How Often Should You Replace Them?

If you’ve ever had a bathroom leak or a flooded bathroom, it was most likely due to supply line damage. Supply lines connect fixtures like sinks or toilets to your home’s main clean water line. Most bathrooms have at least three supply lines: one to the toilet and two to the sink (one for hot water and one for cold water). Keeping your supply lines in good shape is key to avoiding costly water damage cleanup in your bathroom. How often to replace them depends on the type of line.

1. Non-Braided Steel Lines
Many older homes in Uptown, CA, used supply lines made from semi-flexible, non-braided metal. These lines kink easily, making them especially prone to pinhole leaks. If your home still has these lines, replace them right away.

2. Plastic Lines
Plastic tubing is an inexpensive option for supply lines, but it wears out quickly, leading to leaks and breaks. Plastic supply line manufacturers recommend replacing plastic supply lines every five years.

3. Copper Lines
Copper lines are prone to a unique type of supply line damage due to their conductivity. The main water lines in many homes are made of galvanized steel. When copper supply lines touch the galvanized pipes, the copper lines generate a weak electrical current, which is fueled by the electrolytes in clean water. This self-induced current causes corrosion to the copper lines, making them more likely to leak or break. If your home uses galvanized pipes, you should replace any copper supply lines.

4. Braided Steel Lines
Supply lines made from braided steel are the least likely to break or leak. Many come with lifetime warranties and should not need to be replaced unless they show signs of wear.
A supply line leak can lead to a big mess. Remember to inspect your bathroom supply lines regularly. If you notice any signs of supply line damage, such as water spots, a musty smell, or any worn-looking areas, it’s best to replace the lines.
