Filtering your pool keeps the water clean and clear, for healthy swimming. Waterco pool filters employ sand as the filtering media, running the water constantly through a layer of sand to remove any impurities. Proper maintenance of the filter requires that the sand be changed on a regular basis every four to five years. Changing the sand should take less than an hour to complete, after which you can enjoy sparkling clear water.

Clean the old sand contained in the filter before removal. Turn the selector switch on the filter to the "backwash" setting and backwash the pool water through the filter for three minutes. Rinse out the sand contained in the filter with clean water for 20 seconds; then repeat the process.
Set the input and output valves on the filter to closed positions. Locate the filter drain cap plug slightly above the filter base. Set a tray or bowl beneath the filter drain cap plug and remove the filter drain plug cap, to drain the water contained in the sand.
Remove the filter lid by unscrewing it from the filter base. If the lid sticks, use the specially created Lacron lid tool, found at the same place that sold the filter, to remove the lid. Place the tool over the rim of the lid and twist the lid open.
Remove the air bleed cap and header tube located inside the filter. Use a Phillips head screwdriver to remove the screw on the inner top edge of the filter securing the header pipe to the black airbleed tube. Remove the header pipe from the tube.
Take a wet/dry vacuum with a hose attachment and suck out the old sand contained in the filter. Make the sand more fluid and easier to remove by adding a small amount of water to the sand to break it up. Wash the filter using a hose to remove all traces of the old sand.
Fill the filter about one-third full with water. Cover the airbleed tube opening inside the filter with tape to prevent sand from clogging the piping system.
Close the filter drain cap plug and then pour the new sand into the filter slowly, using the water to cushion the sand's fall. Fill the tank to the water level and then stir the sand around to level the surface. Continue to pour the sand until the filter is filled to the height indicated in the filter manufacturer's instructions. Generally, residential filters are filled to a height of between 30 to 50 millimetres above the centre of the filter.
Stir the sand in the filter to level the surface.
Remove the tape clocking the airbleed tube and the clean and replace the pipework and airbleed cap. Clean the filter lid and then cover the threads of the lid with vaseline. Replace the filter lid onto the filter.
Open the valves back up and activate the circulating pump with the filter on "Backwash." Pump the water through the filter for three minutes. The water coming from the filter will have a slightly stained appearance. Rinse the sand and backwash for an additional minute. Repeat as needed until the filtered water runs clearly. Reset the valve to "filter" and proceed with filter use as normal.
