In one case the debris and other particles have been filtered out past the sand, a pump moves the make clean water dorsum into the pool. As more than droppings becomes collected past the filter, the efficiency of the filter volition start to increase likewise; the debris will actually help to keep smaller particles from passing through the sand. In lodge to ensure consistency and brand certain that most if not all of the debris that might be in your pool water is filtered out, sand of a specific makeup and grain size is used. Sand filters use #20 silica sand with grains that fall inside the 45 to 55 millimeter range.

Materials Filtered by Sand

A range of materials will be captured by your sand filter. Larger materials such as leaves, gravel, and insects won't exist able to pass through the sand at all, and fifty-fifty smaller materials will be stopped as the water from your pool moves through the filter canister. Fifty-fifty small particles between twenty and 100 microns in size volition exist captured by the sand within your sand filter, and particles smaller than that can potentially exist contained as the filter collects droppings. Particles that pass through the filter initially may be filtered out later as the water in your pool cycles back through the filter.

Maintenance Requirements

The more dirt and debris your filter has in it, the more pressure will begin to build within the filter canister. Take annotation of the initial reading of the pressure approximate on your swimming pool's sand filter, then cheque it every calendar week or two to see if there has been an increment in pressure.

Kickoff by performing a backwash, leaving the pump turned off in one case it is finished. Open the pressure valve on the top of the filter canister to release the force per unit area from within the sand filter, then open the drain valve on the bottom of the canister to release the h2o inside. Begin loosening the bolts property the canister together, alternating from 1 side to the other in social club to prevent dissentious the container with excessive stress on 1 side. Remove the top of the canister, then scoop out the sand contained inside of the filter canister. One time you've removed the sand from the filter, check the lateral components inside to see if they are overly loose or broken. Replace any laterals that have broken or come loose, then fill the container half full of water to assistance protect them from damage as you start adding sand. Pour or scoop clean sand into the container, filling it to within an inch or two of the top; consult your puddle filter's possessor'south manual if y'all aren't sure of exactly how much sand you should add. One time the filter is full of sand, reattach the top of the canister and perform another aftermath before you begin pumping h2o through the filter again.
