What should you do if the top of the sand filter and the fingers at the bottom have both been replaced but there is still sand in the pool and you have already tried backwashing?
Many people mistake "mustard algae" as sand in their pool. Does the sand briefly disappear when you run a pool brush over it? Mustard algae resettles quickly and looks very much like filter sand. We have helped many customers with this problem. Also, if there is truly sand in the pool and you have replaced the laterals, check for any leakage of air around the filter. You may hear or see cavation in the pump when it is shut off.

\n Phosphates \n. \nIt sounds like you may have phosphates in the water, do you have lots of leaves or the aftermath of seeds from the trees blowing in your area, I had poplar tree seed casings white fluffy things and it gave me this problem.\n. \nSolution is a product called phosfree. \n. \n… Backwash after replacing sand \n. \nI always change my filter's sand once per season, unless there is a high concentration of leaves and other debris being vacuumed up daily. Then I will change it out mid-season as well.\n. \nAfter changing the sand, I always backwash the filter for at least 5 minutes. That way the pulverized dust and other small particles in the sand get whisked away, instead of going into the pool.\n. \n Could be your algaecide \n. \nThe sand under normal use should last 5 to 10 years if it's backwashed well enough. The foam could be caused by the algaecide used. The usual reason for replacing the sand is when sand is returning to the pools or it is no longer effective. You should check with your local pool chemical supplier. Most pool sales and service companies supply free water testing when you are a customer. ( Full Answer )
When you back wash (if you you have a salt water pool turn of chlorinator while you are doing this) (1) stop the motor (2) reposition the lever at the top of the sand filter to the backwash position (3)turn on the pump (4) Normally you will see a clear plastic bubble sticking out of the si…de of the multi port, when its on back wash you will note the water in it turn dirty (cloudy) run until it clears and then stop the motor. (5) now turn the lever to the rinse position you will note some cloudiness in the bubble usually I run it for about 30 seconds. (6) reposition the lever to filter and don't forget to turn on your chlorinator. ( Full Answer )
Answer . The sand has to be scooped out or can be shop wet vaced out. Replace with #20 silica sand only but first add water to the filter tank to about half way and cover the stand pipe in the middle of the filter so the sand will not spill into it. k
What should you do if you have an above-ground pool with a sand filter and the pressure gauge is only reading at 5 but you changed the sand in the filter and it still won't raise the pressure?
You may need a new pressure gauge. They are inexpensive and can be found at any place that sells pool products. OR That may be all that you are going to get out of the system you have.
\n . \n Answer \n. \n . \n . \nTurn off the pump. \nRemove the filter drain plug and allow filter to drain. \nRemove the filter dome, if your filter doesnï¿½t have a dome you may have to remove the multiport mounted on top of the filter. \nUsing a wet/dry vacuum suck out the old sand an…d discard, be careful not to damage the laterals at the bottom of the filter. \nSlowly add new sand and spread around the inside of the filter tank. \nPut the filter back together. \nReplace the filter drain plug. \nTurn on the pump. . ADDING this is a acceptable way to change out the sand of your sand filter, just keep in mind that if you have a multiport filter head then you must make sure the lateral assembly, the pipe in the filter, does not get any sand in it. sand in that pipe will add sand to the pool when the filter is turned on. Also you need to make sure that the pipe is centered in the filter before and during the adding of the new sand to the filter. If the pipe is not centered it will not allow the filter head to sit properly down on the filter and can lead to the possibility of leakage from the clamp where the head and filter meat. . So in short you can use the wet/dry vac. . just remember to keep the lateral assembly (pipe) centered and not allow any sand down in the pipe. . ( Full Answer )
Remove the multi port control from the top of the sand filter . remove the sand inside the unit, this can be a next to impossible job to do by hand as they are not really built with this job in mind, however help is at hand with a little venturi pump that hooks onto your garden hose that will suck …the sand out of the unit without having to scoop it out see your pool shop about getting hold of one of these. . When its empty replace the sand or whatever media you are using and screw the port back on. You can also suck the sand out using a plain old shop-vac. ( Full Answer )
How do you get the pressure down on a sand filter pool pump if you have backwashed and it hasn't changed?
Pressure Gauge/Backwashing . What is the normal reading on your pressure gauge? It is a possibility that the gauge itself is broken. Those pressure gauges do not last very long and usually break within the first year. I have found them for as little as $13.00. You may try that first since backwas…hing was the correct thing to do when the pressure went up. ( Full Answer )
The same as any pool. you plug the vacuum hose into the vacuum plate over the top of the leaf basket, connect the vacuum head to the end with the pole on it leave the sand filter on filter setting and vacuum the bottom.
