There are three pipes under the sink, a drain pipe, a hot water supply pipe
and a cold water supply pipe. There are different piping materials and
connectivity methods that have been used over the years and are even in use
today.

You don't say what pipes you are talking about nor the piping materials nor
the connectivity used. You need to buy a good book on home repairs such as
the Readers Digest. This will step you through the repair method for what
you have under the sink.

Saying the pipe is metal doesn't help much because different metals use
different methods. You need to learn the piping systems in use and the
terminology. The book is your best bet. Maybe buy two different books to get
two different points of view.

I am not that handy and just moved into a new place. I recenlty
noticed that there was a gap between the wall and sinktop so I lifted
the sinktop to bring it closer to the wall for caulking and
completely forgetting about the plumbing and disconnected the pipe
connected to the faucet. I think the pipes were connected by some kind
of a compound before but when i lifted the sinktop they broke apart.

What's hard now is that the two pipes will hardly align to where the
smaller pipe fits just inside the tip of the bigger pipe. I tried to
put putty around the two pipes and tape around but I can't really get
it tight enough I guess because there is still some leak and the
bottom pipe (smaller) separates from the bigger by gravity.

I also tried a 1-piece connector with screws that I placed between the
two pipes but I got a lot of leak.

Please help!!
