The answer to 'supply line maintenance' is to regularly inspect and clean your plumbing supply lines to ensure they are functioning properly and to prevent leaks or water damage. Supply lines are the flexible hoses that connect your plumbing fixtures, such as sinks, toilets, and washing machines, to the main water supply.
To maintain your supply lines, start by visually inspecting them for any signs of wear, such as cracks, bulges, or leaks. If you notice any issues, it's best to replace the supply line as soon as possible to avoid potential water damage. Additionally, you should clean the supply lines periodically by flushing them with water to remove any buildup of sediment or mineral deposits.