How do you stop sand from coming into the pool after you have changed the sand and cleaned the pool and backwashed it?
Answer . There are two possible problems.. 1. The filter valve gasket needs to be replaced. If the gasket is bad it will allow sand to pass through the filter ports and either enter to pool or go into the backwash line.. 2. The laterals in the bottom of the sand filter are damaged. You will nee…d to remove the sand from the tank and inspect the laterals. You can see a diagram of the inside of a sand filter here http://everything4pools.com/parts.php?cPath=56_64_103_131. Answer #1 is wrong !!. You have inadvertantly dumped the sand into the filter without covering the stand pipe coming up from the lower center of the filter. The sand may eventually stop coming thru as it is consumed by sending it out to the pool. The stand pipe is full of sand and will take a while to clear. You could open the filter and remove all the sand and start over after removing the stand pipe and cleaning the seat or the stand pipe. Once cleaned replace the stand pipe then tape a cup or a heavy plastic over the top of the stand pipe then refill the filter with the #20 silica sand. Once you have added all the required amount of sand then clean the seat and o-ring area before mounting the valve. Start the filter in the B/W position and run briefly to clear, stop the pump and rotate the valve to "filter". ( Full Answer )
\n. \n Changing Sand \n. \n . You just take the top off and start scooping the old sand out either with your hand, a large cup or a powerful shop vac. You will never get all of it out, but don't worry about it. It takes a couple hours to get the old out and put the new stuff in. Make sure you… backwash the filter throughly after putting the new sand in to get all the dust out.\n . \n . Contact your local pool company. It isn't that expensive and it's worth letting them do it properly. ( Full Answer )
Answer . When you back wash or after Back wash??? When: Damaged B/W valve. After: Broken laterals or wrong type and size sand used.
Answer . By using the features on your filter's back wash valve, vacuum the D.E., after it has settled out, to waste. You may have to do this several times depending on the amount of D. E. you added. If you added no more than a cup or hand full ~ just vacuum as usual as this small amount may enh…ance the filtration. ( Full Answer )
o you back=Answer . DE filter, sand filter: Notice and mark the filter gage at the number which registers the lowest reading when the filter is at it's cleanest. Use a Sharpie. When the pressure goes 8 to 10 #'s above that mark it is time to back wash the filter. If your gage is not accurate, old…, damaged or just doesn't work. a good rule of thumb is about every 30 days. You will also sense a decreased amount of suction when vacuuming the pool. Back wash then too. Cartridge filters: About the same as above but now you have to disassemble the filter to hose off the cartridge(s). k 9/4/07 ( Full Answer )
Answer . I have always either broadcast the used sand over the lawn or mixed it thoroughly with the soil. Works with clay soil.
The correct expression should be how do you back wash a sand filter. sand filters need back washing when the pressure on front of the filter gets too high. This is done by, stopping the pump and swinging the lever on the top of the sand filter to the backwash position, usually the opposite position.… Start the pump. Usually there will be a clear buble near the lever, when the unit is on backwash you will see cloudy water rushing around in it , wait until it clears up, stop the pump again. swing the lever to the rinse position. start the pump and let it run for about 30 seconds or until the water in the bubble runs clear again . Stop the pump. return the lever to the filter position and bobs your uncle, done, ( Full Answer )
Other than putting on backwash to reduce suction what can you do to open top on strainer basket next to sand filter if it will not open?
That depends upon which type of pump you have. In any case you would have to turn off the pump and make sure it will not come on while you are servicing the pump. If it is a StaRite pump you may need a lid removal tool. There are a few different ways that a pump lid can be loosened, removed, tight…ened or secured. Some screw on, some are just placed into position and secured with a clamp or wing nuts. Hayward has both screw on and press on lids. StaRite has both - - - as do most manufacturers. If you have not serviced the o-ring on your pump for a while it will be difficult to remove a screw on lid without specialty tool to do that. ( Full Answer )
Why does the filter blow sand back in the pool after backwash even after letting it set for several minutes?
It sounds as though one or more of the laterals in your sand filter are in need of replacement. when these become worn they do not hold back the sand in the filter and it ends up in the pool.
Ideally none! You will always get a bit in there from people bringing it in on their feet, and from the wind blowing in in but you should try to keep it well-vacuumed so that the water stays cleaner and so that your filter will last longer.
If you have a sand filter your laterals are worn these are the spokes at the bottom of the sand filter that allow water through but not sand.
