I found this in a home built in 1950. The “can” is a component of the sanitary sewer. 2" cast-iron inlet from the bathtub drain connected to the bottom of the can; 2" C.I. outlet at top of can ties into 2-1/2" C.I. pipe then 4" C.I. to main sewer. The can is 4" diameter and 5-1/2" tall. As you can see, it’s rusted pretty badly and leaking from the top of the can.
What is this “can” and what is its purpose?
Repair is unlikely due to the extensive rust. So replacement is necessary. Is this component still available today? If not, can it be replaced with a standard P-trap…or what?
Any help is appreciated.
