Plumbing noises may not signify much, or they may signify problems that require diagnosis and fixing. The source or cause of noise determines whether you need to do anything about it. Below are three main sources of these noises.

1. Drainage Pipes

Several parts of the drainage system can be noisy during operation or malfunctions. For example, the plumbing system requires efficient venting to function. Blocked vents interfere with air pressure control within the drainpipes, resulting in blocked drainpipes. If that happens, you might hear gurgling noises as waste struggles to flow into the drains.

Venting issues aren't the only problems that cause drain noises. Anything that blocks the drains and prevents efficient waste flow can cause drain noises. Hair, dirt, grease, and food remains are all culprits.

2. Water Supply Pipes

Noises in the water supply system arise due to many reasons. Below are a few examples.

Leaks

Water leaks can be noisy if the water drips onto a hard surface. For example, water dripping on a metal appliance can be noisy. You should suspect a water leak if you hear dripping noises but cannot identify the source. In such a case, you are probably dealing with a hidden water leak.

Hammering

Water hammer noises occur when something suddenly stops or changes the direction of high-velocity water. Consider a case of high-pressure water flowing to the taps. The rushing water will stop with a bang if you suddenly turn off the tap.

High Flow Rate

Your water pipes can be noisy even during normal flow if the water has high pressure and flowing at high velocity. In such a case, the noises come from the rush of water through the pipes and the pipe vibrations due to the rushing water.

3. Appliances and Fixtures

Lastly, the appliances and fixtures that form part of the plumbing system can also be noisy. Below are a few examples.

Water Heater

Water heater noises are common because the water heater metal expands with rising temperatures. However, the heating system can also be noisy because of sediment deposits in the tank. In such a case, you may hear popping sounds from the tank as trapped steam bursts out of the sediments.

Toilet

Phantom flushing is a common cause of toilet noises. The phenomenon occurs when the toilet flushes without anyone activating the flushing arm. Phantom flushes usually occur if water leaks from the tank into the bowl. The flush occurs once the water in the bowl reaches a certain volume.

Sump Pump

Sump pump noises can also be normal or indicative of malfunctions. For example, the sump pump has a motor that uses electricity to run, inevitably making some sounds. However, the pump's noises might increase due to clogging, wear, overwork, or mechanical damage.
