2. Noisy toilet
Many things can cause a noisy toilet. If the noise comes after flushing, it could be due to a dirty or corroded seal in the toilet fill valve. Check the toilet fill valve and clean it – if that doesn’t work, replace it, and it should resolve the issue.
A gurgling sound could indicate a blockage in the drain. Plunge the toilet to unclog it. If that doesn’t work, use a toilet auger to snake the toilet. Alternatively, check the vent stack, and if you find any debris, clear it and flush it.
