Have a plumber snake out your drains.

ANS 2 - Install a flapper valve section on the sink drain pipe so water can go down but not up - cheap and very easy to do.

Most Likely, your pipes are all hooked up in the same system. all the pipes travel to the basement most likely.

It is quite possible that your main pipe to the city sewer system has become blocked somewhere between the basement floor drain and the man city sewer line. Could be a result of items flushed down the toilet(s), or damaged pipes as a result of age, tree roots searching for water, etc. Suggest having your main access to the city sewer system checked by camera.

partially clogged drain or vent, improperly installed vent or drain

The main line going out is getting clogged or has collapsed.

The water lines are probably not secured properly.The toilet fill valve closes and then water hammer occurs, causing a banging or clanking.

The first American film where a toilet was flushed was "Psycho" in 1960!

There is a main drain that runs from the basement through the roof where it is the vent for the system. If you look at the layout of the house, the upstairs bath is most likely over the downstairs one or the kitchen. If you look on the roof, you will see a 4 inch pipe coming through the roof that should be over the upstairs bath. The sink and shower drain into that and then to the basement and out of the house. Most likely the main stack is in the wall behind the toilet.

There is a blockage in the waste line. Have you flushed the basement toilet to see what happens? Try running the upstairs shower and see what happens. (use two persons , one up stairs, one downstairs so you can control the amount of water that rises in the toilet.) There should be a "clean out" cap somewhere downstairs near the point where the waste line exits the house. It is here that one would "snake" the line. The other possibility is the water level in the downstairs toilet is lower than the level of the waste line exit. This means that the point of exit of the line is physically higher than the toilet. The only remedy for this is to raise the toilet to above the height or replumb the toilet into a waste pump that evacuates upwards to a point slightly higher than the waste line. This is the most common set-up in a "basement" toilet. The toilet evacuates into a point lower than the floor. The waste pump or grinder pump then pumps the waste upwards than gravity allows it to evacuate normally. The benefit is that the waste pump creates a separate system for the basement toilet.

when Anne frank and her family where hiding in the annex who flushed the toilet.

I do not know if popcorn can be flushed down the toilet. So, I wouldn't try it.- Ashton Smith

The downstairs toilet is not properly vented and the flow from the one upstairs creates a vacuum in the waste line.

Depends on if it needed to be flushed or not.

Yes you can flush it. It's possible for a toilet trap to go dry after that much time. When you flush just make sure you check to see if the bowl is leaking.

The gurgling in your kitchen sink drain trap is because your drain system from you upstairs toilet is not vented properly. As the flow drops down the vertical drain pipe from the upstairs it sucks the water out of your kitchen sink drain trap and causes it to gurgle. It could drain the kitchen sink trap and allow sewer gas to flow into your kitchen. The fix is to either install an Air Admittance Valve (AAV) in your kitchen sink drain plumbing or properly vent the upstairs toilet drain.

Try adjusting the stop cock level. How far the stop cock goes up. This should stop it.

Possibly wax ring or toilet tank to toilet bowl gasket.

How can I do some home toilet repair? I have an upstairs pipe that is leaking underneath the toilet.

This dream suggests that something you thought had been "flushed away" has come back in a very big way.

The toilet is the lowest point, fluids seeks the lowest level, other sewage is coming up through your basement toilet. The system might be installed wrong or there is a blockage in some discharge pipes. Call a plumber, it can be really bad, when I was a kid we had our whole basement flooded with two feet of raw sewage after a big rain storm.

Yes, in Australia the toilet flushed counter clockwise.
