Groaning pipes can be a real nuisance, especially when you're trying to start your day with a refreshing shower. The sound is often described as a loud, creaking or groaning noise, usually accompanied by a slight vibration in the pipes.
This noise is typically caused by the buildup of sediment and debris in the pipes, which can be exacerbated by old or corroded pipes. In fact, a study found that 75% of homes with older plumbing systems experience groaning pipes.
The type of pipes used in your home can also contribute to the problem. For example, galvanized pipes are prone to corrosion, which can cause the pipes to expand and contract, leading to the groaning noise.
If you're experiencing groaning pipes, it's essential to investigate the issue further to determine the root cause.
Causes of Groaning Pipes
Groaning pipes can be a real nuisance, but the good news is that most of the time, it's an easy fix. One common cause of groaning pipes is high water pressure, which can be indicated by a loud tuba-like sound. If your water pressure is set to over 80 psi, you may start to hear it, and ideally, you should aim for a reading between 40 and 60 psi.
Another possible culprit is a faulty toilet fill valve, which can cause a distinct moan coming from the pipes in the bathroom. If you suspect this is the problem, try turning off the water supply to each of the toilets in your home, then turn them back on one by one until the noise starts up again.
Sometimes, groaning pipes can be caused by air in the pipes, which can be remedied by having a plumbing professional bleed the air out of your pipes. This should fix the problem if that's indeed the cause.
If the groaning sound is accompanied by a toilet that backs up on occasion, slow draining sinks and tubs, and foul smells coming from your drains, it's likely due to a blockage in your pipes. In this case, it's essential to call a local plumber immediately to avoid a burst pipe and significant water damage.
Here are the common problems that could be causing your pipes to groan, moan, and whine:
- Your water pressure is too high.
- Your toilet fill valve is faulty.
- There's air in your pipes.
- There's a blockage in your pipes.
When the Problem Arises
So you've finally got your little one asleep, and you're craving a glass of water, but the sound of groaning pipes is making you hesitant to turn on the tap. Unfortunately, some water pipes can be quite loud and noisy when used.
The unwelcome din from your pipes is usually caused by a few common factors, including water hammering, loose piping, worn out washers, faulty main shut off valves, and worn out ballcock assemblies.
Water hammering is often the most common culprit behind noisy pipes. This occurs when water suddenly stops flowing, causing a shockwave that makes the pipes rattle and bang.
Here are some common causes of noisy pipes:
- Water Hammering
- Loose Piping
- Worn Out Washers
- Faulty Main Shut Off Valve
- Worn Out Ballcock Assembly
These issues can arise due to various factors, such as weather changes, clogs, or worn-out parts. It's essential to identify the root cause to fix the problem effectively.
Reducing Noise
An experienced plumber or heating engineer can diagnose the cause of the banging noise and make the necessary changes to stop it.
Fitting new valves that close slowly and a hydraulic shock arrestor can fix the problem of water hammer.
Checking plumbing pipework is fixed securely in place can help prevent movement and reduce noise in the future.
Some combi boilers are more prone to water hammer than others, which can lead to fine cracks in the manifold and leaks.
Common Issues
Groaning pipes can be a real nuisance, especially when you're trying to relax after a long day. One of the most common causes of groaning pipes is high water pressure, which can lead to water leaks, pipe damage, and wasted water if left unchecked.
If your water pressure is set to over 80 psi, you'll likely hear a loud tuba-like sound. Ideally, you should aim for a reading between 40 and 60 psi. If the high pressure is coming from the street supply, your plumber will need to install a pressure moderator to decrease the noise and mitigate potential damage to your plumbing system.
A faulty toilet fill valve can also cause groaning pipes. To identify the issue, try turning off the water supply to each toilet in your home and then turning them back on one by one until the noise starts up again.
Here are some common issues that can cause groaning pipes:
- High water pressure
- Faulty toilet fill valve
- Air in the pipes
- Blockages in the pipes
If you suspect a blockage in your pipes, it's essential to call a local plumber immediately, as it can lead to a burst pipe and significant water damage.
