I got my bestway above ground pool set up and running for probably a month now and it has the sand filter and pump. I t shows high around 5 1/2-6 psi and isn't supposed to be over 4 1/2 psi. I called and talked to customer service and they said to backwash the system and if that didn't work to take some sand out and try that and I did but still high. Anyone else have any suggestions or had this problem. Thanks
