How to remove a broken pipe thread inside a wall using a 1,500 won tool

It is bound to be perplexing when old, corroded pipe threads break and get stuck inside a wall while replacing a faucet or a bathroom angle valve. Before breaking the wall or calling a professional, there is a way to solve the problem using a 'metal pipe breaker removal tool kit'.

Principles and composition of the metal pipe breaker kit

According to a video from the YouTube channel Jipsuritong, this tool works by inserting it into the pipe, tightening a bolt to expand the gap to grip tightly, and then turning it to pull it out. The product consists of two metal bars, a bolt, and a hex key to transmit force. It can be found by searching for a 'pipe removal set' online, and in the video, it was introduced at a price of approximately 1,500 won per unit.

Looking at the structure of the tool, the two metal bars can be used together. The video explains that the structure is designed so that one can pass through while the other cannot, allowing the gap inside the pipe to be adjusted freely. The user inserts the tool into the threaded part inside the pipe and tightens the bolt to widen the gap. As the bolt is tightened, the rear part of the metal bars expands, strongly pressing against and fixing the inner wall of the pipe embedded in the wall.

Grip with a hex key and turn, or use another tool

In situations where the pipe is firmly stuck and difficult to turn with hand strength alone, the included hex key must be utilized. The video shows the process of inserting the tool into the pipe, tightening the bolt to expand the gap, and then applying force using the hex key. The video explains that the stuck pipe can be removed by gripping it with the hex key and turning it, or by attaching a separate tool to turn it.

This method can be a useful alternative for those performing pipe or water works on-site. Since it is equipment that can be purchased at a low cost, the video conveys that it is not a bad idea to try it once when a problem occurs with a pipe thread on-site. However, since this is just one of several methods that can be attempted when a pipe breaks, it is important to use it according to the situation.
