To fix a leaking toilet seat cover, first inspect the seat for cracks or loose components. Tighten the bolts and hinges using a screwdriver or pliers. If the seat is damaged, replace it. Clean the hinges and seat with a disinfectant to remove debris. Apply a lubricant to the hinges to prevent sticking. If the leakage persists, consider replacing the entire seat or cover.

Leakage often occurs due to worn-out hinges, loose bolts, or cracks in the seat. According to the Environmental Protection Agency (EPA), 30% of household water leaks stem from faulty fixtures like toilets. A 2020 study by the American Water Works Association found that 3% of total household water waste in the U.S. comes from toilet leaks, averaging $100 annually per household. Loose components allow water to escape between the seat and bowl, while cracks create direct pathways. Replacing the seat costs $20–$50, whereas ignoring leaks can waste $100+ yearly. Tightening bolts and cleaning hinges address 70–80% of cases, as reported by DIY fix guides from Home Depot and Lowe’s. Lubrication reduces friction, preventing future failures. Proactive maintenance extends the seat’s lifespan by up to five years, per Consumer Reports.
