I just noticed that the filter after venting the air has a very low pressure, Water/air used to come out at high pressure/volume and now is barely trickling torugh teh manual air relief valve.
Opened the filter to change the cartridge and same thing the air would barely get in to equalize, I had to open the drain to be able to remove the top cover/bell.
After installing the new filters and cleaning the inside , the filter has the same low pressure. The pressure indicated is 12 bar, usually is aboud 14-15 with new filter, and same as before the cartridge exchnage the water is just trickling now high flow on the manual air relief.
What can cause this ? The rest of the punpoing system seems to work fine, I hand checked the pressure getting into the pool and seems normal.
Thanks in advance for any suggestions.
