What’s Causing Loud Banging in My Pipes?
You turn off the water, and bang! The whole house jumps. Maybe it’s the washing machine. Maybe it’s the kitchen sink. Either way, that sound makes your stomach drop a little. It’s loud, sharp, and every time it happens, you wonder if a pipe’s about to burst.
Don’t panic. That noise has a name—water hammer—and it’s something almost every Tacoma homeowner hears at some point. What’s happening is simple: water is moving fast through your pipes, then suddenly gets stopped. The momentum doesn’t just disappear—it slams into the shut valve. That shockwave makes your pipes shake or knock against whatever’s nearby.
At 2 Sons Plumbing and Sewer Tacoma, we get calls about this all the time.
Why It Happens
Your plumbing is always under pressure. When water stops too quickly—say when your washer finishes filling—the flow hits a dead end and has nowhere to go. If your pipes aren’t secured tightly, they’ll rattle. If the system doesn’t have room to absorb pressure, it’ll “hammer.”
Common causes we see around Tacoma homes:
- Loose pipes that aren’t strapped tight to the framing
- Quick-closing valves on dishwashers or washing machines
- Old air chambers or arrestors that have filled with water and stopped doing their job
Sometimes, it’s just one loud thud. Other times, it’s a series of clanks that seem to echo through every wall. Either way, it’s your plumbing saying, “Hey, something’s off.”
A Few Quick Fixes You Can Try
If the banging isn’t constant, try these before you call anyone out:
- Secure what you can see. Check under sinks or in the basement. Strap loose pipes with padded clamps.
- Drain and refill the system. Turn off the main water, open all the faucets to empty the lines, then close them and turn the water back on slowly. This helps reset the air cushions inside the plumbing.
- Go easy on the valves. When you turn off a faucet, do it gently. It sounds silly, but it can help.
If the noise keeps coming back—or you’re hearing it in several spots—it’s time to call a plumber. That usually means your home needs something called a water hammer arrestor.
What We Do to Fix It
When we show up to a Tacoma home with noisy pipes, we don’t just guess. We listen, check pressure, and figure out exactly where that hammer is coming from. If it’s loose pipes, we strap them. If pressure’s too high, we correct it. If the system needs arrestors, we install them near the problem valves.
Those little devices act like shock absorbers—they take the hit so your pipes don’t. Once they’re in place, the noise stops. Instantly.
What It Costs
Most homes need one or two arrestors, and they usually cost between $250 and $600 each, depending on where they’re installed. If it’s just loose pipes or minor adjustments, it can be less. Either way, it’s cheaper than dealing with a leak or broken fitting later.
Call 2 Sons Plumbing and Sewer Tacoma
If your pipes are banging, don’t just live with it. It won’t go away on its own—and you shouldn’t have to cringe every time someone turns off the water. Call 2 Sons Plumbing and Sewer Tacoma at (206) 487-1757. We’ll find what’s making the noise, fix it fast, and leave your home quiet again.

UPDATE: Adam returned to do the repair work for a leak in my crawlspace. He was timely with his arrival, inspected the area, and very clear about cost and the work he would be performing. He worked efficiently and tested thoroughly when he was done. Very happy with the service that I got both days with 2Sons Plumbing and will definitely call them again if needed and recommend them to others.
Riley did an excellent job helping me to diagnose an issue with a pipe in my crawlspace. It was a difficult space to navigate through, but he was able to get photos and videos then talk through a game plan and confirm a path forward. I very much appreciated his help and guidance. I would definitely call him back if I need more work done

I had a phenomenal experience with Carey, Carson, Cody, and Salvador! I had them install a new dedicated line to a water hydrant in my yard and it the project turned out perfectly! I want to especially commend Casey for going out of the way to figure out the best way to achieve what I wanted (he actually suggested the hydrant after considering what I wanted in my project). He worked professionally to give me the best possible quote he could for the project and saved me some serious $$! They trenched a 60ft 22 inch deep trench, ran the pipe, and put all the pavers back on my patio and the job site was perfectly clean when they were done.
All of them worked insanely hard over 2 days to do the trench since there were a ton of rocks in my yard which wasn’t known just how difficult it would be at the time. Instead of charging me more they just finished the project to completion.
I would recommend them to anyone looking for an excellent experience for plumbing work! I’ve already told several people what a great and difficult job they did!

We cannot recommend 2 Sons Plumbing and Sewer enough - they were the only company out of 5 I had contacted that could come out the same day. Our plumber, Jacob, was polite, thoughtful, and very knowledgeable. He quickly diagnosed the issue and shared several options to fit within our budget and did his best to keep our costs down. Great guy and great service!

Carey did an amazing job diagnosing and fixing a water leak which started in my bathroom and seeped into the garage below. He came within an hour or two after I called the company, right after his previous job. He was fast, friendly and informative. He even helped me find my water main in case I need it for future. Definitely calling this company if I need help with a water/plumbing emergency in future.

This was my second time using 2 Sons plumbing. I received a call about scheduling the appointment for the next day. Jake was very professional. He explained my choices for the service and didn't push the most expensive option. Even though the scope of the job changed during the visit it was completed that same day. He did a good job and cleaned up the worksite. Would definitely recommend.

I had a great experience with 2 Sons Plumbing and Sewer. I scheduled an appointment online last night, and they called me first thing this morning. Natalie was so kind and even offered me an earlier appointment that same day, which I really appreciated.
Justin came out and was friendly, professional, and honest. He gave me a fair estimate for the repair I needed and also provided estimates for a few additional code-related fixes that may need to be addressed in the future. I never felt pressured to approve any extra work, which I really appreciated.
From scheduling to the service visit, the entire experience was easy and professional. I would definitely use 2 Sons Plumbing and Sewer again and would happily recommend them to others!

I had a project that required a quick turnaround for some temporary top-out plumbing, and Two Sons Plumbing was incredibly responsive from the start. They came out quickly to provide a quote and, even during what I know is their peak season, they prioritized getting my project scheduled. That level of customer service was greatly appreciated.
The quote was a bit of sticker shock, but that’s simply the reality of the Seattle market—not a reflection of their service. What really stood out was that the same person who came out to provide the estimate also completed the work. It meant I didn’t have to explain everything twice, and we’d already built a level of trust before the job even started.
The quality of the work was excellent, and they even went above and beyond by replacing a damaged toilet lid at no extra charge. Small gestures like that make a big difference.

Had a great experience with 2 Sons Plumbing and Sewer and the representative they sent, Jake. They did a fantastic job communicating through email, text, and calls, sending reminders when the appointment was and who their representative was, and when he would arrive. Jake did a wonderful job hunting done where the leak was coming from and explaining the options I had for getting the leak repaired. When he left he emailed my receipt, pictures he had taken of my water lines under the house, and the options I could use to compete locating and repairing the leak. Highly recommend them. A very professional outfit.

I asked some of my real estate colleagues who people have been using for plumbing repairs lately and several said “2 Sons”! So friendly and responsive. Came out right away for an estimate, had the best follow up, came in with the best price, and got me on the schedule and got the work done on the very next day! Everyone I spoke with was friendly and fantastic! Highly recommend!

We had a mystery leak per our meter reading. Riley and Riley saved the day. They promptly discovered the issue, resolved and repaired our pipes in one service call. They were quick, thorough and entirely delightful. They took the time to talk me through the job. I felt heard, safe and comfortable with the two of them in my house. For my next plumbing disaster I hope to get ‘The Riley’s’; but know, whoever comes will be excellent. Thanks 2 Sons!
