The answer to 'water line maintenance' is to regularly inspect, clean, and maintain your home's water lines to ensure they are functioning properly and to prevent costly leaks or water damage. This includes checking for signs of wear, corrosion, or blockages, and addressing any issues promptly.
Recommended maintenance tasks include visually inspecting exposed water lines for leaks or damage, flushing the lines to remove sediment buildup, and testing the water pressure and flow. You should also be aware of the location of your main water shutoff valve in case you need to quickly turn off the water in an emergency.
