What backwash means
Backwashing is running water backward through a sand or DE pool filter to flush trapped dirt out to waste.
Where it matters on a pool service job
Backwash when the filter pressure rises past its clean reading, not on a fixed day. Write the clean pressure on the filter so every tech uses the same baseline.
