Common causes of clogged drains
Bathroom sinks, showers and tubs collect hair and soap residue that bind together over time. Kitchen drains clog when grease, fat and cooking oil cool and stick to the pipe walls, especially when combined with food scraps washed down a sink that has no garbage disposal.
Toilets clog from wipes, hygiene products, cotton balls and large amounts of toilet paper. Small objects such as jewelry or toys can lodge in a trap. In outdoor drains and sewer lines, tree roots can grow into pipes in search of moisture and nutrients.
