water – water that must be replaced in the pool.

Cartridge Filters
Cartridge filters have been around for some time, but they seem to be gaining in popularity in many parts of the country. They consist of a tank that houses three or four cylindrical filtering elements. The filters are actually made of polyester or some other material that can provide a superfine filtering surface. The fabric catches and holds the impurities until you clean or replace the filter.

The cartridge can filter out anything down to about 5 to 10 microns in size. A grain of table salt is about 90 microns; anything below about 35 microns is invisible to the naked eye. It is important to remember that with any filter a small amount of dirt actually aids the filtering process. In most areas cartridge filters are less expensive than diatomaceous earth filters but cost more that sand filters. However cartridge filters are more popular because of the minimal maintenance involved. Some families will find it sufficient to simply hose off the cartridge filter a few times during swimming season to keep them working properly. Others may need to soak the filters in detergent or replace them. In any case, maintenance takes only a few minutes to the filtration system in top shape.

Diatomaceous Earth Filters
DE Filters, these products can filter out dirt as small as 3 to 5 microns. If you opened the tank of a DE filter it would look somewhat similar to a cartridge filter. But the grids are packed with diatomaceous earth, a powder made up of billions of fossilized plankton skeletons. It is the powder that actually catches and holds the dirt.

DE Filters are usually the most expensive type, and they get your pool water cleaner than the other filters. But the necessary maintenance can be a drawback for some homeowners. Most manufactures call for backwashing to clean the filter. In backwashing, the system reverses the flow of water. The clean water cleanses the filter. The dirty water is drained from the system. more info at https://waterfilter.my/
