Why Is My Faucet Dripping Even When Turned Off?

That continuous drip, drip, drip is extremely irritating! But, it is more than that – it’s literally money going down the drain. Over time, a dripping faucet can waste gallons of water but most homeowners don’t realize how fast it adds up on the monthly bill. If your faucet keeps leaking even when you’ve turned it off tightly, something inside it isn’t doing its job anymore. At 2 Sons Plumbing Federal Way, we run into this problem all the time, and the fix is usually straightforward once you know what’s going on.

The Most Common Reasons Faucets Leak

Faucets might look simple on the outside, but inside they’ve got small moving parts that take a beating every day. When one wears out, the dripping starts. The usual suspects are:

Washers that have worn down. These rubber pieces press against the valve seat. Once they flatten out or crack, water sneaks through.
Cartridges that go bad. Once the cartridge inside in a cartridge faucet fails, no amount of tightening the handle will stop the drip.
Old O-rings. These little rings make a tight seal where parts join together. Once they wear out, leaks follow.

These parts don’t last forever. After years of twisting the handles on and off, they just give out.

What You Can Try Yourself

If you don’t mind rolling up the sleeves, a dripping faucet is something you might fix yourself. Here’s how to go about it:

Turn off the shut-off valves under the sink.
Remove the handle—usually a simple screw or hex key.
Check the washer, cartridge, or O-ring. If one looks worn or cracked, that’s your problem.
Swap in a new part. Take the old piece to the hardware store to ensure an exact match.

Most replacement parts are affordable and quick DIY repair is feasible if the faucet is in otherwise good shape.

When to Bring Over a Plumber

Of course, every leak is not that simple. If the drip is coming from underneath the sink, if the faucet body is corroded, or if you’ve already tried replacing parts and it’s still leaking, it’s time to bring in a pro. A licensed plumber can tell whether it’s worth repairing or if replacing the faucet is smarter in the long run.

What It Costs in Federal Way

Here’s what you’re looking at for costs:

DIY parts: usually $10–$40
Professional repair: $150–$300, depending on the faucet type

It’s a small price to pay compared to letting water drip 24/7, which can waste hundreds of gallons in a month.

Our house decided to replace our own toilet, but we got stuck halfway through because we didn’t have the right tools and accidentally broke an anchor bolt. I called 2 Sons Plumbing, and they showed up within an hour to help us out. Derek, our plumber, was super friendly, explained everything clearly, and got the job done quickly and professionally. Excellent service all around—highly recommend!

Dave and David came and cleared out a huge clog in my kitchen sink (both sides) that has been plaguing us for a while as well a ton of glass shards that got into the drain when our glass fridge shelf broke. Dave walked us through each step of the process and explained everything which was excellent. He also gave us advice about galvanized piping replacement. They even gave us a few free parts for the sink drain that had eroded away and didn’t charge extra for it!! All around 5 star service!!!

Fantastic service and communication. Local company. Solved my clogged basement laundry utility sink. Dave and David were courteous, informative, professional and easy to engage with. Scheduling was easy (they came the next day) and they arrived within the expected time window. Transparent pricing and i could also apply a coupon. I will use them again.

Great service and Dave their plumber is the best. We have an odd house with even odder plumbing. The pipes are a mess of grandfathered-in open air nonsense, when our pump started making some noises (and a little leaking) after some DIY heat tape adventures (getting ready for colder weather), we were worried that we would need a massive repair but Dave came and looked at it and immediately realized we had unplugged the float plug from the pump plug which was 90% of the problem and the leak just need a little tightening of a flex joint. The company was quick and didn't charge for an estimate or in this case a quick "thats not plugged in right". The experience and the overall professionalism has convinced me that when I do finally need that big repair job, I'll call these guys.

Booking an appointment was extremely easy, and we were able to get one just the next day. Communication was excellent with timely reminders and a call before our appointment. Kerry did a fantastic job both advising us and effectively resolving our issue.

I have all good things to say about 2 Sons Plumbing. My first experience was a few years ago and the whole process went very smoothly. Making the appointment was easy and quick, the repair was done with no problem and I thought the price was fair. Recently, Dave from 2 Sons came out to look at several plumbing problems I was having and, within a matter of minutes, all of the problems were diagnosed. Dave gave me options and estimates all before he left my house. I haven’t had the work done yet but appreciate the information and the prices seemed fair to me. Dave was on time, professional and very knowledgeable. 2 Sons are my go to Plumbers.

Bob at 2 Sons Plumbing was amazing! We had a horribly backed up kitchen sink drain and he was able to fix it, and save us some money in the process! He heard what we had to say about our issue and double checked everything. Super friendly and very helpful. Thank you for the amazing work Bob!

Stellar job by Carey and his team at 2sons today. I had a complex job -- installing a yard hydrant/faucet for a garden across the (private) street. They had to go into the floor of the garage, run piping under the floor, out of the house, across the road. Had to cut into the asphalt, trench down a couple feet, then patch it all up again, including fixing the garage concrete floor. Super job. Looks really clean. Got it all done in a day.

A wonderful experience every time with 2 Sons plumbing. Jake and Angelo helped us with our plumbing issue. They showed up on time and gave a very reasonable estimate for the repair. We ended up replacing a couple of toilets and a part of a sink drain. They came back the next day to complete the work due to our schedule. Excellent communication, prompt, and hard working! Thank you so much Jake and Angelo!! We are very happy with 2 Sons and have used them multiple times.
