Plumbing pipes make noise

Have you ever wondered why your pipes tend to make noises? Those strange sounds you hear in the night from your plumbing have various causes, ranging from normal functioning to pressing issues. In this detailed article, we will explore why your plumbing pipes make noise and how you can address these issues.

Heat-Induced Expansion and Contraction

Pipes are made of materials that expand and contract as temperature changes. When hot water flows through them, they expand, and when the temperature falls, they contract, leading to different types of noises. Pipes rubbing against each other or loose brackets may result in clunking or creaking noises.

The Science of Water Hammer

Water hammer is a common noise issue in numerous homes’ plumbing systems. This noise comes about because when water rapidly stops or changes direction, it sends shock waves that reverberate through the pipes causing a loud hammering sound. Water hammer can be quite damaging over time if left unresolved.

High Water Pressure

If water pressure in your pipes is excessively high, it can lead to various noises including banging and knocking sounds. Extremely high pressure strains valves and creates turbulent flow which leads to noise production. Furthermore, it accelerates wear-and-tear on your system.

Loose Pipe Issues

Pipes that are not tightly anchored can cause clattering or banging noises as water flows through them due to their movement. Ensuring correct installation is key for minimizing this kind of noise and maintaining an effective plumbing system.

Aging Pipe Systems

Just like any other system, plumbing pipes age over time. Older pipes may produce hissing, clunking, or whistling noises. This could be a signal for you to consider replacing your old pipes.

Lime Scale Build-Up

The build-up of lime scale and other deposits can restrict water flow causing a hissing sound as water forces its way through the blocked sections. Hard water areas are especially prone to this situation. Regular descaling of your system can help control these noises.

Expansion Tank Problems

Your expansion tank is designed to absorb pressure increases from heating water in your house. However, when it gets waterlogged or fails to function properly, it can cause your pipes to make gurgling noises or even loud bangs in severe cases.

Sediment Accumulation in Water Heater

Over time, sediment tends to accumulate at the bottom of your water heater. As the sediment heats up, it causes the water above it to boil creating a rumbling noise. Regular flushing of your heater can help eliminate this problem.

Faulty Valves

Valves that do not fully open or close can also cause various kinds of noises as they prevent proper flow of water. If the noise is localized around a specific valve, then probably you have found the culprit.

Trapped Air Bubbles

Air bubbles trapped in the plumbing system can also create ticking or popping sounds. Releasing trapped air through system bleeding usually resolves this issue.

Vibrating Risers

Risers are the supply lines running between floors in houses. Sometimes, if these risers are loose or not well-secured, they vibrate when water passes at high velocity causing noise.

Active Sump Pumps

Sump pumps control water levels around your house’s foundation. If it is continuously working and pumping, it may direct large volumes of water through your pipes rapidly leading to noises.

Water-Saving Devices

Some water-saving devices may alter the flow patterns or pressure in your pipes, causing an odd noise. Pressure-reducing valves and low-flow fixtures are the usual suspects here.

Noise Reduction Techniques for Plumbing

Various plumbing noise reduction techniques such as the installation of air chambers (to prevent water hammer), insulation of all accessible pipes or installing anti-vibration clamps can be employed. While you can sometimes handle the preventive measures yourself, more severe issues might necessitate the expertise of a professional.

The Final Leaks

In a nutshell, plumbing noises have many causes which range from simple expansion due to temperature change to serious malfunctions like a failing expansion tank. Identifying the source is the first step to solving your problem. Whether you attempt DIY fixes or hire a professional, remember that ignoring these noises could potentially lead to serious damage in your home.
