Every pool filter has a backwash setting among other multiport valve settings, which is important in cleaning your filter at least once a week for sand filter and after 3 – 4 weeks for DE filters in order to free the filter of dirt and debris it has collected while filtering your pool water.

If you don’t backwash your pool filter frequently, your filtering media especially Sand and DE agents will be clogged with dirt and debris and will not filter your water turning pool water dirty or cloudy.

我怎么知道我的泳池过滤器需要反冲洗？

There are a few signs that will tell you when it’s time to backwash your pool filter, however, a good swimming pool cleaning practice is to backwash your pool filter at least once a week especially when your fill-water is not very clean. You will know your filter needs backwashing when:

1. 泳池泵噪音很大 
2.  通过回流喷嘴流入水池的水流速度很慢
3. 泵压力表显示的压力比清洁压力或启动正常压力高出 8-10 磅/平方英寸 (psi)。
4. FC 水平正常时，水始终浑浊

如果您发现泳池出现这些迹象，则很有可能是过滤器堵塞了，您需要反冲洗并漂洗几次才能解决这些问题。

We recommend Hayward pool pumps and filters and the following guide will include how to backwash  Hayward DE and Sand filters.

然而，反冲洗的过程与 Pantair 等其他过滤器型号类似，只是压力表水平可能因品牌而异，您可以按照以下指南来帮助您反冲洗不同品牌的过滤器。
