What Your Plumbing Is Telling You: A Guide to Identifying Noises

What Your Plumbing Is Telling You: A Guide to Identifying Noises

Why does your home make strange noises, especially at night when it’s all quiet and you’re trying to sleep? No, your house is not haunted by a five-hundred-year-old ghost, and your building is not about to collapse.

The noises you hear are probably just your plumbing acting up and creating all these weird effects, says LRES Casselberry Management. Below, we explain why the pipes and plumbing fixtures in your home are making strange noises and what you can do about them.

  1. High water pressure (humming and vibrating sounds, water hammer)

If the water pressure inside your pipes is too high, you will hear strange noises from your plumbing. High water pressure causes pipes to hum and vibrate. You may also hear the sound of banging, something known as water hammers. Water hammers often happen when you turn a faucet on; the sudden rush of water hitting the pipe components is what causes the pipes to clang and vibrate.

Pipes will also clang and rattle if the flow of water stops abruptly as the faucet is turned off. To solve this problem, find the root cause of high-water pressure in your home. If the problem is from the city water supply, there is not much you can do. Installing a water pressure regulator or pressure-reducing valve (PRV) will help to even out the water pressure inside your pipes.

  1. Clogged water pipes (clanging and banging sounds, water hammer)

Sediment buildup inside water pipes, as a result of hard water or corrosion, can cause your plumbing to make strange noises. Because of their narrowed channels, water pressure inside these clogged pipes will be higher. Sediment can cause abrupt stoppage or slowing of water, resulting in sudden surges in pressure and the resulting water hammers.

The force of water hitting clogged sections inside the pipes can also knock pipes and pipe connections out of position, causing those loose sections to make noises. Mineral buildup in the air chambers of water pipes can cause strange noises in the system. To address these issues, you must deal with the root cause of the buildup within your pipes.

  1. Loose plumbing components (rattling, whistling, and squealing)

Loose components, such as fasteners and washers, can make strange noises in your plumbing. For instance, worn-out or loose washers might make a squealing noise as surging water forces them to rub against the other parts of the system.

Copper pipes also tend to make whistling and squealing noises as they rub against nearby drywall or the wooden features of your home. This is largely due to their malleability and ability to expand and contract quickly.

To fix annoying sounds from copper piping, insulate the pipes or reduce the temperature of your hot water slightly. To deal with noises from loose plumbing components, find the moving parts and replace or tighten them.

  1. Noisy water heater (clanging, hissing, rumbling, whistling)

A noisy water heater tank is a potentially life-threatening problem; it should not be taken for granted. If your water heater tank is making strange noises, water pressure and temperature levels inside the tank may be reaching dangerous levels.

This problem is caused by high rates of sediment buildup inside the tank, maybe as a result of hard water or corrosion. The accumulated buildup within the tank traps heat, causing the water inside the tank to constantly overheat. High temperatures from excessive buildup also cause the water heater tank to expand and contract erratically.

These are the reasons why your water heater tank makes strange noises. An overheating water heater is not only prone to leaks, but it is an explosion waiting to happen. To fix the problems, drain the water heater, ensure the TPR valve is working, and have a professional plumber check the heating element or anode rod.

  1. Clogged drain lines (bubbling, gurgling and sucking sounds)

A clogged or blocked drainage line is likely to make strange sounds. Your drains will also make strange noises if the vent stack is blocked. These sounds come from the trapped air inside the system. Not having a way to exit the pipes, sewer gases and vapors can force their way out through toilets, sinks, and floor drains.

The sounds you hear inside your home may come from the trapped water inside your drain lines pushing its way out through the onrushing water in your toilet. To solve this problem, avoid behaviors that allow items such as grease, food debris, paper products, etc., to enter the drainage pipes.

Also, get rid of the materials blocking your drain lines by hydro jetting the pipes. If there are tree roots within the pipes, you may want to remove the trees or set up tree root barriers.

