It is important to regularly check your pool filters. The debris, containments, and particles can be trapped within the filters which can prevent them from entering the pool water.
Different types of Pool filters
Cartridge Pool filters
Cartridge Pool filters are ideal for spas, and small above ground pools. This filter can trap dirt and particles up to 10- 100 microns. When your canister reaches 8-10 pounds above normal, it’s time for a cleaning; a simple garden hose can do the trick. Just rinse out all the dirt and debris from top to bottom. Once the Cartridge Pool filter is clean, it’s ready to be used again.
Common Problems with the Cartridge Pool Filters and how to fix them
There is the chance that the clamp band may spin off, but this is very simple to fix and no tools are required. You will notice this when the o-ring is flattened or water is dripping from the filter. It’s important to clean and lubricate the O-ring annually, and always make sure the lid is secured afterwards.
DE Pool Filters
The De Pool Filters are the most widely used pool filters on the market as of now. It can trap particles up to 3-5 microns; a measurement that is well below the naked eye. When the pressure gauge read 8-10 lbs above the normal filter pressure, it’s time to backwash the filter. This process involves turning a valve so water will flow through the filter backwards, while flushing out dirt and other debris. After the backwash, a DE powder is added back into the filter.
Common Problems with the DE Pool Filters and how to fix them
Many DE Pool Filters have belly band clamps with a large O-ring in between the tank halves. There is a chance that the o-ring can become flattened and will need to be replaced if water is dripping from the clamps. If the DE filter is leaking back into the pool, internal filter repair is required.
Sand Pool Filters
The Sand Pool Filter is specially made to trap particles up to 20-100 microns. As the filter traps more dirt, the more efficient it will become. Like the DE Pool Filters, once the Sand Pool Filter reaches 8-10lbs above the normal filter pressure, it’s time to backwash the filter. The Sand Pool Filters are known for the lowest maintenance of the three pool filters. In fact, you may only have to open up your pool filter every 5 years.
Common Problems with the Sand Pool Filters and how to fix them
Sand Pool Filters hardly leak, but when they do it is likely from the multiport interface. Sadly there are no safe, effective ways to patch a Sand Pool Filter, so when there is a crack or a hole in the filter, it’s time for a replacement. With no problems, a Sand Pool filter can last up to 20-25 years.
