We recently bought a house with a pool (I think pool is about 4 years old). This is my first pool so forgive my ignorance and lack of the proper technical terms. I recently opened the Hayward cartridge filter container and cleaned out the filter using a hose. I put it back together just as it came apart, tightened the rings, etc, but now the pressure won't go back up to where it was (around 20-25 psi) and the pump never becomes fully pressurized in the visible area where the pump basket is. However, when the I run the spa filter, it seems to pressurize just fine. I've opened the air release value and while water squirts out it makes no appreciable difference in the pressure. Do I have air in the line or maybe debris or did I fail to do something when putting the cartridge back together??
Cleaned filter and now pressure is low. What did I do wrong?

A cleand filter SHOULD show lower pressure on your gauge cause it is getting better water flow now. Dirty filters produce higher pressures or "resistance".

Welcome to tfp, seifert1427
How is the flow at the pool return? What does your pressure gauge read when the pump is off? What pump and filter do you have? Is there air in your pump's leaf basket when the pump is running?
Ideally sized cartridge filters tend to run much lower than 25 psi. It could be that your filter needed cleaning a long time ago, and now that it is clean it is running at a much lower pressure. We recommend cleaning when the pressure goes up 25% from the clean pressure.

My clean filter runs about 20 PSI and dirty runs close to 30. What is yours running now? Also when I run in spa mode my runs higher.

My filter was running around 25-30 but now it won't register above 3-4. Clearly there is something wrong. The system doesn't seem to be coming up to full strength. In the pump basket area, before the water would eventually fill the entire space creating a vacuum. Now, water is continually flowing through that space and never fully pressurizing. So it appears that there is air in the pump leaf basket area but again, only when the pool pump runs. With the spa pump, there is no issue.

Very low pressure indicates you either have something blocking the system BETWEEN THE PUMP AND THE SKIMMER or you have an air leak in that same area.
A clogged impeller is another possibility but not quite as likely. Remove the pump basket lid and put your hand into the impeller to see if you can feel any debris stuck in there
Check the pump basket lid....it's the most common place for air leaks.

My guess would be that water is bypassing your filter cartridge. Double check that it is fully seated and has no tears in it.
