: Angie,
: Your Titanic toilet is leaking at the flapper. Replace the flapper with a good quality 5 year flapper, and then if it still makes noise, replace the fill valve (ballcock) When replacing the fill valve, get a new supply tube.
: Noises like you mention are caused by loose rubber washers. (fill valve) The fact that the noises occur throughout the day, indicates that the water level in the tank is dropping , (leaking flapper) Terry

: Angie:--Terry Love has furnished you first class advice on your TITANIC problem. He did however overlook a very very important thing.
: Untill the repairs have been completed on your toilet, you must insist thst all users wear a life jacket and carry a flare gun...Ahrmand

: And even though the toilet sounds like a fog horn, don't get the idea that the sound will keep icebergs away. I've seen icebergs smash right into toilets at night. I would keep the night light on, it could get rather messy.
