What Causes Loud Banging or Hammering in My Pipes?

You’re winding down after a long day in Auburn, you turn off the faucet — and suddenly a loud bang echoes through the walls. It can be startling, even a little worrying. Many homeowners describe it as pipes “knocking” or “slamming.”

This is what plumbers call “water hammer.” It happens when water flow stops too suddenly, sending shockwaves through your plumbing. Those shockwaves shake the pipes, and that’s what creates the banging sound.

At 2 Sons Plumbing Auburn, we see this often in both older homes near downtown and newer builds in Lakeland Hills or Lea Hill. While it may seem like just noise, over time it can loosen joints, stress fittings, and even cause leaks. The good news? It can be fixed.

Easy DIY Fixes to Try First

Before calling in a pro, Auburn homeowners can try a few simple steps:

Secure loose pipes – Use brackets to hold rattling pipes in place.
Drain and refill the plumbing system – Restores air cushions that absorb shock.
Close valves gently – Slamming faucets or appliance valves makes hammering worse.

These tricks often help, especially in little-used bathrooms or kitchens. But if the noise happens often — or across multiple fixtures — it’s usually a bigger issue.

Call 2 Sons Plumbing Auburn at (206) 487-1757. We’ll inspect your system, explain the cause, and restore the peace and quiet you deserve.

When to Call a Licensed Auburn Plumber

If water hammer keeps coming back, the solution may be installing water hammer arrestors. These devices act like shock absorbers and stop the banging before it starts. You should call us if:

The noise happens in more than one room.
Washing machines or dishwashers trigger it.
Pipes rattle even after you strap them down.
DIY fixes haven’t worked.

In Auburn, water hammer arrestors typically cost $250–$600 each depending on your system. While that’s an investment, it’s far less than repairing water damage from burst pipes later.

At 2 Sons Plumbing Auburn, our licensed plumbers handle this problem every week. We use professional tools, follow city plumbing codes, and make sure the solution lasts.

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!
