Hey so if I am correct, for a bean animal overflow the secondary drain is in effect a Durso standpipe. Im guessing there's a special bit to "tap" the cap so I can get a JG fitting on to connect 1/4" tubing?
Here's a pic of the overflow. The center drain is the secondary Durso. At the moment there's no standpipe on the main drain ( it's just the bulkhead on the bottom right of overflow box)
I do have a cap that will go on the top of the Durso. Which is what needs the tubing to be attached to, correct?
