If the leak is occurring at one of the joints between pipes, try tightening the slip nuts. On a metal trap, tighten them hand tight plus about a half turn, using slip-joint pliers to grip the nut. On a plastic trap, just hand tighten, and, if needed, give the nut about a quarter of a turn with slip-joint pliers.
How do you stop a compression joint leak?
Tighten compression fittings firmly with two wrenches to crimp the ferrule onto the pipe (Photo 3). Also make sure the pipe or tube goes straight into the fitting. Misalignment will cause a leak. If the fitting leaks after you turn on the water, try tightening the nut an additional one-quarter turn.
How do you fix a leaky drain trap?

Can you over tighten compression fittings?
The tubing will bulge and stick inside of the fitting if the ferrules are overly secure. If you can’t disassemble the valve or fitting, it’s a good indicator that the connection is much too tight. The only thing to do in this instance is to remove and replace the fitting in question.
Should I use thread sealant on compression fittings?

Should you use PTFE on compression joints?

Can too much Teflon tape cause leaks?
Its physical composition allows it to fill pipe threads and fitting threads with a sealant that will prevent water from leaking through the thread connection. However, the biggest problem with Teflon tape is that if it is not applied correctly to plumbing threads, then the fittings could leak.
