Many times, once you"re putting the pump/filter system back together, the union"s O-ring will slip the end or autumn out the its groove. And when you litter it off its groove, negative things happen—like letting wait in.

Reminder: when you tighten your union earlier up, make certain that the flange (ridge) is flush with the earlier of the nut. If it"s not, miscellaneous is obstructing the union from totally closing.


The union between the valves and the pump should have its O-ring in the ideal groove, through no damage and no dirt or debris obstructions.
