I flushed my toilet and it overflowed and I couldn't get a towel in time and now there is water leaking into the basement through a big silver pipe that I think is the air/heater pipe, and leaking out of a small copper pipe. I have buckets underneath but I don't know what to do. Its 4:11 am and my dad is sleeping and has to get up for work in 3 hours... What do I do? Any ideas?

I think he would have appreciated knowing the extent of the problem so he could have done some damage control. Sorry, a quick fix here is not possible. We are all volunteers so a plumber would probably not have been available.

It is still overflowing, or it overflowed and stopped as the usual case?
Did you use a plunger?
Water may seem to be coming out of the copper pipe, but it may just be dripping along it, and if it's in the air duct, that shouldn't be a problem unless it works it's way back to the furnace flame and wiring.

Was the water flowing into a floor heater register? Probably fixed now but be careful what you flush-especially at 4AM.

Yeah it was dripping from the heat register in the floor, but it didn't actually get to the vent in the bathroom where the heat comes out of, it seems to have seeped through the floor / baseboards or something.

It stopped finnally. There wasn't that much water but I'm worried its going to get moldy or something between the floors.

That's entirely possible since the plate is usually cut at the floor boot. Were you able to get the toilet to flush? Brian
