Tips for Stopping Plumbing Leaks

There are several options for stopping plumbing leaks. Small water leakages at soldered joints along copper pipes are often easy to fix.

However, they might be a bit challenging to fix in some cases. Read on through this article to know what you should do if everything else fails.

Here are the plumbing supplies you’ll need for the project:

  • Slip joint type of pliers
  • Plumber’s tape
  • Soldering torch
  • Rags
  • Tube cutter
  • Flux
  • Copper fittings
  • Cloth sandpaper
  • Copper pipe
  • Solder (lead-free)

Once you gather the above tools and materials, follow these tips:

Tip #1- Drain the pipe and solder the joint

First, turn off the main water valve. Then open all the nearby faucets. Doing so will drain water from the pipe you’re repairing. Once done, dry the exterior part of the joint. Then sand it with a 120-grit sandpaper.

Sanding the joint will remove any surface corrosion. Next, apply the soldering flux on the joint. Then apply heat using a soldering torch to make the older solder melt.

Once done, apply new solder on the joint. Allow the pipe to cool for at least five minutes. Now turn on the water supply and check whether the leak has stopped.


Tip #2- What to do when the leak doesn’t stop

If the leakage fails to stop, shut off the main water valve again. Open all the faucets to completely drain the pipe.

Remove the entire joint by cutting it off. Get a new joint and solder it in place. Then turn on the water and check whether the leakage has stopped.


Tip #3- Last option when everything else doesn’t work

If you solder a new fitting but it ends up dripping, then you need to try another trick. If you’re working on an elbow joint, you can replace it with a new tee. Solder one end of the threaded fitting to allow moisture escape in the form of steam.

Then heat the pipe joint until the solder melts. Allow it to cool and attach a threaded type of plug. Use pipe compound or Teflon tape on the plug to create a watertight seal.
