Rim holes are a series of small holes located around the inner rim of a toilet bowl. They distribute water evenly from the tank during flushing, helping to rinse the bowl thoroughly and improve the efficiency of waste removal. Rim holes play a vital role in maintaining toilet cleanliness, preventing buildup, and ensuring effective flushing action. Over time, rim holes can become clogged with mineral deposits or debris, which can reduce flush performance. Regular cleaning, including using a brush or specialized cleaner, helps maintain clear rim holes and optimal flushing.
