3 COMMON REASONS WHY YOUR PIPES ARE MAKING HIGH PITCHED PLUMBING NOISES

It can be very alarming when strange, unexplainable sounds start coming from your pipes. In all our years of plumbing, we’ve definitely heard our fair share of odd pipe noises: groaning, creaking, scraping, and even screeching.

Any noise that isn’t common is cause for concern, but one of the noises that can be quite concerning is high-pitched squealing. Usually, when pipes start emitting high-pitched noises similar to squealing or screeching, there’s a good chance that something is seriously wrong.

The beauty of categorizing these odd plumbing sounds, however, is that they can give us valuable insight regarding the potential pipe issue. For instance:

High-Pitched Screeching or Whining While the Water is Running

Pipes Are Making High Pitched Plumbing NoisesIf someone turns on a faucet or a shower and the pipes start screeching in protest, there’s a good chance it’s due to one of two possibilities. In some cases, the pipes only shriek in soprano for a few seconds before falling silent. In other cases, unfortunately, the high-pitched sounds don’t stop.

Either way, if this is happening while the water is flowing, it’s either because of a.) the water pressure, or b.) a loose section in the faucet or valve.

When water flows rapidly through a small opening or past an obstruction, it causes vibrations. If there’s an area or section that’s loose, these vibrations can cause the parts to emit a shrill sound. In faucets, something as simple as a slack washer or untightened screw at the base of the faucet can result in high-pitched screeching due to the tremors.

Alternatively, if the water pressure is higher than what the pipes are used to, the same shrill sound can occur. Heavy water pressure coupled with a small opening can result in intense vibrations and, consequently, high-pitched noises.

Thankfully, this situation can easily be fixed by lowering or moderating the water pressure.

High-Pitched Squealing When the Toilet Flushes

As mentioned earlier, water pressure or loose parts are usually the culprit behind all that shrieking coming from your pipes. In the case of toilets, however, there is another possible explanation aside from unbalanced water pressure.

Shrill sounds from a toilet can often indicate trouble inside the tank—specifically a faulty washer in the ballcock assembly. If this is the case, we recommend replacing the entire valve stem instead of just the washer to guarantee that all parts are compatible and fully functional.

Shrill Sounds Without Water Flowing

It’s a little more difficult to diagnose the problem if there are high-pitched sounds coming from your pipes even when they’re not in use. Unlike in the previous instances, the sounds can’t be attributed to vibrations caused by running water. Ergo, there’s a fair bit of guesswork required in this scenario.

In cases such as these, one of the more common reasons for the shrill noise is due to blockage in the drain vent. For toilets, there may be a problem with the refill devices in the tanks. But while these are the more common reasons, there’s no way to tell for sure unless you contact a plumbing expert to give you a professional diagnosis.

Not sure if it’s time to call an emergency plumber? Here is a list of reasons plumbing issues to look out for!

We understand that hearing your pipes shrieking can be quite alarming. Rest assured, there is a logical explanation behind it and a perfect solution for it. Rather than assess the problem and then attempt to fix it yourself, we highly recommend calling a plumbing expert to handle the whole situation. This will save you time, money, and a lot of stress.
