    Buy food grade silicon spray and lube the O-rings and sump threads before assembly. If lubed, the O-rings are reusable. You should still have spares. Especially if you don't have a bypass and need to get water back on in the house!

    Marty is correct in everything he says above.

    You'll want to replace this o-ring with every filter change, although merchants who sell the filter cartridges never mention it. Once you remove the old filter for a change, and the existing o-ring pops out (which it will!), you'll never get the old one to re-seat in the groove because it will have deformed and expanded in size.
