The importance of inspecting plumbing supply lines

Those little metal flexible hoses that connect to your laundry machine or your toilet? Those are plumbing supply lines, and they often go unnoticed until a leak occurs and disaster strikes. Regularly inspecting and replacing these lines is crucial to prevent potential flooding and water damage. It's a habit you should get in to right now.
 


Why is it so important to check plumbing supply lines?

Leaking or burst plumbing supply lines are a leading cause of water damage. In fact, according to the National Association of Home Builders (NAHB), failed lines are the root cause for over 50% of all residential insurance claims. That's because a burst line can cause severe flooding within minutes. 

To help avoid a major water damage incident, plumbing supply lines should be visually inspected at least twice a year, or more frequently in high-use areas.
 

How to tell if you need to replace a plumbing supply line 

  • Wear and tear, including cracks, bulges, or brittleness caused by exposure to hot water and constant pressure. These signs indicate the hose is deteriorating and more prone to leaks.
  • Corrosion, which weakens the hose's integrity. Look for signs of rust, discoloration, or flaking on the surface of the hose and connectors.
  • Loose or damaged connectors, which can lead to leaks, even if the hose itself is in good condition.
  • Fraying or splitting, especially near the connections. These signs indicate the hose is nearing the end of its lifespan and should be replaced immediately.

What do I do next?

  • Promptly replace damaged hoses. They are inexpensive and can be bought at most hardware stores.
  • Replace hoses proactively, even if they appear to be in good condition. The average lifespan of a water supply line hose is 3-5 years.
  • Avoid kinks or twists to prevent unnecessary strain and reduce the risk of leaks or bursts.
  • Call a plumbing professional if a hose is difficult to access, or if you're unsure of your ability to make the replacement yourself. 

Regularly checking and replacing water supply line hoses is essential for preventing water damage, flooding, and the growth of mold and mildew. Stay vigilant in maintaining these hoses to protect your property, belongings and the well-being of your home.
