What should the pressure of a filter be?
A 10 PSI rise over a 10 PSI clean filter pressure is a doubling in return head loss which can dead head a pump. This is why one should use a relative rise (percentage) for determining when to clean a filter. On this forum, we have established a rise of 25% as reasonable filter rise for determining when to clean a filter.
What should my filter pressure be when I backwash?
As the pressure increases, filter (s) are becoming dirty. Usually a 10 psi increase indicates time to clean. So I should assume that the 14 PSI is my normal “clean” pressure, and then I should clean/backwash when I hit about 24 psi?? Just to keep things in perspective, a 10 PSI rise is 23 feet of additional head loss.
What should the pressure be on a sand filter?
As long as the PSI is no more than 10 PSI above the ideal, you don’t have to do much. But when the PSI reaches 10 or more PSI over your ideal, it’s time to clean the filter. Pull out the cartridge to clean it, or backwash a DE or sand filter. If the pressure goes back to the ideal, you’re done.
What should the static pressure rise be for cleaning a filter?
They get a few things right in that article but are still using the old and out dated rule of thumb of a static pressure rise for cleaning a filter which is a mistake. A 10 PSI rise over a 10 PSI clean filter pressure is a doubling in return head loss which can dead head a pump.
What should the pressure of a water filter be?
Your filter may be clean and normal at 9-10 psi, but your neighbor’s filter gauge could run higher, and be clean at 15-16 psi. Some systems with very low resistance can run very low pressures, barely registering, while other filter systems can run quite high, pushing 30 psi when the filter becomes dirty.
What should the pressure be on a de filter?
The pressure on the DE filter is starting out normal and rising to 30 psi within an hour. When the filter is shut off, it goes back to normal then takes an hour to rise again. I know nothing about DE filters but it sounds to me like this is a mechanical issue. Jeff said he cleaned the DE filter.

When does the pressure on the de filter go back to normal?
The pressure on the DE filter is starting out normal and rising to 30 psi within an hour. When the filter is shut off, it goes back to normal then takes an hour to rise again.
What should my filter pressure be after a clean?
The previous “normal” PSI was around 12. Now with the newly installed pump (1HP Max-Flo), the average PSI after a clean etc is around 18. I would assume this is a good thing since that means greater flow/turnover, correct?
What does it mean when your filter pressure goes up?
Higher flow rates cost $$ in energy. Second question from reading previous posts, a decrease in pressure means it’s time to clean/backwash etc. but what about an increase? Would there be a natural situation that would move the PSI up? Click to expand… An increase in pressure (filter pressure gauge) means it is time to clean.
What should the pressure be on a pool filter?
If anything could be considered “normal”, it would be about 10 psi. Most filter systems are designed to operate in the 5-15 or 10-20 psi range. The way to find out your particular correct pool filter pressure is to clean or backwash the filter thoroughly and empty the pump and skimmer baskets.
