What should I do if the toilet seat makes a noise when it is turned over too tightly?

Method 1: Find the screw cap of the toilet seat, remove it with a live handle, and replace it with a new one.
Generally, the position of the screw cap is not easy to find, some are in the bright place, and some are in the dark place. The screw cap in the dark, on the side of the tank in the toilet, open the lid. Reach in with your hand and touch it upwards and towards the water tank. You should be able to touch it, but you can't see it.

Method 2: When replacing the toilet seat, just remove the fixing bolts at the back of the toilet, and then operate in the opposite direction during replacement and installation. Most toilet lids are size-independent, and you only need to adjust two bolts when installing. However, it is also necessary to measure the size, the distance of the screw holes, the width and length of the toilet cover, and then buy a new toilet cover for replacement.

Method 3: In addition to the above two methods, it is recommended to find a professional for replacement.
