    Pumped or gravity ? I think the seive is gravity?, @Manky Sanke also discusses the NR Valves, their uses and the resistance they generally cause.
    I cant find the link in this app but hopefully this link will get you there.

    I've got an ultrasieve and bead set up I don't have a NR valve however I have ball valves before the sieve and after the bead so that stop flow each way when i turn the pumps off for maintenance
