Have a Haywood 4 cartridge system. There is an outlet on side of pool below water surface to the polaris pool cleaner. This hose has a fine screen to trap debris so it does not harm the polaris.
The debris getting past the cartridge filters is so bad, that I must clean the screen daily, else the water pressure drops off enough that the polaris does not run.
I clean the cartridges faithfully and examine them for any tears or holes... there are none. The system is plumbed correctly.
Is there anything that can be done to prevent so much debris from getting around the cartridge filters?
