My Braided Flexible Tube Hose Is Leaking

Flexible hosing provided an easy fix for the common plumbing connections in bathrooms and kitchens, where metal pipes used to be the common material. Instead of having to learn how to solder pipes together to make a watertight connection, plumbers simply screw the braided flexible tubing to the pipes with the help of an adapter. However, since these new pipes are not nearly as tough as the old pipes, they have their limitations.

PSI Ratings

When you install plumbing products for your water needs, be sure to check the psi (pressure per square inch) ratings for the tubing you plan to use. Typical water pressure in residential neighborhoods with municipal water tends to run between 40 and 70 psi. However if you live in an area much lower in elevation than the water tower, the pressure is much higher. You may have to install a pressure regulator to save the plumbing connections in your home from springing leaks.

Connections

Check the braided flexible tube to see where the water is coming from. Typically, the connection is the source for the leaks. When you screw the braided flexible tube onto another connection, you need to remember to include thread seal tape around the threads for a watertight fit. In high-traffic plumbing, you may want to consider using braided steel tubing, which will withstand more pressure drops and surges.

Replacement

Since the braided flexible tubing is readily available, inexpensive and easy to install, the easiest way to fix a leak is to replace the tubing. Make sure you turn off the water supply and leave a towel on the floor to catch any drips, then take the old hose to the hardware store to replace it with a new one. Installing the new one is as easy as winding some thread seal tape around the threads and screwing the braided flexible tubing onto the fitting or connection.

Distance

Before you replace the old section of tubing, check to make sure that the old tubing was not too short. When you measure the distance between the inlet valve and the fixture that the tubing needs to cover, add 4 inches to make sure there is no tension on the line. If you notice the old tubing is shorter, you'll know there was excess tension pulling the connection apart.
