The problem of a toilet that makes a gurgling sound can be approached by checking the stopper ball and making sure it is centered on the valve seat inside the tank. You may need to loosen the screw on the guide of the lift wire and manipulate a little bit. Once this is accomplished, tighten the screw. If this doesn’t fix the gurgling toilet, take a close look at the valve seat and touch it to see if there are signs of pits, corrosion and roughness.
