How Do I Stop Water Hammer Sounds in My Pipes?

Hearing loud banging or thudding sounds from your plumbing? You’re likely dealing with water hammer. This isn’t just annoying—it can indicate issues that may wear down your pipes and fixtures over time. At 2 Sons Plumbing Seattle, we’ve helped countless homeowners track down and stop these disruptive noises before they turn into serious problems.

Water hammer occurs when flowing water is forced to stop suddenly. The resulting shockwaves rattle your pipes. Sometimes the sound comes and goes, but persistent banging signals that your plumbing system needs more than a quick DIY fix.

Quick Fixes Seattle Homeowners Can Try

For mild water hammer, try these simple steps:

Secure loose pipes – Fasten any visible pipes to reduce rattling when water pressure shifts.
Close faucets gently – Slamming valves shut makes the shock worse; ease them closed slowly.
Drain and refill your system – This can help built-in air chambers absorb pressure surges properly.

These steps can help if the issue is minor. But if the hammering continues, it often points to a deeper problem. Consistent noise across several fixtures or appliances usually means you need a professional solution.

Don’t wait for the banging to worsen. If DIY fixes haven’t solved it, call 2 Sons Plumbing Seattle at (206) 487-1757 for expert help.

When to Call a Seattle Plumbing Professional

Water hammer that doesn’t improve is often caused by more than loose pipes. In many homes, the best long-term fix is installing water hammer arrestors—devices designed to absorb pressure spikes before they shake your plumbing.

Call a licensed plumber if:

The banging happens in multiple areas of the house
The noise gets louder or more frequent
You see leaks, worn joints, or signs of plumbing stress

Our trained technicians know how to inspect your system and install arrestors in the right spots. Professional installation not only stops the noise but protects your pipes from long-term wear and costly damage.

What It Usually Costs

Typical water hammer arrestor installation in Seattle runs between $250 and $600 per device, depending on the layout of your home. When installed properly, these devices offer long-lasting protection and noticeably quieter plumbing.

Seattle’s Trusted Answer for Lasting Plumbing Solutions

Ignoring water hammer or guessing at repairs can lead to more than sleepless nights—it can cause leaks or major pipe damage. That’s why so many Seattle homeowners rely on 2 Sons Plumbing for dependable, long-term plumbing solutions.

Thank you, Bob, for your professional, courteous, and kind service! My downstairs tub was running with high pressure due to some worn out stems. Bob was thorough—but unfortunately our fixtures are quite old, and he didn’t have appropriate replacements available the first day. However, they were able to find the appropriate stems for our tub and fixed the leak right away day 2. I cannot speak highly enough about how grateful I am for the way 2 Sons accommodated my schedule when they needed to return with the appropriate fixtures. The technician was a genuine joy to work with—and I appreciate the quick follow up and turn around. I also appreciate the way Bob walked me through the process and double checked for leaks.

We had a great experience. Brandon and Chris were very polite and professional. We had a massive leak under a toilet and they came and fixed it on a Saturday. They were very timely and hardworking. Ethan was another who was also very polite and professional. Pricing was also very manageable for the extent of the problem we had. I would highly recommend.

I had a great experience with 2Sons Plumbing. Communication was on point from start to finish. Dave arrived on time, was very friendly, and knowledgeable. He also gave me a helpful heads-up about our heater and offered great advice. I really appreciate the professionalism and will definitely use them again!

We really enjoyed our experience with 2 Sons. We had an emergency that had water all over our kitchen and basement. They were able to send someone out later in the evening for us after several other companies either cancelled on us or said they couldn't come until the next day. Our technician/plumber Riley was great to work with - friendly, quick, and effective! They even gave us a call back a few days later to check in on our experience and to answer some extra questions we had. Highly recommend!

I have not decided to go with 2 Sons for the plumbing issues I have yet. However, I am very impressed by the technician, Guy, who came for the appointment. He was professional, friendly, knowledgeable, courteous, and thorough. I told him that I was just getting a quote and not ready to commit to do the repair right away. He was very understanding. I have a clogged kitchen sink, disconnected washer hose causing water damage, and likely a disconnected pipe behind the wall. He explained the steps I need to take before he can help for all three issues. Like I should hire the restoration company to repair the water damage before reconnecting the pipes. He also helped to take pictures and referred me to a restoration company for the jobs outside of his scope. Before he left, he measured the water pressure to make sure the pressure is within a normal range. Just to make sure the water is not putting too much pressure on the fixtures resulting leaks. It was definitely a surprisingly pleasant and thorough experience with Guy.

Excellent service from 2 Sons Plumbing – highly recommended!

We recently had 2 Sons Plumbing come out to fix several issues at our place. We couldn’t be happier with the results. Marcos and Chris were absolutely fantastic — professional, knowledgeable, and very thorough in their work. Every single job was done with precision and care.

Marcos and Chris took the time to explain what they were doing, answered all our questions patiently, and made sure everything was up to code and functioning perfectly before they left. They worked efficiently, left the area spotless.

It’s rare to find such reliable, honest, and detail-oriented professionals these days. I wouldn’t hesitate to recommend them to my friends and neighbors.

I called 2 Sons Plumbing and was able to get them to come out to the house the very next day. The over the phone customer service were very personable and friendly. On the day of my appointment, Bob was the one sent to our house to fix our kitchen faucet. Bob was extremely friendly and helpful in fixing my faucet. He was very considerate and quick with his work. I did not feel like I was being taken advantage of or overpriced as far as how much they were charging. Bob was always transparent with the cost and also trying to find the most cost-effective way to accomplish what needed to get done? I would recommend 2 Sons plumbing to anyone who needs plumbing service. 2 Sons plumbing has a gem for an employee (Bob). If I were to call 2 Sons plumbing again for service, I would definitely want to request Bob as my priority person.
Thankyou so much

After the recent power outage I discovered that my combi-boiler went on the fritz, meaning no hot water and no heat in my home—a very chilly situation for Seattle fall. 2 Son’s was so friendly and able to send out Adam same-day which was a huge relief! Adam quickly assed the issue, fixed it and provided a thorough explanation of what he did to get the system up and running again (which I deeply appreciated). I am thoroughly impressed by his knowledge of these units; turns out the pressure reducing valve on my machine also needs to be replaced, which explains why my water pressure has always been a bit funky between hot and cold. Adam provided an affordable proposal for a future repair to my unit for optimal functioning. Would absolutely recommend Adam and 2 Sons!

Had a great experience with 2 Sons Plumbing, Heating & Air. Their scheduling system was smooth — I got a call when Carey was assigned, could track his arrival, and everything ran on time. Carey was fantastic! He inspected the garbage disposal, coordinated with my property manager for approval, and quickly installed the new system. He was respectful, efficient, and made sure everything worked perfectly. Really appreciated his help!

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!
