The Right Way of Fixing Pinhole-Sized Leaks in Your House’s Plumbing System
A pinhole-sized leak usually goes undetected until water damage has occurred to a part of your home. This possibility is the reason why you should check water-damaged parts of your home right away. If you do find out that the damage was due to a pinhole-sized leak in the plumbing, the best solution is soldering a coupling on the part where the leak is located. Below are the steps you need to follow so it is done correctly, and you can do them yourself without the need for a plumber.
1. Switch the water supply leading to the pipe that needs to be worked on. This means switching off water to an entire section of your home or switching off water to your property. Once you have switched the water off, position the business end of the pipe cutter on the pinhole-sized leak. Then tighten the cutter and twist it so it slices through the pipe wall. On occasion, tighten the cutter further so that it cuts deeper into the wall of the broken pipe. Twist the cutter until you have severed the pipe.
2. Put a bucket under the pipe and let water drain down it. Once water slows down to a drip, get a rag and wipe the pipe surface with it.
3. Get emery cloth and rub it on both cut portions of the pipe as well as both interior parts of the coupling so any grit, oils, and corrosion are removed. Apply a coat of flux to the interior of the two sides of the fitting and the pipe ends using a flux brush.
4. Gently pull a cut portion of the pipe to your direction. Carefully slip the coupling to the pipe, and then push back the pipe to original position and install the coupling to the adjacent pipe by sliding it in. Make sure to slide the coupling so it is positioned evenly between pipes.
5. Get your plumbing torch and light it. Hold it against the rear portion of a side of the coupling. Press the solder against that part of the pipe you are heating, and once it melts on the pipe, take the torch away and press the solder to the joint located between the pipe and the coupling. Let solder flow to the joint until it squeezes from its rim. Wipe excess solder using a wet rag.
6. The torch should then be moved to the opposite portion of the coupling. Get the joint hot, apply solder, and then wipe away the excess using a wet rag.
