According to the Cleveland Clinic, the average person takes about seven trips to the bathroom daily, with most being uneventful.



However, visiting the bathroom will put a little extra pep in your step if your plumbing pipes make noise after flushing toilets in your home. The loud sounds these pipes make may even scare you when you aren't expecting them.


So, what causes this plumbing issue? Before scheduling a plumbing repair in Cleveland, OH, determine what can create all this commotion when you flush your toilets.


Water Hammers

Many Cleveland, OH, homeowners suffer from so-called water hammers, which make thunderous noises every time a toilet is flushed. Some homes also have loose pipes in their plumbing systems that amplify these sounds.


Here is how a water hammer forms:

  1. A person flushes a toilet, opening a valve enabling water to flow into its bowl.
  2. This valve remains open until the toilet finishes flushing, closing abruptly when its bowl fills.
  3. A pressure surge, known as a water hammer, forms when the valve closes.
  4. A water hammer travels through plumbing pipes quickly, making a loud noise.
  5. Loose and/or unsupported pipes make a water hammer noisier.

Water hammers are relatively common in homes, but can still be jarring when pipes make noise after flushing toilets.


Air in the Pipes

If you don't use a toilet for days, or if your home experiences a sudden change in water pressure, air might build up in your plumbing pipes. This air can become trapped in your plumbing system until you finally flush a toilet, allowing it to escape.


You can typically tell when this happens as it produces a loud noise. You will often hear a whistling or whooshing sound when air is trapped in pipes, causing noises after you flush your toilets.


Clogged Pipes or Sewer Line

If your plumbing pipes make noise after flushing toilets, investigate the possibility of clogged pipes or a backed-up sewer line. You will want to address this problem as soon as possible since it can gradually worsen.


When you flush a toilet while there is a clog in a plumbing pipe or sewer line, it creates back pressure within your system. This can cause bubbling or gurgling sounds.


Initially, you might suspect your toilet is clogged and attempt to clear it with a plunger. However, the issue is likely to be with your plumbing pipes or sewer line, so it's best to call a local plumber to address it.


Blocked Vents

Your home's plumbing system has vent pipes that ensure proper airflow. If they become blocked, you may create a vacuum when flushing a toilet. Just like clogged pipes and sewer lines, blocked vents can result in gurgling sounds when toilets are flushed.


If your pipes make noise after flushing toilets and you cannot determine where else it could be coming from, don't hesitate to ask a professional plumber to inspect your vents for blockages.


High Water Pressure

Homeowners in Cleveland, OH, often recognize the potential dangers of having low water pressure in their homes, but they overlook the fact that high water pressure can also be problematic. It could be why your plumbing pipes make noise after flushing toilets.


If your home's water pressure is too high — a common issue in Cleveland and other parts of Northeast Ohio — it could cause your pipes to vibrate excessively when flushing toilets. These vibrations sound louder than you might imagine and can potentially damage pipes over time.
