Hi, I just replaced the cartridges on in my pool filter and still the pressure did not go down. The pressure had gone up to about 33-34 psi so I tried to clean the cartridges but they looked in need of replacement so I bought 4 new cartrdiges and put them in. Turned the pump back on and the pressure was still the same around 33-34 psi. Then I cleaned out the filter for the pop-ups and the pressure did fall down to about 24 to 25 but its still much higher than 18 psi which was the pressure when I moved into this house.
Also, the pressure does seem to fluctuate - it will run at about 24-25 most of the time but then it will suddenly fall to ~20 for 15-20 seconds then go back up to 24-25. Not sure if this is normal because I think it used to be like that even more the cartridge replacement. Just assumed it happens when one set of popups is going down and the other is coming up.
Only other difference I have noticed is that the pump is making a bit louder rattling noise than normal. Especially as compared to the second pump i have that powers the water features.
Any help will be greatly appreciated. Thanks, ap
