When should Filters be backwashed or cleaned?
DE filters are usually torn down and cleaned at least six times per year. Unless your pool gets really dirty, you should not need to backwash it beyond your scheduled maintenance. Another theory recommends to backwash when the pressure gauge is about 8 to 10 psi (pound-force per square inch) over the starting level.
How long do DE filters last?

What should I add to my Hayward pool filter?
After backwashing, new DE must be added to the filter. Add the entire amount of DE the filter recommends. If you see DE returning to the pool, vacuum it to waste, after it settles. The next time you backwash and recoat, decrease the amount by 1 pound. This will avoid DE going back into the pool.

If the handle on the bottom of your Hayward D.E. filter tank is stuck, or broken and you cannot open the valve, well your not alone. This is a common problem.

Once all the DE is added, take a reading of the filter’s pressure gauge. This is the clean starting pressure of the filter. When the pressure rises 8-10 PSI above the starting pressure, it is time to backwash or clean the filter.
