The answer to 'how much to fix supply line' depends on several factors, but typical costs can range from $100 to $500 or more. The exact price will depend on the location and extent of the repair, the materials needed, and whether any additional plumbing work is required.
Common factors that influence the cost of a supply line repair include the type of pipe (e.g., copper, PVC, or PEX), the length of the supply line, the accessibility of the line, and whether any other related issues need to be addressed, such as a leaky faucet or a damaged shutoff valve. Labor costs can also vary based on your local plumber's rates.
