https://bmwplumbing.net/2018/08/01/why-is-my-toilet-making-a-weird-noise - At BMW Plumbing Inc., we are providers of some of the best plumbing services in Northbrook. When the refill valve lets water into the tank, it creates a running sound. This noise should only last for about 30 seconds after flushing ends. If the running sound continues to occur, there is likely a leak between the bowl and the tank. Contact us if you need help fixing this problem. You may hear a sound that many refer to as a “water hammer.” Gurgling sounds come from the drain pipe rather than the toilet itself. It is usually a sign that the drain pipe is partially blocked or that something is blocking its vent.
