In other words, use a shop vac.....
This depends on the type of sand filter you wish to install.The basics are you have to find a good position for the filter, Put the laterals in place, drop the required amount of sand or filter media in it, screw the multi-port on top Connect the pump to the filter at the inlet have the return pipes connected at the outlet then you need to have a place to run the water to that comes out when you are doing a backwash. Seek advice from the suppliers of the filter to make sure you get it right
Is this for an above ground vinyl lined pool? Or a standard pool?
For the previous: You should have some hoses that are supplied with the filter if not you will have to find them at your nearest pool store. One hose will connect to the discharge side of the pump/the piece with motor attached. The other end of hose will be attached to the filter inlet. Second hose will be attached to the filter outlet and then the other end will be connected to the pool return / the nozzle going into the pool wall.
For a standard hook up Plumbing would be the same however, the hoses would be replaced with PVC pipe schedule 40.
Find a brand/model of sand filter that will fit in the physical space you have. Remove or replace fittings in order to fit the new unit. You may have to saw the existing pipes and/or use coupling reducers/expanders to make to new unit fit. Be sure that the modified fittings do now restrict the water flow below the minimum required rate of your new filter.
You don't change the filter on a sand filter, you back wash it. Unless you mean how to you change the sand in a sand filter. This is done by removing the multi port control from the top of the unit sucking out the sand with a venture made for the occasion (ask your pool shop) and replacing the sand. This needs to be done about every 3 to 5 years. Furnace Filters, Air Conditioning Filters at Air Sponge Filter Company

There is a broken or worn out lateral in the bottom of the sand filter. You need to buy new laterals and put new sand in the filter.
One way would be that the water never really gets crystal clear. A good rule of thumb is change sand every 5 years. Of course use the correct grade of sand and use the filter manufacturers recommendations for the correct amount. Ken
If you can blow through the filter with no constrictions it's fine.
Sounds like your filter needs to be cleaned: DE < BUY THE FITER CLEANER> SAND: GET NEW SAND CARTRIDGE: BUY THE FILTER CLEANER
Every year
of course. you should change your sand every 8-10 years. use a shop vac to get it out.
It is a cartridge type filter. Open your owners manual and read.
