The Backwashing Process
Backwashing is an important process for maintaining a clean and healthy swimming pool. This process involves reversing the flow of water through the pool filter, dislodging any accumulated dirt and debris from the filter media and flushing it out of the system. The backwashing process is typically performed when the pressure gauge on the pool filter reads 8-10 psi higher than the normal operating pressure.
During the backwashing process, the pool pump is turned off, and the multiport valve on the filter is set to the “backwash” position. The pump is then turned on, and water is forced through the filter media in the opposite direction, flushing out any accumulated debris. The backwash process should be continued until the water in the sight glass is clear and free of debris.
Importance of Proper Backwashing
Proper backwashing is essential for maintaining the efficiency of the pool filter and ensuring that the pool water remains clean and clear. If the backwashing process is not performed regularly, the filter media can become clogged with debris, reducing the flow of water through the system and allowing bacteria and other contaminants to build up in the pool water. This can lead to health hazards and other problems.
Over-backwashing can also be a problem. This can lead to excessive water waste, which is not only costly but also bad for the environment. It is important to strike a balance between performing the backwashing process often enough to keep the pool clean and minimizing water waste. It is recommended that pool owners backwash their filter once a week or as needed based on the pressure gauge readings.
Types of Pool Filters
- Sand filters: These are the most common type of pool filters. They use a layer of sand to trap debris and other impurities in the water. Sand filters are relatively easy to maintain and can last for several years with proper care.
- Cartridge filters: These filters use a replaceable cartridge to trap debris and other impurities. They are typically more efficient than sand filters and require less maintenance.
Another type of pool filter is the DE filter, which uses diatomaceous earth to trap impurities. DE filters are highly efficient and can trap particles as small as 2-5 microns, making them the best choice for pool owners with allergies or other respiratory issues. However, they are also the most expensive and require more maintenance than sand or cartridge filters.
Overall, the backwashing process is an essential part of maintaining a clean and healthy swimming pool. By understanding how to properly backwash your pool filter and choosing the right type of pool filter for your needs, you can ensure that your pool remains crystal clear and safe for swimming.