High Pressure
High water pressure is a common issue that can cause humming or vibrating sounds in your pipes. Ideally, incoming pressure should be about 50 PSI to prevent pipes from making noise and experiencing unnecessary strain.
Water pressure regulators, also called pressure-reducing valves (PRVs), are designed to reduce the pressure of the incoming supply. If your pressure seems inconsistent or higher than is comfortable, locate your main water valve and check to see if there is another device on the other side.
Loud banging sounds can be caused from water pipes moving due to much water pressure in the plumbing system. High pressure/PSI (pounds per square inch) can lead to other plumbing problems and issues with your water lines.
If your water pressure is set to over 80 psi, you'll start to hear a loud tuba-like sound. You can do a water pressure test if you are feeling particularly handy. Ideally, you should get a reading between 40 and 60 psi.
Here are some common signs of high water pressure:
- Humming or vibrating sounds
- Loud banging sounds
- Pipes moving due to high pressure
- Inconsistent or higher than comfortable pressure
If you notice any of these signs, it's a good idea to check your water pressure and consider installing a water pressure regulator to prevent damage to your pipes.
Loose Components
Loose components can be a major contributor to noisy pipes. A loose washer is a common culprit, causing rattling, whistling, or squealing sounds as water flows through the pipes.
Loose fasteners and hardware can also cause pipes to become noisy. Excessive wear on washers can lead to loose pipes, which can result in a range of unpleasant sounds.
Copper pipes are particularly prone to making whistling and squealing sounds due to their malleable nature. As hot water flows through them, they can expand and contract, causing them to rub against surrounding materials and create noise.
To prevent this issue, professional plumbers often pad copper pipes with insulation. However, if you're not ready to tear out your walls, you can try lowering the temperature on your hot water heater slightly. A few degrees can make a big difference in reducing the noise caused by expanding pipes.
Here are some common signs of loose components:
- Rattling, whistling, or squealing sounds from pipes
- Worn washers and loose pipes
- Copper pipes making whistling and squealing sounds
If you suspect loose components are causing the noise, it's essential to investigate and address the issue promptly. Loose components can lead to more significant problems, such as water leaks and pipe damage, if left unchecked.
When the Issue is a Hammer
A water hammer is a common issue that can cause loud banging noises in your pipes. It's usually caused by a small vacuum downstream when you shut off a faucet suddenly.
The noise is followed by a series of diminishing banging noises, which is a dead giveaway that you have a water hammer. If you don't hear the noise when you close the valve slowly, it's not a water hammer, but an air hammer instead.
Water hammers only occur when valves are closed suddenly, and they can be prevented by installing a water hammer arrestor in some situations. This device has a spring-loaded shock absorber that mitigates the force of the water and stops your pipes from making noise.
You can also prevent water hammering by shutting off the main water valve, turning on all taps, and draining the entire house. This will push air into the risers designed to prevent water hammering.
When you fill up the water again later, the air will help cushion the force of the water, preventing it from causing the pipes to rattle or hammer.
[Clogged]
Clogged pipes can be a real pain. The most common noise you'll hear when there's a clog is a sucking or gurgling noise, which is usually caused by a build-up of debris in your pipes.
Grease, food debris, and hair are common culprits that can cause clogs. Grease can build up in your pipes over time, even from small amounts of cooking oil or fats in bar soaps. Food debris, like mushy food on the bottom of your sink, can also cause blockages if you rinse it down the drain instead of composting it.
Hair is another major contributor to clogs, especially in sinks, showers, and bathtubs. To prevent this, it's a good idea to place a drain cover at the bottom and clean it after each use.
Tree roots can also invade your pipes and cause clogs, especially if you have trees nearby. These roots can expand and grow inside your pipes, causing major problems.
If you suspect a clog, you can try using an auger to snake the drain, but this may not be effective for clogs closer to the sanitary sewer line. Natural or enzymatic drain cleaners can also be used, but be aware that they won't do much for root growth.
Here are some common causes of clogs:
- Grease
- Food debris
- Hair
- 'Flushable' wipes (which shouldn't be flushed at all)
- Tree roots
