How to Attain a Filter in a Swimming Pool

The pool filter is the heart of your swimming hole. If it’s working correctly, the water stays clean and crystal clear. To maintain the filter operating at its optimum, you need to replace the filter media. Your system will likely fall into one of three classes: sand, diatomaceous earth (DE) or capsule.

Replacing a Filter Cartridge

If your filter program uses cartridges, then you will have to replace it approximately every two weeks, normally. Put a stopper at the consumption and return ports on the pool before opening the filter. The plugs stop the gravity flow of water to the filter at the same time you switch the filter cartridge. Unscrew the cover of the cartridge chamber. Remove the used cartridge. Put in a new cartridge. Replace the cover and tighten the screw. Remove the stoppers from the consumption and return vents. If available in your own filter model, open the air release valve until water flows through.

Replacing Filter Sand

Replace filter mud every three to five years to maintain your body operating at optimum. Plug the intakes in an above-ground pool to keep the water from flowing into the filter program. Broadly speaking, filter systems are placed over the water level of in-ground pools, so plugs aren’t necessary. Open the filter drain valve to remove all of the water from the filter cylinder. Scoop the mud from the filter cylinder. If the opening is narrow, then use a wet/dry vacuum to lift out the sand. Inspect the inner areas of the filter program, such as the standpipe and laterals, if so equipped. Replace broken or worn parts before filling with mud. Consult the manufacturer’s recommendations for the correct quantity of mud for your system.

Replacing Diatomaceous Earth

Replace diatomaceous earth (DE) with every filter backwash. When you observe the pressure gauge reading 10 psi higher than normal, it’s time to flush the system of dirt and debris built up inside the filter unit, which will get rid of the DE too. Close off the electric pump. Move the pump handle down slowly, then up briskly eight times. Close the consumption and return valves. Open the filter drain to permit built up dirt, debris and used DE to flow out of the machine. Shut the filter drain and start the intake and return valves. Turn on the pump. Add the quantity of DE according to the manufacturer’s directions, through the consumption skimmer.

Safety First

Unplug or disconnect the power going to the pump before replacing the filter media. Turning off the power removes the probability of an electric shock. Also, in the event the pump turns on with no water from the machine, the engine can burn, resulting in a costly repair. Use caution when opening a mud or DE filter. A buildup of pressure inside the filter cylinder can lead to an explosion of water and filter media. Maintain your face protected and wear goggles.
