Why Does My Faucet Drip Even When Turned Off?

That constant drip, drip, drip from your faucet can drive you nuts. It always seems louder at night when the house is quiet. And while it may not seem like a big deal, every drop adds up—wasting water and bumping up your utility bill.

If your faucet in your Bellevue home keeps leaking even when you’ve shut it off tight, chances are something small inside has worn out. At 2 Sons Plumbing Bellevue, we see this every day. The good news? Most of the time, it’s a simple fix.

Why Faucets Start Dripping

Faucets are built to shut water off completely. But over years of use, the little parts that seal the water inside wear down. Here’s what usually causes the problem:

The Washer’s Worn Out

Older, compression-style faucets use rubber washers to stop the water flow. Eventually, that washer flattens, cracks, or gets too stiff. Once that happens, water sneaks through and the dripping starts.

The O-Ring’s Shot

Many faucets have a small rubber O-ring around the stem or handle. When it dries out, cracks, or loosens up, water can leak from the spout or even around the handle.

The Cartridge’s Failing

Modern faucets often use a cartridge to control water flow. If it’s worn or damaged, the faucet might drip no matter how tightly you shut it off.

Quick DIY Fixes You Can Try

If you don’t mind getting your hands dirty, you might be able to stop the drip yourself:

Shut off the water: Look under the sink and close the supply valves so you don’t flood the cabinet.
Take the faucet apart: Remove the handle to get to the washer, O-ring, or cartridge.
Swap out the part: Bring the old piece to the hardware store and buy the exact match. Pop it back in and reassemble the faucet.

Most Bellevue homeowners can do this for $10–$40 in parts. If you’re handy, it’s worth a shot.

When It’s Time to Call a Plumber

Not every drip has an easy DIY fix. If you notice water leaking under the sink, heavy corrosion around the fixture, or if you’ve already tried replacing parts and it still drips, it’s time to call in a pro.

At 2 Sons Plumbing Bellevue, we’ll check the faucet, find the real cause, and repair or replace it. Professional repairs usually run $150–$300, depending on the faucet type and what needs to be done.

Why You Shouldn’t Ignore a Drip

A leaky faucet might seem like a minor annoyance, but it can waste hundreds of gallons of water every year. That’s money literally going down the drain. Fixing it sooner not only saves water, it prevents wear and tear on the faucet and surrounding plumbing.

The plumbers at 2 Sons Plumbing Bellevue fix leaky faucets every single day. Call us today at (206) 487-1757 for faucet repair in Bellevue. We’ll stop the leak, save you money, and give you back some peace and quiet.

I have to say Bob was amazing!!! I had a clogged drain in my kitchen sink. Bob came in and took every precaution to be neat & clean. He explained to me what he was going to do and gave me the pricing and I agreed and he got to work. He was super kind and polite and fixed my drain issue. He was a pleasure to work with. I would highly recommend using 2 Sons!

Had issues at home with water backup. Dave was prompt, professional, and genuinely kind. He communicated between myself and my landlord, explaining the issues and next steps. He quickly put an interim solution in place and outlined the long-term needs. Felt super reliable and easy to work with — highly recommend 2 Sons Plumbing.

We contacted these Plumbers on a Friday using Yelp quotes, and they were the fastest to reply and the fastest to engage with us when we had questions. We felt that warranted to give them the opportunity to give us the first consultation. Sometimes we get multiple consults if we get any icky feeling from the people doing it. We didn’t feel that way with this company.

Our toilet was leaking, and we expected we probably could use a new one. But wanted a professional estimate and options.

We got hooked up with their team to schedule it and they were able to give us a time only a day out. We asked for a 8-1pm window and received automated text and a formal phone call from a dispatcher saying how far out the plumber technician was.

The plumber who showed up was named Carey. We also a received a picture of him before he arrived for safety concerns which I thought was a good touch of care from the company. Carey was lights-out the best guy we could have asked for.

He showed up within the approximate eta and was kind, gracious, considerate of our space and gave us a myriad of options. He quoted us prices that felt quite fair, and we chose the option where he removes the toilet and chooses a toilet for us: though we talked about the various options beforehand.
All and all he left for 30 min to get the toilet: and returned to install it. Installation was complete within another 30 minutes.

