Any idea where the copper tube goes? Maybe to save a bucket when washing the floor.– crip659Commented Jan 17, 2022 at 20:28

It runs parallel to the main toilet drain all the way to the basement and out the main. Also where it t's off it doesnt flow down the overflow tube at all. Im scratching my head here none of my other toilets have this– RobfCommented Jan 17, 2022 at 20:39

1It is a weird setup in any sense.– r13Commented Jan 17, 2022 at 20:46

4The only thing I could think(bad idea to do) of, is to keep an old unused P-trap filled with water, or someone had extra copper pipe around and wanted to weird you out.– crip659Commented Jan 17, 2022 at 21:44

1An amoeba ladder, similar to a salmon ladder, to allow the critters to migrate upstream, or it uses refill valve flutter to play very low bass notes through that length of copper tubing -- AKA "sewer flute". as created by PDQ Bach (youtube.com/watch?v=2j5yy9xXMGk).– DrMoishe PippikCommented Jan 18, 2022 at 2:04

It looks to me like your flush system was replaced. The liner (looks like styrofoam) is interesting. The intention there is either to reduce the amount of water per flush or to inhibit condensation on the outside of the tank due to cold water entering. You can see it was roughly cut back to install the flapper. I have absolutely seen in other toilets a small diameter tube going from the ball cock into the overflow pipe. The tee fitting looks old and probably original. Instructions for the replacement say the rubber hose should not terminate below the tank water level or water will continue to flow so I think the leg of the tee going downstairs is a jury-rig way of handling overflow. A big waste of water. The fix? Replace the rubber hose ensuring it ends above the water line and eliminate the copper rigamarole.
