Many times the nuts that hold plastic drain pipes together can become loose. Especially if items are stored under the sink the pipes can be bumped and over time may loosen. Fixing loose plastic drain pipes can be accomplished by even the novice in just a few minutes and with a minimum of tools. Usually there are three pieces in the drain plumbing for a sink. All three should be checked and tightened even if only one appears to be loose.

Examine the drain pipes under the sink and become familiar with the different parts. There should be a straight pipe that comes from the bottom of the drain. The straight pipe connects into a curved pipe called the p-trap. The p-trap generally connects to another straight pipe which goes into the wall. The parts are held together with plastic nuts at each connection point.
Grasp the straight pipe with one set of slip joint pliers and use the other set of slip joint pliers to tighten the nut which connects the straight pipe to the p-trap. Do not over tighten or the threads can become damaged.
Hold the p-trap with one set of slip joint pliers and use the second set of slip joint pliers to tighten the nut that connects the p-trap to the straight pipe that goes into the wall. Again do not over tighten the nut.
Hold the straight pipe that goes into the wall with one set of pliers and with the other set tighten the nut that connects the straight pipe to the plumbing in the wall.
