As dirt accumulates in the swimming pool filter bed, resistance to flow increases, which causes a reduction in water discharge to the pool. When the flow is insufficient for proper water circulation, it is required to clean the pool filter. This process is referred to as backwashing.</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.linerworld.com/pool_info/articles/103/1/What-Is-Backwashing-And-What-Is-Its-Purpose/Page1.html"><DIV>The correct backwash rate for a high-rate sand filter is the same as it was when the pool filter was in the “filter cycle” (15-25 gpm per square foot of the filter area). In rapid-rate sand filters the backwash rate must be between 12-15 gpm per square foot of filter area (which is 4-5 times greater than the average filter rate per square foot).</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/6CE28C2A-E523-4FF4-8435-9ED22A021910/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
