Sand vs Cartridge Pool Fiters
Sand and cartridge filters are two different types of filters that are commonly used in pool filtration systems. Both types of filters are designed to remove debris and contaminants from the water in a pool, but they have some important differences in terms of their design and function.
Sand filters are the most common type of filter used in pools. They use a layer of sand to trap debris and contaminants in the water. Water flows through the sand, and the debris and contaminants become trapped in the sand, allowing clean water to pass through. Sand filters are relatively low maintenance and can be effective at removing debris and contaminants from pool water.
Cartridge filters are a more advanced type of filter that use a pleated cartridge to trap debris and contaminants. Water flows through the cartridge, and the pleats in the cartridge trap the debris and contaminants, allowing clean water to pass through. Cartridge filters are more efficient than sand filters and can trap smaller particles, but they require more frequent cleaning and maintenance.
Overall, the main difference between sand and cartridge filters is the type of media used to trap debris and contaminants. Sand filters use sand, while cartridge filters use a pleated cartridge. Sand filters are lower maintenance and can be effective at removing larger debris, while cartridge filters are more efficient and can trap smaller particles, but require more frequent cleaning and maintenance.
Required maintenance for each type of filter
The required maintenance for sand and cartridge filters will vary depending on factors such as the size of the pool, the type of filter, and the amount of use the filter receives. However, there are some general maintenance tasks that are common to both types of filters.
For sand filters, regular maintenance tasks include backwashing the filter to remove accumulated debris, checking and replacing the sand when needed, and cleaning the filter valve and other components. Sand filters should be backwashed every one to two weeks, and the sand should be replaced every three to five years, depending on the type of sand used and the amount of use the filter receives.
For cartridge filters, regular maintenance tasks include cleaning the cartridge to remove accumulated debris, checking and replacing the cartridge when needed, and cleaning the filter valve and other components. Cartridge filters should be cleaned every one to two weeks, and the cartridge should be replaced every one to two years, depending on the type of cartridge used and the amount of use the filter receives.
In addition to these regular maintenance tasks, it is also important to perform periodic inspections of the filter system to ensure that all components are functioning properly and to identify any potential problems before they become serious. This can help to extend the life of the filter and ensure that it continues to operate efficiently.
How to tell when to clean the filters
There are a few signs that you can look for to tell when it is time to clean your pool filter. One common sign is a decrease in water flow through the filter. This can happen when the filter is clogged with debris and contaminants, and it can cause the pump to work harder to move water through the filter. If you notice a decrease in water flow, it may be time to clean the filter.
Another sign that the filter needs cleaning is an increase in the pressure reading on the filter gauge. As the filter collects debris and contaminants, the resistance to water flow increases, which can cause the pressure reading on the gauge to rise. If the pressure reading on the gauge is higher than normal, it may be time to clean the filter.
Additionally, if you notice that the water in your pool is cloudy or has a strong odor, this can also be a sign that the filter needs cleaning. Debris and contaminants in the water can cause these issues, and cleaning the filter can help to remove them and improve the water quality.
In general, it is a good idea to clean your pool filter every one to two weeks, or more frequently if you notice any of the signs mentioned above. This will help to keep the filter operating efficiently and ensure that the water in your pool remains clean and clear.
How to clean a cartridge filter
To clean a cartridge filter, you will need to follow these steps:
- Turn off the pump and relieve the pressure in the filter by opening the air relief valve or pressing the air relief button, if your filter has one.
- Remove the cartridge from the filter housing by opening the housing lid and carefully lifting the cartridge out.
- Rinse the cartridge with a hose to remove any loose debris and contaminants.
- Soak the cartridge in a solution of filter cleaner and water according to the manufacturer’s instructions. This will help to loosen any stubborn debris and contaminants that are stuck to the cartridge.
- After soaking the cartridge, use a soft-bristled brush to scrub any remaining debris and contaminants from the cartridge. Be sure to scrub the pleats and the end caps thoroughly.
- Rinse the cartridge with clean water to remove any remaining debris and contaminants.
- Allow the cartridge to air dry completely before reinstalling it in the filter housing.
- Once the cartridge is dry, reinstall it in the filter housing and close the lid.
- Turn the pump back on and check for any leaks or other issues.
It is important to follow these steps carefully to ensure that the cartridge is cleaned properly and to avoid damaging the cartridge or the filter housing. If you are unsure about how to clean your cartridge filter, it is best to consult the manufacturer’s instructions or contact a professional for assistance.
How to clean a sand filter
To clean a sand filter, you will need to follow these steps:
- Turn off the pump and relieve the pressure in the filter by opening the air relief valve or pressing the air relief button, if your filter has one.
- Remove the filter lid and locate the filter control valve. This is typically a large valve on the side of the filter housing.
- Set the filter control valve to the “backwash” position. This will cause the water to flow in reverse through the filter, flushing out the accumulated debris and contaminants.
- Start the pump and allow the water to flow in reverse for several minutes.
- Stop the pump and set the filter control valve to the “rinse” position. This will cause the water to flow in the normal direction, rinsing out any remaining debris and contaminants.
- Start the pump and allow the water to flow in the normal direction for several minutes.
- Stop the pump and set the filter control valve to the “filter” position. This will return the filter to its normal operating mode.
- Check the filter for any leaks or other issues and make any necessary repairs.
It is important to follow these steps carefully to ensure that the sand filter is cleaned properly and to avoid damaging the filter or the filter housing. If you are unsure about how to clean your sand filter, it is best to consult the manufacturer’s instructions or contact a professional for assistance.
Common problems
Leaks around middle band
If your filter is leaking in the middle, there are a few possible reasons for this. One common cause is a faulty O-ring or gasket. O-rings and gaskets are used to create a seal between the various components of the filter, and if they are damaged or worn, they can cause leaks.
Another potential cause of a leak in the middle of the filter is a crack or hole in the filter housing. The filter housing is the outer casing that holds the filter media and other components, and if it is damaged, it can cause leaks.
Additionally, if the filter is not properly assembled or if the components are not tightened properly, this can also cause leaks. It is important to carefully follow the manufacturer’s instructions when assembling and maintaining your filter to avoid potential leaks.
If you are unsure about why your filter is leaking in the middle, it is best to shut off the pump and contact a professional for further assistance. They can inspect the filter and diagnose the cause of the leak, and provide recommendations for repairs or replacements as needed.
Stack o-ring is loose and can fall off
Hayward brand swimming pool cartridge filters have an issue that can cause problems if it is not resolved. There is a 2-inch stand pipe in the filter that has an o-ring on the top. This o-ring can come loose and allow dirty water to pass around the filters and through the system. At Splash Doctor we recommend changing this o-ring out for a 1 7/8 inch outer diameter o-ring to prevent this from happening.
