What should my DE filter pressure be?
The size of your pool, the size of your pump, and the condition of your pool water directly impact pressure readings. Generally speaking, a pressure reading between 10 – 25 psi can be considered normal. Once you have installed a new filter, turn everything on and take a baseline reading.
What should the pressure be on a water filter?
In this case, let’s say normal clean filter pressure runs around 22 PSI. If the gauge is reading 25 or 26 PSI, that just means the filter is doing its job and starting to get dirty. In this scenario, it would need to be 30 to 32 PSI to indicate that it needs to be back-washed. Shut off the pump and position valve to “backwash.”
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 PSI be on a pool filter?
For most filters, 20 or 30 PSI is considered too high, but you should consult your pool professional to make sure that’s true for your model. If you’ve cleaned the filter recently and you’re still showing an above-normal PSI, check for leaks in your filter system.
What should the pressure be on a Hayward pool filter?
Hello JohnGarrity – The pressure does usually rise slightly after adding DE. 4.5 pounds of DE would be correct for the Hayward DE3620. As far as the starting PSI, every pool is different. A starting PSI of 15.5 is not unusually high. It sounds like the filter is working properly.