Beyond fixing the strange noises in your plumbing, is there a way to stop this problem from happening? Yes, there is. A comprehensive plumbing inspection done annually by a qualified plumber will help you identify the potential cause of strange noises in your plumbing.

By finding these problems early, before they become a nuisance, you can stop them from degenerating into annoying sounds that keep you up at night. Yearly plumbing inspections also allow you to preempt other budding issues in your plumbing.

Why is the Plumbing Gurgling Under My Sink

Why is the Plumbing Gurgling Under My Sink.

A gurgling sound from your sink is a sign that the plumbing is not installed correctly or that there are issues with the sink vent. It can also signify that your home’s sewer line is blocked. How do these issues happen, and if your sink makes a gurgling sound when it drains, how do you solve the problem?

It is normal for water to make a splashing or swishing sound when it leaves your sink. But a gurgling sound coming from your sink is abnormal. When gurgling sounds come from the sink, there is also a chance that you will have a problem with sewer gases finding their way into your home, warns Castle Management.

Why is your sink making a gurgling noise

The three main reasons why the sink might make a gurgling sound when water flows into it are:

  • The sink is not vented
  • The sink vent is blocked
  • There is a blockage in the sewer line

The sink is not vented

Your home’s plumbing operates under the force of gravity and air pressure. When water enters the drain opening, the only way it can flow through the pipes is by displacing the air that is already in the pipes. Since water is denser than air, gravity can make it force the air inside the pipe downwards. This creates suction pressure behind the water.

When this happens, a zone of low-pressure forms within the pipe, creating a vacuum. Since vacuums do not generally exist in nature, air must enter the pipe to offset the imbalance in air pressure. If the pipe is properly vented, that air will come from outside the home through the vent. If the pipe is not vented, the air is sucked out of the P-trap, creating a gurgling sound.

Along with gurgling sounds from the drain, sewer gases may also escape from the drain opening and foul up the air inside your home. To solve this problem, you can install a vent under the sink after the P-trap. This can be connected to the central vent outside the home. It could also be a mechanical vent that sits under the sink and draws air from the surrounding area.

The sink vent is blocked

The pipe vent moves air from outside into the pipe and replaces air displaced when you flush water into the drain. But the vent can’t do this if it is blocked. A blocked sink vent is as good as not having a sink vent at all. The same problems when there is no sink vent happen when the sink vent is blocked.

Vents can get blocked if an animal dies inside it or gunk accumulates within the pipe. How do you know if your vent pipe is blocked? Several signs accompany this issue, including strange noises from the drain sink. Other signs to expect when a sink vent is blocked are slow drains and sewer gases finding a way into your home.

If you think your vent pipe is blocked, you need to clean it. Where the blockage is inside the pipes, this can cost between $100 and $200. The problem will only worsen if your vent pipe is blocked and not cleaned immediately. More debris can be sucked into the clogged pipe, making the problem worse and harder to deal with.

Blockages inside the sewer line

The sewer line that carries wastewater from your home to the municipal sewer lines is also connected to all the drains in your house. When there is a problem with the main sewer line, it can throw all the drains in the home out of order. A blocked sewer line can also manifest as gurgling sounds from the sink.

To know if the gurgling sound from your sink is caused by a blockage inside the main sewer line, check if all the sinks in the home are making this gurgling sound. Typically, all the sinks in the home will be affected if the problem is from the main sewer line. When this is the case, cleaning your sewer lines by way of hydro jetting is the only way to solve the problem.

What causes blockages in the main sewer line? There are many reasons why this can happen, but the more common ones are washing fats, oils, and grease into the drain; flushing food waste into the gutter; tree roots puncturing or growing around the sewer line, and corrosion inside the sewer line. Using chemical drain cleaners to clear your drain can also damage the main sewer line.

To conclude, if you hear gurgling sounds coming from your sink every time you flush water into the drain, you may be sure that your sink is not vented, the sink vent is blocked, or there is a problem with your main sewer line. To know the exact cause of the problem, you may want to have a plumber perform a sewer camera inspection.
