Hi Bruce
Put in a Y or a T made of PVC pipe and a small gate,then you don't need to unplug it just open the gate,you can make a small gate with some 1/4" and 3/4" MDF stock.
Open one Close one quick and easy, or you can use a small trap door type they use for built in vac.systems in a house,they make them to side in to PVC pipe and glue in place. ( Home Depot/Lowe's items)

The ones below are blanks,one side set up for 2 1/2" the other side is still open for any size I need, it can be 1" to 4",just a snapshot to show how to make them out of MDF
