On our new construction projects, it is common to backwash weekly when there is a lot of dirt and debris flying around.
If you are using a separation tank for backwashing, or a separate tank that separates the DE from the waste water, and returns clean water to the pool (prevents water wasting) - it is especially recommended to bump the filter as described above, and run your backwash cycle for a longer time period, maybe 10 minutes.hen backwashing a D.E. filter, bump the filter several times. That is, backwash until water runs clear, move the multiport valve to FILTER and run it on filter for a 5 - 10 seconds, and backwash again until it runs clear, etc...do this 2 - 4 times.
