It is fairly easy to remove a filter system from operation, by placing unions disconnects beneath shut off valves, and periodically throughout the system.
The unions allow you to disconnect the system without wresting with the pipes. I place them every couple feet throughout my tank and sumps plumbing.
Below is one just above the pump, to allow removing the pump from service, for easy maintenance.


you can also put shut off valves in different throughout the system to allow sections to be maintained without having to shut the pump off ( I usually run 3 or more tanks to a sump.
