subject: How To Repair A Leaky Drain [print this page] Though many companies are available that are able to help stop the unusual flooding caused by a drain leak, the proper equipment and a can-do attitude can lead to a simple fix executed by the home-owner him/herself. In this article, we will outline the basics of plumbing in regard to a drain leak repair.
The fault area can be discovered by checking the pipe connections. Most commonly, the reason for the leak lies with loosely tightened screws where the P-trap connects to the body. Other reasons include broken parts, cracked seals, blockage, etc.
For this particular job you will need a joint compound, drainage system manual (look online), and a wrench.
To begin, you will need to confirm the location of the leak itself. Start by checking the drainage area. Diagnose the area for broken joints or snapped pipes. Once you have located the correct source, the repair can begin.
Turn off the water supply to stop the flow to the drain being careful to avoid getting wet from any dripping water which may have become stagnant.
Next, you will need to check the pipes. With your wrench, unscrew the nut and inspect for cracks both on the interior and exterior of the pipe. You may also want to check the threads as they can break down over time.
Depending on what you find, you may need to replace one or more parts. In the case that it was the threads, simply replace the nuts, sliding from the tail side. Likewise, if you have found the pipes to be the cause of the problem, then the pipes corresponding to the leaking section would require replacement.
Once you've acquired your replacement parts, it's time to install them! The new joints should be connected and adjusted in a way so that there are no bends which may block the flow of water. Be sure to tighten all nuts properly, adding joint compound if needed.
Now that everything is put back together, restart the water supply and watch over the repaired area noting any leaks. It is recommended to add water pressure slowly to avoid any breaks in case the problem has not been fixed properly. However, if you've inspected the job and found the issue resolved, you've done it!
Plumbing is not for everyone, and it is important not to let pride get in the way of a good job. If you feel as though you gotten yourself in too deep, it just may be time to call a professional.