If sand from the filter is ending up in the pool then the laterals are getting worn. These are at the bottom of the sand filter and should only allow water to pass.. A: You have a bad lateral(s). You need to remove all of the sand from the filter in order to get to the laterals. Some laterals eithe…r unscrew or click or press into place. Once the lateral is repaired replace the sand with new sand using a #20 grade filter sand. k ( Full Answer )
Go to your pool shop and they will be able to supply you wit a Venturi pump these hook onto your garden hose and can suck the sand out of the sand filter.
\nWhy would you want to? Sand doesn't wear out. Sand Filters don't do a very good job of cleaning Pool water Until they develop a layer of hair, skin and other debris like bugs etc on top of the sand. Even then, a Cartridge Filter and DE Filter do a much better job.
most multiports on sand filters have the following settings. Filter Runs the pools water from your pump through the filter media then back into the pool. this is the setting that is nearly always used. . Backwash Runs pool water from your pump over the filter media and out to waste. This removes… dirt that has been collected during filtration. A backwash is required when your pressure rises about 10 pounds over the normal pressure. Most sand filters have a clear bubble situated near the multi port where you can see the water running to waste, watch it and you will see that the water is dirty at first run the backwash until it clears then stop the pump. . Rinse Runs pool water from pool through the filter to waste further rinsing the top of the filter media. this should always be done after backwashing to stop cloudy water returning back into the pool . Re-circulate Simply keeps the water circulating from the pool through the pump and back into the pool. It does not put the water through the filter, stops the water from stagnating but still puts it through the static skimmer. . Winter/Closed shuts all the ports and is used when the pool is winterized shut down or to stop water from passing through the valve. . Waste Runs Pool water directly to waste without running it through the filter. This setting if manually vacuuming the pool and the dirt load is too high for the filter to handle. It is also the setting that is used for hand vacuuming when removing settled contaminant and flocculate after flocculating the pool. . Never keep the pump running when changing the setting on the multi port as it will cause it to be damaged. ( Full Answer )

Consult your manual for the correct valve position your valve will be located on top of the sand canister, it generally should be labeled, however if it isn't or you can't find your manual with the specific position you can usually find a manual online, after this connect your waste line and set you…r valve to backwash, do this until the water begins to clear after this, shut down your pump and switch to rinse cycle while rinsing watch for the look glass tube to become clear if your pump does not posses a look glass generally 3 minutes if rinsing is enough, after this your pump is ready to resume normal filtration, ( Full Answer )
We suggest using the White Silica Filter Sand or Brown Filter Sand (white is my preference). These can be found at any local pool store. Remember before pouring new sand into tank to fill tank at least 1/2 way with water to break the fall of sand onto the filter elements. I like the white silica bec…ause it comes cleaner and usually a bigger grain so it filters better (my opinion) I have had brown sand delivered and it has had fleas in it before again just my preference.. visit www.prospectpoolsllc.com or www.prospectpoolsllc.com/blog ( Full Answer )
Generally speaking, it's a broken lateral in the sand filter. it a new pump from last year and the problem began last year befor I close it up
When the sand feels really smooth. Filter sand or Silica #20 grade pool sand is sharp sand. The other is that it will start to clump together as it starts to round off.
For aesthetics it usually looks better to have a smooth bottom. In most cases it will not effect the liners fit of function. Upon new installation you may notice some inconsistency in the bottom as it's hard to install without disrupting the sand. Some of this will likely flatten out as the weight o…f the water acts upon the sand. ( Full Answer )
A good way for getting sand out of a sand filter is to get a sand venturi with this attached to the end of a garden hose you will be able to suck all of the sand out of the unit easily. Check with your pool shop as they may be able to sell, hire or lend one to you.
Backwash a sand filter with a multiport valve;. turn off the pump motor .

Shut off pump motor and move multiport valve handle to the RINSE position .Run on rinse for 15 - 30 seconds. once again you can keep an eye on the clear bubble to see the water clear if you have one. . Shut off pump motor again and move multiport valve handle back to the FILTER position . Now start pump again on and take note of the lower pressure. when the pressure gets too high again it is time to backwash once again. ( Full Answer )
Well if dirt comes out then you should clean off your feet before you get in,becouse your fet carry it in the pool then when the filter sucks up the dirt then the filter gets too much dirt in it and spits it out and you should proble clean the filter out once a month!
Sounds like top of filter is broken. There is a spider gasket inside there to separate all the different chambers. Is it backwashing at full force or just a little?