He was so good man. And we just felt like this is how service and care and things should be in this world. It’s always refreshing when you get that. Because so many outfits just: make you regret everything.

The work was quick, professional, and he was happy to be there and gave us information every step of the way that we respected and appreciated.

We will use this company in the future. You earned our respect and business.

I initially hired this company to address a leak in my water service line. Due to repeated misdiagnosis and unsuccessful repair attempts, the work ultimately escalated into a full water service line replacement, resulting in a final cost far higher than what I had initially expected. While the replacement is now completed and functioning, the overall experience was frustrating and poorly managed.

From the start, pricing and expectations were unclear. I was told repair costs couldn’t be determined until excavation, yet on the day of work—before anything began—I was asked to sign for a high fixed repair price based on assumptions that were never discussed during the estimate.

The first repair attempt failed, and the leak clearly continued. No further investigation was done, I was required to pay in full, and I was told a discount would only apply if I committed to a full water service line replacement the same day, before the issue was properly resolved.

After paying for a second leak detection myself, the original leak was confirmed to still be present. Management involvement was requested but delayed, and during a follow-up visit I was asked to sign a new agreement stating the work was only a “repair attempt” with no warranty, despite the original repair being sold as warrantied.

I later proceeded with the water service line replacement based on specific assurances about the final cost, but the estimate I received did not align with those assurances. Throughout the process, I had to make multiple phone calls and send repeated emails over several days just to get responses.

While the final replacement works, the lack of technical competence, shifting pricing and warranty terms, and consistently poor communication made this an unnecessarily stressful experience. I would not use this company again.

Carey and Micah came out on short notice when our tankless water heater started leaking unexpectedly. They were able to provide an extremely competitive quote on site and schedule us for installation the next day. We had some other pre-scheduled contractors in our home when they did the installation and they were extremely professional and courteous in making space for them to share space. I also appreciate how they cleaned up after work was completed. Overall wonderful guys and our second time using 2 Sons (once prior was to have a sewer line cleared) and we'd absolutely use them again. Thanks, Micah & Carey for the work!

I want to start by saying that Jeff and the rest of the plumbing team are absolutely great. They are very knowledgeable, professional, and clearly know what they’re doing. The quality of their work is solid, and I never felt like I was dealing with people who didn’t understand their craft.

That said, the pricing is extremely high. I completely understand paying for quality and expertise, but the cost made it hard to move forward with them for future work. If their prices were more reasonable, they would 100% be the company I would use every time.

So if budget is not a concern, you’ll likely be very happy with them. But for those of us who have to balance quality with affordability, the pricing is something to seriously consider.

I had a kitchen sink that started draining very slowly. Scheduling with 2 Sons was quick and easy. The technician arrived on time and was polite and friendly. Unfortunately, he was unfamiliar with the pipe configuration in my condo building and told me he was unable to get the cable through. He then provided me a written estimate for over $1600 to reconfigure the pipes. He stated the drain could not be cleared until that work was done. I was charged over $500 even though he was unable to do any work (got the cable down the pipe less than 5 feet before he gave up.) I called another plumber who came out a few days later and was able to use the cable to clear the drain (exactly what the plumber from 2 Sons said could not be done). I have emailed 2 Sons three times, explaining my concern and requesting a refund of the fee I paid, but am having difficulty getting anyone to respond to me. Overall, a very frustrating experience. I cannot recommend them based on this experience and lack of response.

We have used 2 Sons Plumbing quite a few times now and have never been disappointed! Courteous, professional, knowledgeable and efficient describes everyone from the office to the field teams! One of their team members, while here installing a sink fixture, overheard an estimate we were getting from a visiting sales rep for a project. Their team member (Carey) offered that the estimate was way over priced (by over $20k). We had 2 Sons price it out for us and they came in $23k less. We have a couple planned projects upcoming and plan to use them for that as well as any unexpected issues that arise. Just this week, they dispatched a team on NYE as our water heater broke. Once again, good price, courteous, professional and efficient! I/we are so pleased to have found this company! We highly recommend them!
