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/
Investing in a good quality filter for your home pool is essential to maintain good health of yourself and your family. Sand used in filtering media is one of the best choices that you can make to ensure quality and affordability. Sand for sand filters is a low-maintenance alternative to DE or diatomaceous earth filters because these filters remove dirt and bacteria at a lower cost, and for a longer period of time.
The sand in these filters is somewhat finer and subtler than the sand found in beaches. Highly graded and specially formulated for filtering purpose, the average dimension of this sand lies within the range of 45 to 55 millimeters, and it possesses the ability to trap dirt particles as small as 20 microns. As the accumulation of impurities inside the filter increases, the pressure on the filter assembly rises. A very high amount of pressure on the filter may render it incapable of filtering properly; therefore it is necessary to monitor this pressure using the pressure gauge provided.
Whenever the value increases the figure of eight pounds, it is important to start the backwashing procedure so that the impurities and particles get discharged and the efficiency of the filter is retained.
In order to ensure efficient operation of these sand filters, regular backwashing is an essential feat. Backwashing not only retains the filter’s capability to work to maximum capacity and ensure uniform filtering, but it also retains the life of the filter media and sand tank. Backwashing automatically cleans your filter from the inside; therefore there is no need for manual cleaning as in the case of diatomaceous filters.
Hence this filter is an ideal choice for you if you are looking for the least amount of maintenance, long life and efficiency at an affordable and budget friendly price range. With adequate backwashing and rinsing, the filter media does not deteriorate over time and the sand inside the medium does not require replacement for at least seven years. However, if you experience the need to backwash every fifteen days or so, it can be a sign that your internal filter media has deteriorated. This deterioration is generally a result of hardness or mineralization of the water.
The pH of the water changes due to the presence of hard minerals like calcium, manganese and iron in the water. These metals deposit in the filter media and make the sand filters less efficient by reducing their quality level. In order to combat this problem you can either opt for a larger sand filter that has a bigger surface area, or you can opt for a water softening filter. Water softening filters oxidize the mineral content in tap water and reduce the level of hardness. In this way, metal accumulation in the sand for sand filters is decreased and they can work efficiently for a longer time.
Mode of operation of these filters is simple. The three basic settings common to all filters using sand are “filter”, “rinse” and “backwash.” Filter setting purifies the water off any impurities; backwash reverses the water flow and cleans the filter media, and the rinse feature is activated between filtering and backwashing for about 20 seconds. https://waterfilter.my/
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/
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/
There are several different factors to repairing and maintaining your filter, such as installing the actual filter: plumbing; cleaning it and keeping it clean; and of course, taking care of any problems that may arise.
To install your swimming pool filter, your need to follow some simple guidelines for the installation process. The important procedures are listed below, but first of all, keep in mind that it is only a basic guide and you need to check with your installation book that you received from the manufacturer
before you actually install your filter. You don’t want to begin cutting PVC pipe and greasing the O-rings before you know for certain what you need to do.
Examine the entire system, including the design, electrical and plumbing before you undertake the installation task. Some of the more simple tasks may make a big difference on how your filter operates.
You want your pool filter to have the best water flow possible, therefore, you need to carefully examine the plumbing. The plumbing should be devised and set up with the fewest lines and smallest number of fittings possible. If you need to install the filter somewhat of a distance away from the pool, the pipe size must be enlarged between the filter and the pool so that it will reduce the head resistance and make up for a longer run time.
A slab of concrete (either poured concrete or a concrete block) or brick make up the equipment pad on which the filter will be mounted.
It is best if filters are located as close to the pool as possible. Do not install a filter on a wood surface as it may warp or rot underneath the filter and damage the unit. The filter must be level when mounted; otherwise, it may cause the filter to vibrate or not operate up to its capacity. When you install the filter remember to allow plenty of room to work on your filter if the need should arise. Also make sure to have sufficient drainage.
The filter needs to be grounded since the pump motor runs on electricity even though the actual filter is not directly hooked up to electricity. Make sure you obtain the services of an electrician to undertake this procedure. The set up must conform with the local and national electric codes.
It is very important to integrate the filter into the entire circulation system, as well as the pool’s electrical system, which is why it is important to position the unit in the proper location. https://waterfilter.my/
High rate sand filters information
The method of filtration that has been in existence the longest is the sand filter. It is also the most popular type of filtration.
The high rate sand filters are usually .45 to .55 mm. The sand that is used with the filter is known as pool grade #20 silica sand. The sand filter separates the particles while allowing filtration to take place. This type of sand filtration is known as “depth” filtration because dirt is forced
through the sand bed, then trapped in small spaces between particles of sand. At first, the clean sand filter will eliminate large particles, but as the sand bed collects more dirt, it will eliminate the smaller particles as well.
When sand filters are in the filtration mode of operation, the water will always flow from the top to the bottom. Clean, filtered water is able to pass through the filter through a lateral or under drain that contains slots to hold back sand.
