1.Going In – Open the tank of your toilet take a close look at the various parts. First, check the ball cock – the valve linked to the large plastic ball that floats on top of the water in your tank. If the noise is coming directly from the valve or you can see obvious issues, the ball cock likely needs to be replaced. Sometimes, it needs only basic cleaning, which you should do first before running out to buy a new part. It also possible that the tank flap is having issues. Look for a small cone in the hole at the base of the tank. Press down on it to see if the sound stops. If it does, the tank flap likely needs replacement.
2.Turn off the Water Supply – Before doing any more, turn off your toilet’s water supply. Do not worry – you should not need to go hunting for the valve. It is most often located next to the toilet on the floor of your bathroom.
3.Replacing Your Parts – When replacing any parts for a toilet, always remove the old part first and bring it with you to the hardware store. Almost all toilets have slightly different parts that may not match up universally. By having the part you need, you can give it to an expert in toilet repair and they can quickly find the right replacement.
4.Careful Replacement – Most of the time, replacement simply involves unscrewing or removing the part and placing a new one in place. However, if you own a low flush toilet or a specialty design that does not have the same parts or layout of a traditional tank-based toilet, you may need the help of a professional to avoid any unwanted accidents or issues in the replacement process.
Ideally, the entire process should only take the better part of a couple hours, including the time it takes to go to the hardware store and purchase your replacement part.
