My 22" Sand Dollar filter is constantly on 18 psi. I can backwash it for 10 minutes and once I switch it back to filter it is still at 18psi. Why would this be happening?

Unless it has previously operated at a lower pressure, there's nothing wrong. Most pools are in that range for normal pressure.
