Replacing Supply Lines to Toilets and Washing Machines


How Often Should You Replace Those Braided Supply Lines?

The general rule of thumb is to replace all of your supply line hoses every 5 years as a preventative measure to protect your home against any potential leaks. But since braided supply lines have a rubber core with external reinforcement it is recommended that they be replaced every 10 years.

Appliances like dishwashers and fridge ice makers can have subtle leaks simply because they are hidden from view and slight leaks can occur for quite a long time before they get big enough for you to notice that there's a problem. They leak slowly behind the appliance, slowly dribbling water into your walls where it causes mold and rots framing members over time. 

So, being proactive and replacing your braided supply line hoses to your toilets and appliances every 10 years can help to prevent expensive major damage to your floors, etc.

If you have plain rubber supply lines to your washing machine, those should be replaced every 5 years. 

You don’t even want to contemplate the disaster that occurs when one of those lines splits open (they are always under pressure). And Murphy’s Law dictates it will only happen when no one is at home. And your insurance provider will be wanting to know when they were last replaced should anything horrible happen.
