The answer to 'how long does supply line last' is that the typical lifespan of a plumbing supply line is 5-10 years, though it can vary depending on the material and usage. Supply lines are the flexible hoses that connect your faucets, toilets, washing machines, and other plumbing fixtures to the main water supply. They are prone to wear and tear over time due to pressure, temperature changes, and mineral buildup. Regular inspection and timely replacement can help prevent costly leaks and water damage.
Supply lines made of stainless steel or braided stainless steel tend to last longer, around 8-10 years, while plastic or rubber supply lines may only last 5-7 years. Factors like water quality, frequency of use, and proper installation can also impact the lifespan. It's a good idea to check your supply lines annually and replace them if you notice any cracks, leaks, or signs of deterioration.
