Im not sure of this answer as I am a new pool owner but I believe when the term backwash is used, it regarding cleaning a sand filter system. I think this is the only way to clean a sand filter without replacing the sand. That answer is pretty much spot on. Backwashing reverses the flow of water in the filter - instead of going from top down, it goes bottom upwards. The purpose of this is to dislodge dirt from the sand filter and send it out the waste pipe. This is the correct way of cleaning a sand filter and should be done every 2 weeks or so, or when the pressure gauge reading INCREASES. Yes, backwash reverses the flow of water in a sand filter to clean the sand. You should backwash when the pressure increases by 5PSI (roughly every week). The sand only needs to be replace every 10 or 15 years. People often confuse the pump with the filter. The filter is the big tank with the valve on top marked filter/backwash/rinse, etc. The pump is what moves the water and has a small basket to catch leaves.
I would only add to the above answers -- If you have a very small sand filter back washing the filter every two weeks may seem adequate because of the volume or capacity of the tank. Larger filters more adequately sized and matched with the rest of the system better serve you, possible use less water in backwashing, can wait to be backwashed up to 4 or 5 weeks. A sand filter that is slightly dirty will work better at cleaning the water than an extremely clean one. Again the pressure on the gauge is the best indicator with the exception of the occasional filter unit and gauge that will not register an increase until the filter is absolutely packed. As the saying goes in the industry "bigger is better" applies to most cases here.

How do you backwash by cleaning a pool without a pump?
You can set up a siphon hose if your pool is on a hill, otherwise, buy a pump. Hatawa
How do you bachwash a hayward pool pump?
You don't backwash a pump, you backwash sand and D.E. Filters. To clean them you change your valve to the backwash setting. To clean a pump basket you turn off the pump, open the lid and pull the pump basket out, dump the contents and place it back into the pump and replace the cover. You may or may not need to prime the pump before you turn it back on.
Do you need to bring pool pump and filter indoors?
No , if you have a D.E. filter instead of an older cartridge filter than the D.E. can get pretty messy if when you filter clean , and if you have a backwash when you backwash .
Pool skimmer not working?
Empty the skimmer baskets and the basket that's attached to the pump. Then backwash and rinse the filter.
How do you calculate the required pool filter backwash rate in gallons per minute and backwash volume in gallons?
how do i calculate the volumn of backwash in a pool
Do you shock a pool or backwash pool first?
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
Your pool pump was running 12 psi now it only runs at 5 psi what is the problem?
you have to backwash your pooluntil it starts coming out clear at the end of the backwash hose about 3-4 miuntes
Where does pool backwash go?
It goes out the backwash line. This is usually either plumbed into the line, and either goes into the sewer, or out on the ground. Some setups have a hose that you unroll, and attach to a port on the valve. I found my discharge by putting the handle on "backwash", turning the pump on, and looking around! Mine happened to go out into the back ditch. Took all of about 10 seconds to find it.
Where is the backwash knob located on the swimming pool pump?
The "backwash knob" - usually called the handle - is located on top of the filter or just to the side of the filter on a sand filter. They could be on the very bottom of the filter or to one side of the filter but never on the pump. The filter is the large tank.
How do you know when you need new sand in a Hayward filter for an inground pool?
Depending on the size of the pool and the size of the filter and the amount of times you have to backwash, also if you have had a lot of rain then you may need to backwash more than usual. If you put the pool in and the filter and you know how old the sand is, if you are backwashing more than usual,change the sand. Also before you backwash check the pressure of the water going back into the pool, then backwash check the pressure again the pressure should for any size hayward pump push your hand away if it does not then change your sand.
How do you construct a sprinkler system with the pool's backwash discharge?
I am in the process of developing the same idea. My thoughts are to get rain water collection barrels and fill them with the backwash and add pump that is fed by the barrels to generate enough pressure for a few sprinlkers.
What kind of in-ground swimming pool maintenance is needed over winter in cold climates?
To winterize your inground swimming pool, first backwash the filter, and then disconnect the pump. Purchase winterizing chemicals for the pool water, and be sure to use a pool cover.
