original (clean filter) flow. For example, if the original flow was 60 GPM, the filter should be backwashed when the flow is reduced by about 20 GPM (or 30%) to 40 GPM

2.A more subjective and less accurate indicator is to observe the amount of water flowing from the flow directionals located in the wall of the pool.The filter should be backwashed once it is detected that the flow has been reduced.

3. The most commonly used but less accurate indicator is to backwash when the filter gauge reading increases 10 PSI over the initial(clean filter) reading.
