3 Tips for Dealing With the Most Common Plumbing Noises

3 Tips for Dealing With the Most Common Plumbing Noises

Strange sounds are typically a bad omen. Plumbing problems are also associated with a specific set of sounds, like whistling or rumbling. Of course, these sounds aren’t a prerequisite of plumbing issues (hissing may indicate a snake problem too…). If snakes and other intruders are absent, though, the sounds could be coming from the pipes in your home.

Here’s what you need to do in that case:


Whistling pipes suggest low water pressure. If the whistling is coming from your toilet, there’s likely an issue with the toilet fill valve. This valve controls the flow of water into your toilet’s tank, and the fault causes a leak. You could try adjusting the valve, but if that doesn’t work, then contact a plumbing service to evaluate it.

If the whistling is coming from a sink, try turning the shut-off valve off and on (the main valve is typically in the basement or outside the house). Debris or air could be responsible for low water pressure. Turning off the valve drains the pipes of water, and turning it on causes water to flow. Both can drain any air and dislodge any debris in the pipes.


A hissing sound is the opposite of whistling: it indicates high water pressure. The hissing is a sign of the pipes under stress, which is caused by high water pressure.

To lower the pressure (short of putting a hole in your pipes, which is unequivocally a bad idea), adjust the pressure regulator. If you don’t have a pressure regulator installed, contact a plumbing service to install it and solve the issue.


Banging sounds or thuds are typically signs of loose piping or high water pressure. You can determine what they indicate by figuring out where the sound is coming from. Thuds while closing a faucet indicate high water pressure. Turning the faucet off is harder due to the pressure, and this stress causes the sound. As with whistling, a pressure regulator can solve the thuds.

If you hear the thuds from around your pipes, the piping is probably loose. Pipes will expand and contract as the temperature of the water passing through them changes. These periodic expansions and contractions will cause loose piping to move and hit their surroundings. Fixing this requires securing your piping.
