Hi, hopefully someone can help me here. I have a basic inground pool. It has a 3/4hp pump, only 2 years old. It has a 75sqft Hayward cartridge filter. Recently, the pressure is down to about 3 PSI. When I look into the basket area attached to the pump, it doesnt seem to be drawing tons of water in like it should. When I use the bleeder valve to remove the air, it takes a long time to get up to the top...water is not filling the cartridge. That has had no effect. The filter itself is less than a year old and pretty clean. When I run the system without any filter, it drops to less than 2 PSI, so I do not think it is the filter. So, I naturally suspect the pump, but it is new and I had it looked at 6 months ago by a pump service company (for another issue) and they gave it a clean bill of health. I do not seem to be leaking water anywhere in the system. I do not seem to be adding more water that usual so I do not suspect an underground leak. Any ideas?
