I will hard plumb my Hayward Perflex EC50 filter and Hayward 1.5hp Power-Flo LX pump. Can you please let me know what I need to connect the PVC piping to motor,filter ,skimmer and pool outlet? Are all the threaded connectors available at local supply store? In the filter manual it says that all the plumbing connections are 1-1/2" NPT. Does it mean I just go to the store and buy 1-1/2" PVC connectors?
