Is there a strange noise coming from your pipes (pinging, hitting, hammering, knocking, shaking, vibrating)?

As a new homeowner, the sudden, loud banging noises coming from your plumbing system can be unsettling. However, don’t let your imagination run wild with worries about bursting pipes and catastrophic water leaks. More often than not, these unsettling noises, known as water hammer, are an annoyance rather than a disaster. That being said, they are not something to be ignored. Let’s delve into the issue of water hammer and how you can tackle it.

Understanding What Water Hammer Is

Picture this: You’re driving along a highway, enjoying the speed and the wind in your hair. Then, suddenly, you see a stop sign ahead. You slam on the brakes, and your car skids, tires screeching, before finally coming to a jarring halt. That’s pretty much what’s happening in your plumbing system when you experience water hammer.

In the world of science, water hammer is known as hydraulic shock. It’s a situation where an abrupt stop in the water flow within your pipes creates high-pressure shock waves. These waves reverberate through your plumbing, resulting in the unsettling, hammer-like sounds that can make you jump out of your skin. Essentially, your water is in a high-speed chase, and when it’s forced to a sudden stop (like when you shut off your faucet), it responds with a loud protest.

It’s as if the water, enjoying its unobstructed path, suddenly encounters a red light (a closed valve) and has to slam the brakes, causing a ruckus. And just like a hasty driver can cause a fender bender, your racing water can cause a racket in your pipes. But don’t worry, we’ll soon discuss how to ease off that ‘pedal’ and bring about some peace and quiet in your home.

Recognizing the Causes of Water Hammer

You might be wondering, “What’s turning my peaceful home into a percussion concert?” Well, the primary suspect is high water pressure. If the water in your pipes is pushing past 60 psi (pounds per square inch), it’s like a race car driver flooring it on the highway. All that speed and pressure can lead to quite a racket when the water has to come to an abrupt halt.

Meanwhile, let’s take a moment to appreciate air chambers. These little heroes of your plumbing system are short, vertical pipes situated near the water valves, serving as cushions to absorb the shock waves when water comes to a sudden stop. Picture them as the shock absorbers in a car, smoothing out those bumpy rides.

But sometimes, even these heroes can falter. Over time, they can fill up with water and lose their shock-absorbing capacity. Think of it like a sponge that’s already saturated with water—it can’t absorb any more. That’s when you start hearing those loud, hammer-like sounds.

In the end, it’s all about balance. Your plumbing system, much like a finely tuned orchestra, needs the right pressure and the proper functioning of its instruments (in this case, the air chambers) to perform harmoniously. Too much pressure, or faulty instruments, and your peaceful symphony turns into a cacophony. Now that we understand the causes, let’s move on to how we can keep this unwelcome drum solo at bay.

Here’s a step-by-step guide to get you started:

First, find your home’s main water valve and switch it off. This prevents any new water from entering your system while you’re trying to drain it. Once you’ve done that, it’s time to move on to the faucets.

Starting from the highest point in your house, open all the faucets. This includes sinks, showers, tubs – any fixture that dispenses water. While you’re at it, give the toilets a good flush too. The goal here is to drain as much water as possible from your system, allowing the air chambers to reset.

As the water drains from your pipes, the once waterlogged air chambers get a chance to dry out and regain their shock-absorbing superpowers. Picture them as tiny sponges, squeezed dry and ready to soak up the pressure all over again.

Once you’ve opened all the faucets and flushed all the toilets, from the top of your house down to the ground floor, you’re nearly done. The final step is to switch the main water valve back on. As water begins to flow back into the system, the air chambers should do their job, absorbing any sudden stops in water flow, and thus, helping to prevent the dreaded water hammer.

Remember, troubleshooting plumbing issues can be a bit like detective work. It might take a few tries to get it right, but with patience, your peace and quiet can be restored. Your future, water hammer-free self will thank you. So go ahead, roll up your sleeves and give it a shot!

Preventing Future Water Hammer Issues

Stepping up to the plate of proactive homeownership means outsmarting potential issues before they become headaches. When it comes to the vexing issue of water hammer, there are steps you can take to keep those noisy pipe concerts from making a comeback. It’s all about embracing the mantra of ‘Prevention is better than cure.

Regularly flushing out your water system, as described earlier, is like giving your plumbing a regular health check-up. This ensures that the air chambers—your plumbing system’s shock-absorbing superheroes—stay in top form. Imagine it as hitting the refresh button on your pipes, restoring those air chambers to their full, shock-absorbing glory.

But we don’t stop at system flushes. When it comes to your daily interactions with faucets, there’s room for improvement as well. We all know the satisfaction of swiftly turning off a faucet after filling a pot or rinsing a dish, but this abrupt closure can contribute to water hammer. Instead, consider closing faucets gently and slowly, like a cat sneaking past a sleeping dog. It’s a small adjustment, but it can help prevent sudden changes in water flow that can cause those pesky, loud noises.

In essence, preventing water hammer is a dance—a rhythmic interaction between your habits and your home’s plumbing. By staying mindful and making these small changes, you can help keep your pipes singing in harmony rather than hitting a jarring note. The peace and quiet in your home (and your nerves!) will appreciate the effort. It’s time to take the lead in this dance and keep water hammer at bay. It’s your home, your move.

When to Call a Professional Plumber

Adopting a DIY approach can often be rewarding and cost-effective, but it’s important to know when it’s time to pass the baton to the pros. Not every noisy pipe can be quieted with a system flush or gentle faucet closure. If you’re still jolted out of your peace and quiet by the stubborn sound of water hammer, it might be time to bring in a certified plumber.

Think of it like a stubborn toothache that persists despite all your home remedies. You wouldn’t hesitate to visit the dentist, right? Similarly, persistent water hammer might be a symptom of a deeper plumbing issue that requires a professional eye. It could be that your pipes are incorrectly sized, or there might be a need for additional air chambers.

In cases like these, a professional plumber can diagnose the exact issue and provide a comprehensive solution. They have the expertise, experience, and tools to ensure that your plumbing system gets back on track and stays that way. After all, they’re trained for this, much like a doctor is trained to diagnose and treat illnesses.

Moreover, it’s not just about solving the current problem. A professional plumber can also give you expert advice on how to maintain your plumbing system to prevent future issues. They can help you understand the ins and outs of your specific plumbing system and provide practical, easy-to-follow advice tailored to your home’s needs.

So, while it’s admirable to roll up your sleeves and try to fix things on your own, there’s no shame in calling in reinforcements when necessary. Sometimes, it’s the most effective, efficient, and ultimately, the most cost-saving way to ensure your home remains a peaceful haven free of water hammer.

FAQs About Water Hammer

What are the steps to rectify water hammer?

To resolve this issue, it is necessary to evacuate the plumbing system by shutting off the primary water valve and activating the highest faucet in your residence. Subsequently, remove the water from the faucet located at the lowest point. Once the water is emptied, the chamber should become filled with air, effectively resolving your water hammer issue.

What is the cause of my abrupt occurrence of water hammer?

Water hammer often occurs due to the presence of trapped air within the system. If empty piping is filled too rapidly, air might infiltrate the pipework system. In order to reduce the likelihood of air getting trapped in the system, it is important to fill the piping gradually to allow for the release of any air.

Is it possible for water hammer to cause pipes to burst?

Affirmative. A water hammer can lead to a pipe rupture, which occurs when there is a fracture in the pipe system. This phenomenon arises when the pipe lacks the capacity to withstand the pressure, resulting in its rupture or bursting. This can also occur when the pipe joints deteriorate due to the hydraulic shock’s pressure.