It depends on how big the filter is. 18" or 24" If it is a 18" three 50 lb bag will do. I believe with the 24" it is 4 to 5 bags. I have a 19" and used 3 bags.
Sand filters usually have a pressure gauge in front of them indicating the back pressure before the filter.When the filter needs to be cleaned this pressure gets high. usually it has a red section on the gauge. When it hits the red it is time to think about back washing. If the gauge does not work a…s so often happens with these things. you can usually judge it from the lack of suction coming from the filter. After backwash you will note the pressure will be down and the suction will be up. ( Full Answer )
That can change from pool to pool, In most cases if the pressure indicator is up to about 3./4 of the way it is time to backwash. this coincides with weak suction.
Most likely you have a sand filter unless you live near the beach. The sand filter has baffles inside the filter and buried down in the existing sand. One or more of the baffles or the stack pipe is cracked. causing sand to return to the pool with the filtered water. Drain the sand from the sand fil…ter and replace the baffles and/or stack pipe. Replace with new sand. Be sure to use approved sand for sand filters. ( Full Answer )
After 13 years in the pool business the best way I have found yet is to use a shop vac.
The best way to determine this is to backwash the filter and see what the pressure is at that time. Then go 7-10 PSI above that and this will be your pressure to watch to tell you when to clean your filter.
The techinique I have used works pretty well but you have to remove the sand pile. 1) Open drain on bottom of filter. 2) Remove top valve assembly. 3) Remove sand screen from drain valve - needle nose pliers work. 4) Fill filter with water - a sand slurry should start from the drain. 5) Use a rod… or screwdriver the periodically clear the drain to keep the flow going. 6) Add water and hose down the sand in the filter as needed. 7) Move the sand away from the drain to keep the flow continuous.

Backwashing is done to clean the filter media in sand and DE systems. Cartridge filter systems don't have a "backwash" provision. You just remove the cartridges and wash off the dirt and debris with a hose.
i too would like to know, some here say 5-6 years old but pool professional told me 1-2 years im confused. :/ As the Installation and Service Manager at abovegroundpros.com, your sand in your sand filter is expected to last around 4 yrs. There are factors that can lessen the time frame and other…s that can lengthen the time frame. I recommend all to change out every 3-4 yrs as a rule of thumb. This will help make sure that your filter sand does not get overly filled with debris, causing your filtration system to not work at its peak performance. Remember to always backwash your filter after you have changed your sand, before placing it on filtration. In cases like this its better to be safe then to be sorry. ( Full Answer )
Considering that wholesalers TYPICALLY do not sell to anyone without a contractors license or at least a pool license, I'd buy it online. I wouldn't go to a Leslie's type store because of high prices. But it won't hurt to ask. TRY ONLINE.
this usually means that the multiport valve in the filter head is bad.. the gauge is not always accurate. replace gauge. the impeller in the pump can also be cloged not allowing you to get any pressure in your gauge. the backwash will be very slow if not any..
You don't . You chlorinate the pool with chlorine . You filter the water with a sand filter.
If the filter is not running properly after back wash (still dirty) you may need to replace sand it is very easy but can hard on your back. The basics of changing filter sand are remove valve from top of filter, disconnect any hoses or pipes on filter, lay filter on its side and roll around to loose…n up the sand, reach in and remove sand with your hand be careful not to damage the fingers in the filter they are expensive and can be very difficult to replace. After all the sand is out hose out filter and refill with new filter sand hook all hoses and pipes back up and you are done. Good Luck ( Full Answer )
Maybe you just think its your pool and its really the beach. The beach has a lot of sand.
Because dirt and small sand will pass through the filter the first time it is run after backwashing. By rinsing you are sending that debris, which could cloud your pool, out of the backwash port instead of back into the pool.
It's hard to answer without some troubleshooting. The first thing likely is a bad seal in the valve. First look to see if water is coming out of the waste line where water comes out when you backwash. You will also be losing water if that is happening. You could also have leakage to other sections t…hat will recirculate and you won't see water coming out of the waste line. Check the skimmer basket. If it is full it will not let sufficient water into the pump. Check the clear pot going into the pump. Is there air mixed with the water there. If so there is probably a bad seal on the cover, a plugged line between the skimmer and the pump or a skimmer full of trash. there can also be a leak inside the filter letting it bypass the filter media. Also check the gauge to make sure that it is accurate. They are cheap and easy to replace. There is a small curved tube inside that can become distorted by age or freezing. ( Full Answer )
The pressure gauge will generally read 10 PSI higher than when the filter was clean. In any case do not let the filter gauge go above 40PSI.
