Purging Air From Toilet/Shower Lines

I recently replaced the innards of the toilet in my master bath and have noticed that whenever the shower is running and the toilet is flushed, I hear a loud chattering noise in the pipes. I assume this is due to some air that has gotten into the lines.

Does anyone know of a solution to this?

Kris: welcome to the forums! What you are hearing is water hammer. Air does not stay in running water, but any that is trapped can cause the pipes that are not fastened well to vibrate. Installing water hammer eliminator will help. Google water hammer eliminator to see the different styles and mounting locations. If you need help, let us know.

My guess would be that it is a shutoff valve washer chattering. Make sure the valve is full open. If that does not help, remove the valve stem and check the washer, could be loose.
