SLAM - What pressure to backwash?

[Kdebelius]

I’m helping my neighbor SLAM a very green 30,000 plaster pool with a Pentair pump and Hayward DE filter. At what pressure should I backwash?

At what pressure should I backwash?

We backwash when the pressure increases by about 25%. So next time you backwash, make note of the new clean pressure reading. Then when it increases by about 25% it's time to clean again.

Thanks, Much appreciated!