Cleaning is an important process of maintaining your sand filter in order for it to operate at optimum level. It is also important to extend the life of your other pool filter equipment.
The sand filter is cleaned by reversing the flow through the filter to the “waste” line. This process is known as backwashing. The filter should be cleaned on a regular basis, approximately once a month. You should carefully read your filter instructions to learn how to reverse the water flow in
order to properly clean the dirt and debris from the filter.
The sand in a crushed sand filter should be replaced every three to five years. Of course, this would depend on how often the pool is used during the season and the types of contaminants in the air that come in contact with your filter. https://waterfilter.my/
Everything Pool Filters – Importance of Good Water Balance For Your Swimming Pool
What good water balance means to you…
Our customers ask, “why do I have to worry about testing & balancing my swimming pool water? If it looks clear, everything must be good. Right?” The answer is, “Usually not.” The short answer is if the water isn’t properly balanced, you’re not safe, the pool & its components (filter, pump, heater, pool surfaces, fittings, etc) just won’t last long, and finally, you’ll be wasting your money!
Here’s what we mean:
Pool Waterbalancing for you & your body: When the pH & Total alkalinity are out of balance, your chlorine, bromine or other sanitizer don’t work as efficiently as they should. When the sanitizer doesn’t work efficiently, bacteria & other stuff you don’t want in your spa start gaining control. You could easily end up with skin rashes and eye irritations at least.
Pool Water balancing for your pool: Without proper chemical maintenance, you can get water line scum build-up, much shortened heater life (the heater either corrodes away due to low pH & Total Alkalinity; we’ve seen people buy 2 heaters in one season because they don’t think they need to balance their water!) or scale build-ups (high pH, high Total Alkalinity, high Total Hardness) prevent efficient heating (scaling of the thickness of just 1 sheet of paper can easily cause you to use at least 10% MORE electricity or gas), clogged filters and shortened filter life. Left completely alone, we’ve even seen the pool liners become faded & brittle & other damage because of it’s constant contact with out-of-balance water. Consistent, low total alkalinity & especially calcium hardness over a period of several months can lead to a shortened vinyl liner life (lots of little, tiny pinholes – no warranty coverage). You didn’t buy your pool for that mess!
Remember that the source water for filling your pool can have certain properties that can cause chemical changes as you top off your pool; especially pH, total alkalinity, calcium hardness & metals & minerals. If your tap water is “soft” or “hard”, those chemical make ups, make a difference. The use of water softeners makes a difference. Certain salts will directly affect the water balance.
Here are the proper water balance parameters to keep in mind:
pH – 7.4 – 7.6
Total Alkalinity – 80 – 120 ppm in concrete pools, 120 – 150 ppm in vinyl or fiberglass pools
Calcium Hardness – 200 – 250 ppm in concrete pools, 175 – 225 ppm in vinyl or fiberglass pools
Total Dissolved Solids – less than 2500 ppm (in NON-salt pools)
Iron or Copper – ZERO
Cyanuric Acid – 40 – 100 ppm (chlorine pools ONLY; bromine CANNOT be stabilized; biguanide pools – Soft Swim or Baquacil – do not require stabilizer)
Maintaining Total Alkalinity & Calcium Hardness in the middle of their respective “good” ranges is just a really good idea. Everything works just the way it should. The water looks great, feels comfortable, chlorine & bromine are acting properly, water balance is bouncing around.
Rain water can dramatically effect your water balance, depending on its pH & obviously the quantity of rain. The pH of rain varies across the country generally becoming more acidic as you go from west to east. As rain falls, it carries down particulate matter that is suspended in the air. This suspended particulate is dust, dirt, soot, chemicals, even bird droppings.
Adding fresh make up water after evaporation or backwashing will eventually have an effect on the water balance. Additions of more than 2 inches of fresh water should be allowed to circulate for 24 hours then tested to make any necessary adjustments.
Also keep in mind that rain water (especially when heavy or copious) can add to chlorine demand.
Wasting money: I think you’re beginning to understand the reason why from the above information. You’ll be purchasing more chemicals when you don’t need them. More frequent filter changes (proper cleaning of the filter cartridge should give a life of 2 to 3 years minimum, DE filter elements should last about 5 years with proper cleaning & maintenance). Par Pool & Spa wants you to have fun. Proper water balancing, testing & care shouldn’t take more than 15 to 20 minutes per week on average.
Be sure to test your water with a good quality test kit or test strips. Remember to change the strips or testing reagents each swimming season. For added accuracy seek out a local pool professional who is able to properly and thoroughly test your pool water filter. These test need to include: Total chlorine or bromine, Free chlorine, combined chlorine, pH, total alkalinity, acid demand, alkali demand, calcium hardness, total dissolved solids, water temperature, mineral or salt level (saline or salt chlorine systems), iron and copper levels. Don’t wait to adjust the water balance. Like most things, it costs more to fix than to maintain. https://waterfilter.my/
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:
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 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/
