Question:

I have 1 20,000 gal with a 1 hp motor how long should it take to turn the water & what should the pressure be?


Answer:

Both questions of how long the water should take to turn over as well as what the pressure should be depends on the type of filter you have. In general, the water should take between 8 and 12 hours to turn over. Concerning pressure, it is hard to tell you exactly what the pressure should be. However, the lower the better. Once your pressure rises about 10 psi above the starting pressure, it is time to backwash or replace the media.
