Hi.. backwashing is pretty easy. you didn't mention if you have an inground or above ground or what type filter you use.. but, it's all basically the same thing. First, turn the pump off, then, set the backwash lever to open. Turn on the pump. Let it backwash the water for one minute. Turn the pump off and close the backwash lever. Turn on the pump and run for 20 seconds. Turn off the pump, open the lever again, backwash, turn off and then repeat the 20 second run cycle. Three full cycles like this will usually do the trick.
You can back wash to waste only if you have that type of back wash valve that will do just that. If that is what you mean. If you mean, vacuuming the dust, sand, bugs, leaves and other small stuff, then you use a pool vacuum and vacuum hose either in the "filter" mode or the "vac to waste" mode. Please state just what you wish to do.

If the pool is really dirty then it is best to set the filter to waste.

You may have to check the seals in the multyport on top of the sand filter.
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.
You can not measure the pressure in a swimming pool. If you mean the pressure on the filter tank gage then you may have to backwash the filter. Talk to your local pool store for instructions as how to maintain a swimming pool and the equipment. Get some education on swimming pool maint. before you get into some real trouble. A pool is not too forgiving for someone without a basic knowledge of pools.
how do i calculate the volumn of backwash in a pool
Your sand filter multihead is either in the backwash, rinse, or waste position. Move it to the filtration position.
Just backwash until it is at the level you would like it to be. Or get a floating swimming pool skimmer ond take advantage of the free water and save on pool salt if you have a saltwater chlorinator.
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
It just stays there. some is lost to the backwash , splashing, overflow and so on but the salt that is in the water stays there.
No it is working as one would normally expect. swimming pools don't normally have an over flow fitted so the pool just keeps filling up past the static skimmer. the only way to fix it is just to backwash the filter until it is at the right level again. or if you don't want to waste the water get a floating pool skimmer.
No absolutely not unless you want to waste a lot of water you backwash a pool when the pressure in front of the filter becomes too high or goes into the red.
