How can you tell if your system is plumbed backwards?
Peel back the broken top and examine the pleats. Is there dirt accumulation on the inside of the pleat pack?
Does the support band on the outside of the cartridge, if present, appear stretched and wrinkled?
Do the outside of the pleats appear rounded and puffy?
If you are still not sure if your filter is plumbed backwards, shut down the entire system and completely bleed the canister pressure. Remove the cartridge and with the lid off quickly turn the pump on and off. Observe which port is delivering the feed water and assure that it is the "inlet." (Always consult the manufacturer's instructions before removing the canister lid or working on any pressurized system.)
