Calcium deposits can badly clog these holes, restricting the flow of water from the tank to the bowl. Some toilets have a siphon jet at the bottom of the bowl which can also be clogged by the calcium in the flush water. As you remove calcium deposits from the toilet bowl, don't forget to remove the one clogging rim holes and the siphon jet.

Calcium deposits are formed when water containing dissolved minerals evaporates on stone surfaces, leaving behind the mineral residue. These deposits often appear as white or off-white crusty build-ups, giving an unsightly and dull appearance to the stone. Common types of calcium deposits include efflorescence, limescale, and hard water stains.
