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.
Which is worse low or high pool filter pressure?
Low pressure in your filter is much less dangerous than high pressure, but it means your filter isn’t doing its job. Low pressure will (almost) always be caused by a problem at or before the pump. That’s because after the pump the water is under pressure so any problems would produce high pressure, not low.
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 I do if my pool filter is not working?
The only regular maintenance is to clean out the filter periodically when it has captured so much debris that water isn’t flowing properly. If you have a cartridge filter, you can take out the cartridge and clean it. If you have a DE filter, you can remove the filter, wash it off, and then replace the DE.

Why does my filter have a high psi?
A filter pressure gauge is used to measure a filter’s PSI and every filter should be equipped with one. The most obvious reason for high PSI is that the filter is dirty. Simply cleaning the filter or backwashing it if you have a D.E.
