Scary Sounds a Toilet can Make and What they Mean

Wait — did you hear that? You know, that strange hissing noise coming from your bathroom! No, it’s not a rattlesnake (thank goodness), but it seems to be coming directly from your toilet! Although you might feel a sense of fear, there is an explanation for that scary sound. Not sure where to begin? We’re here to help:

Delayed Flush

When you flush your toilet, the water in the bowl should empty fast and then replenish quickly. Of course, when there’s an issue with your “throne,” then a simple flush will turn into an episode of watching paint dry.

If the water in your toilet bowl begins to empty slowly, that means that the holes under the rim are clogged. While this problem is on the quieter end of the spectrum, you will hear your toilet flush a few minutes after you’ve stepped out of the lavatory.

Indeed, there are some ways you can take care of this issue on your own, but if the “procedure” isn’t completed correctly, then it could lead to even more problems down the road. The best solution? Contact Pipe Wrench Plumbing, Heating & Cooling, Inc. the minute you notice a slow flush and a member of our team will take care of it on the spot.

Supply Line Trickling

Oh, that dreaded hissing noise — where could it be coming from? Of course, you could check every square inch of your toilet, but it may be impossible to find. However, if you happen to look inside the tank, then that’s where the problem resides. Believe it or not, the hissing noise is caused by water dripping from the supply line in your tank.

Before you rip through every square inch of the tank, it’s important to check the following parts, first:

  • Float

  • Refill tube

  • Ballcock


If you perceive any of these parts to be slightly “off,” then it’s essential to have the issue taken care of right away. If you happen to delay a repair, not only will it help the hissing linger, but also has the potential to diminish the quality of your toilet.
