What Causes the Leaking of Braided Plumbing Lines?

Braided Plumbing1A braided plumbing line connects a supply valve to a plumbing fixture, like a tap. The word BRAIDED is in reference to the exterior covering of the pipe, a flexible woven metal sheet. Leaks can happen at numerous sections of this kind of plumbing line, often due to deterioration, prolonged stretching, or punctures. If you know how to find out what caused the leak in the braided line, you can determine if it has to be fixed or replaced.

Cracked Threads and Loose Nuts
Braided plumbing lines are attached to valve outlets and tap inlets through threaded nuts. A washer that is behind every nut compresses against either the inlet or outlet so a watertight seal is formed. A nut that is loose permits the seeping of water around the washer and allows it to leak at the section between the threads and the nut. A nut excessively tightened, on the other hand, may crack threads and also cause water to leak out. Plumbers, in general, tighten the compression nuts of braided lines at approximately a quarter-rotation beyond hand-tight.

Thread Sealant
The compression threads of braided lines have a design that is different from the usual pipe threads. While the common pipe threads need a coating of thread sealant so a watertight seal can be created, the compression threads of braided lines create a good, watertight seal with the plastic washers that come with them. When this is applied to a compression thread, sealant may spread or jam a thread. If there is sealant on the threads of the braided line, take the nuts out, and then clean off sealant from the tap or valve inlet as well as the braided line.

Crimp Collar
The nuts of the supply line connect to the assembly hose or body via a crimped collar. The makers usually smash this thin cylindrical metal piece around the end of the hose so that the nut is firmly attached to the assembly of the supply line. Any leaks located at the joint in between the hose and the crimped collar usually are an indication that the collar is suffering from a break, a crack, or corrosion. Braided lines with leaky collars generally have to be replaced.

Hose Breaks and Punctures
Tough steel may have been used to create braided plumbing lines, but they are still prone to cracking and puncturing. Often, excessive twisting can cause them to crack. Fortunately, they can be prevented by taking the braided line out during a repair instead of forcing it aside. Many objects can puncture braided lines, like sharp tools, nails, and screws. Generally, any cracked or punctured hose should be replaced.
