Hair can be flushed down a toilet, but only a small amount at a time, otherwise you risk clogging the pipes.
This is water hammer and is caused by rattling pipes that are not secured down properly
it might cause an explosion or it might cause an oxidation and the rust of pipes.
If it is at freezing temperature, then you have an issue with uninsulated pipes.
I do not know if popcorn can be flushed down the toilet. So, I wouldn't try it.- Ashton Smith
The sewer
Depends on if it needed to be flushed or not.
There is an air pocket in one of your pipes, or you could have a small clog. I had the same problem and live in Canada so I got Roto Rooter up to clean out my pipes. It didn't cost that much.
havent you every seen flushed away? the sing and dance and put barbie doll clothes on and go down your toilet and come back up.
Bad venting
Water and waste
Everything is possible but most likely if it was flushed then it will not get caught in the pipes. ------------ Depending on what you are flushing, it can most certainly get caught in the pipes. Older plumbing cannot handle "modern" things people flush down the toilet, such as feminine hygiene products. These can get caught up in the plumbing, slowly building up and eventually blocking the pipe, creating an UGLY mess. If you take a look at most sit-down commodes you will notice that there are a couple of really sharp turns before the system even enters the floor. At these turns, certain hard things like glasses and cell phones can get caught in the toilet itself.
