You vacuum waste from a pool with a pool vacuum connected to a pole to push it around the vacuuming devise is plugged into the suction of the pump.

If you wish to vacuum to waste on the other hand you will first have to turn of the pump then turn the lever on the top of the filter to waste. This will dump the water, so don't vac to waste any more then you have too.

You vacuum to waste whenever you have alot of dead algae or debris and you don't want it to recirculate thru the filter back into pool. The sand filter will catch some of it but a portion will return thru inlets. So if you have alot of dead algae or debris then vacuum to waste. You will have to add water back and rebalance your pH and chlorine levels.

With above ground sand pool filters when you need to vacuum should the pump be on filter position or vacuum to waste?

It should be on filter and don't forget to backwash at least once a week.


When you vacuum dead algae from pool to waste more return when filtering with sand filter Do you need to replace sand?

Nope, Just as long as you turn your dial to backwash , waste and then rinse, You shouldn't have a problem. Watson's told me the filter sand should be good until 7 or so years. Until you cannot see any sand in the glass part on your filter, you should have it replaced.


Can alum be used to clean an above-ground baquacil pool whose sand filter is leaking sand into the pool?

Alum is a floculent and these are often used to settle excessive amounts of dirt to the bottom of pools the are available from pool shops. It sounds like you will need to replace the laterals in your sand filter first so that you don't have this problem in the future. Take care vacuum the settled dirt and flock to waste do not put it through the filter.


How did you get sand in the bottom of your pool?

If you do not see your water level going down on above ground pools they use sand for the bottom. My first guess would be that if you have a sand filter that the sand is coming from the filter just a bad or faulty gasket I do not know if you change the sand in your filter or you have someone do it, just have the person vacuum the sand up with the pool vacuum. have someone open the filter up and look at the gasket. A thin coat of sand? Well if is all over the bottom of the pool it is either a fine sediment that the filter cannot pick up or DE. If you have a DE filter and it is DE on the bottom of the pool you either have a problem with the internal components or, if you have a multiport valve, you may have a problem with that. What ever you have the best way to get rid of it is to vacuum it to waste. If you have a multiport valve you should have a setting marked waste and you would vacuum the pool while the valve was in this position. This bypasses the filer and run the water out the backwash line. Any other filter configuration I would have to know what type of configuration you have to advise you on how best to deal with this issue. If this "sand" is all in one spot by the return jet then you probably have a broke lateral at the bottom of the filer. You will need to replace the lateral and if the laterals are over 6 years old replace all of them.


Why does dirty water comeback into the pool while you are vacuum the pool you have to vacuum to waste?

The particles are too fine for the sand to trap, sand filters trap particles down to 25 microns. Dead algae can be a lot finer than that. The only filter that can trap real fine particles down to 3 microns are d.e. filters.


I just moved into a hose that was empty for 2 yrs pool was a green mosquito haven now just cloudy blue was advised to vacuum the deep end pump to waste but unsure how to do that HELP please?

Sand and DE filter have a multi-port valve that has setting labeled backwash, filter, recirculate and waste. by turning the handle to the the waste setting and vacuuming the pool you will flush the water out the waste line and not through the filter and back to the pool. Cartridge filters do not have these valves, you clean it by taking the cartridge out and hosing it off. you will not be able to vacuum to waste without adding a valve and a dedicated waste line. I have known pool owners to take the lid off the cartridge filter and vacuum letting the water overflow the top; not recommended, it will create bigger mess, and possibly ruin your pump motor. Try shocking pool with strong shock, using a clarifier and running pool 24/7 while cleaning the filter at least one or twice a day. The more you filter and clean it the faster it clears up.


Why is there sand in your inground swimming pool we use a DE filter?

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 enhance the filtration.


How do you get rid of dirt in a swimming pool without a vacuum?

This sounds as thought the laterals in your sand filter are worn. Laterals are horizontal spokes at the bottom of your sand filter with tiny holes in them that let water through but not sand. After a time the holes get enlarged and start allowing sand through and back into the pool


I accidentally vacuumed dirt in my pool using backwash mode instead of waste mode. How do I get the dirt out from under the sand?

There wont be any dirt under the sand. When you vacuum your pool you should do it on filter mode Otherwise you will lose a lot of water for nothing, this would be especially wasteful in the case of a salt water pool. Ofter having vacuumed the pool on filter mode and if the pressure gets too high backwash. after backwash rinse for a minute, then return to filter.

Nothing if its a sand filter However if sand is coming into the pool from the filter then you may have to replace one ore more laterals in the sand filter as they have worn and are letting sand through to the pool,
