A leaky faucet used to mean a ten-cent washer and a quick fix. These days, most modern faucets are not built that way — manufacturers design them as sealed units, so when they start leaking there is no washer to change. Here is the honest version of this job.
Can you still fix a faucet by changing a washer?
On older two-handle faucets, yes — a worn washer or O-ring is often the culprit and it is a cheap fix. But most faucets sold in the last fifteen years or so use cartridges, and many are sealed. When they leak, the washer aisle at the hardware store cannot help you. Check the product description or manual before buying parts — if it does not list replaceable washers or a cartridge, do not waste the trip.
What is the real fix for a modern leaky faucet?
Replacing the whole faucet. A decent kitchen or bathroom faucet runs $50 to $150, and swapping it yourself is a 30 to 60 minute job with basic tools. It is the faster, surer fix — and you get a new faucet out of it.
How do you replace a faucet? Step by step.
- First, turn off the water using the two valves under the sink. If there are none, turn off the main water shutoff.
- Second, put a towel down and disconnect the supply lines with a wrench — some water will spill.
- Third, unscrew the mounting nuts holding the old faucet from underneath the sink.
- Fourth, lift out the old faucet and clean the sink surface.
- Fifth, drop in the new faucet, tighten the mounting nuts, and reconnect the supply lines.
- Sixth, turn the water back on slowly and check every connection for leaks.
When should you call a plumber instead?
If the shutoff valves are frozen stuck, the supply lines are corroded, or there is no shutoff valve at all, call a pro. Having a plumber replace a faucet typically runs $150 to $300 in most areas — still cheaper than water damage from a leak you cannot stop.
Check the description before you buy parts. If it is a sealed modern faucet, skip the washer aisle and replace the whole thing.
