Plumbing Question 14
Question:
Why is there a loud droning noise every time I flush my toilet?
Answer:
By loud “droning noise,” I am assuming when you flush, the pipes are making a groaning or shaking sound. This is called “water ramming” or “air hammering.” It is caused usually by a leak drawing air into the line and forming an air bubble which bounces around inside the pipe and causes noise. Make sure the shut off valve under the toilet is fully open and check around the house inside and out for the slightest drip. This is where the air is entering the system. You can also install an “Air Chamber”, which is essentially a piece of copper pipe about 18″ long that is capped. This allows the air bubble to enter this dead end and dissipate.
