Faucet Repair or Replacement: A Homeowner Decision Guide

Start with the symptom and the faucet’s age. A single drip from the spout, a loose handle, or a weak spray often points to a serviceable cartridge, aerator, O-ring, or washer. Turn off the stop valves below the sink before removing parts, plug the drain so small pieces cannot fall in, and take photos as you work so the handle and trim go back in the same order.

Repair is usually the sensible choice when the faucet body is sound, replacement parts are still available, and the leak is isolated to a wear item. Bring the old cartridge, aerator, or a clear photo of the brand and model to a plumbing supplier. Use the manufacturer’s replacement parts when possible; a nearly matching part can create a worse leak or damage the valve body.

Replacement is often the better investment when the finish is badly corroded, the body is cracked, parts are discontinued, or repairs keep returning. Also consider replacement if the faucet has chronic low flow after the aerator is cleaned, the handle is difficult to operate, or the connection below the sink shows damage. Confirm the number of sink holes, the spread between holes, mounting style, and available clearance before purchasing a new faucet.

Call a plumber if you cannot fully shut off the water, the shutoff valves leak or seize, the supply lines are corroded, or water is appearing inside the cabinet or wall. A faucet swap should not require forcing old fittings. Protecting the supply piping and avoiding a hidden leak is worth more than saving a few minutes on the repair.
