Backwashing is the process of reversing the flow of water to flush out dirt, dust, and organic debris trapped inside the pool's sand filter. While this procedure is typically done once a week during standard periods, it must be monitored much more carefully and performed more frequently as we approach the end of summer due to the increased filter load.
Factors Straining the Sand Filter at the End of Summer
Your pool operates at maximum capacity throughout the entire summer season. By the time August and September arrive, the main factors increasing your filter's burden include:
- Cosmetics and Body Oils: Sunscreens, tanning oils, and sweat that mix into the water throughout the summer cause the sand grains in the filter to stick together and petrify (calcify).
- High Organic Waste Load: The increased number of swimmers in hot weather leaves more microscopic waste in the water. This waste clogs the filter much faster.
- Increase in TDS (Total Dissolved Solids): As water evaporates, minerals and chemical residues are left behind. Backwashing not only cleans the filter but also allows fresh water to be added to the pool, reducing the water's chemical fatigue (TDS).
- Early Autumn Winds: Dry winds starting at the end of summer carry fine dust, pollen, and early falling leaves into the pool, rapidly increasing the filter pressure.
How Do You Know If the Filter Is Clogged?
The pressure gauge on the filter gives you clear information about the system's health. When the operating pressure of a clean filter is at its standard level, and the gauge needle rises 0.5 to 0.7 bar (7-10 psi) above this standard value, it is definitely time to backwash.
Smart Filtration Infrastructure with Anatolia Pool & Spa
Constantly checking the filter pressure manually and turning backwash valves is a cumbersome process. At Anatolia Pool & Spa, we integrate fully automatic backwash valves into the professional plant rooms we build upon request.
These systems automatically initiate and complete the backwash process without human intervention when the filter pressure rises. Contact us for marvelously engineered pool systems that extend the life of your plumbing and keep your water crystal clear at all times.
