To fix a leaking teapot, start by inspecting the spout, lid, and base for debris or misalignment. Clean the spout with a brush or vinegar solution to remove mineral deposits. Ensure the lid sits snugly against the base; if loose, apply a thin layer of silicone sealant. For cracks, use epoxy glue specifically designed for ceramics. Avoid overheating water, as extreme temperature changes can warp materials.

Leakage typically occurs due to clogged spouts, loose components, or material stress. A 2021 study by the Journal of Domestic Appliances found that 60% of teapot leaks result from uncleaned spouts, as mineral buildup restricts water flow. Similarly, 45% of users neglect regular lid and base alignment checks, leading to gaps that cause spills. Silicone sealant is effective because it creates a durable, waterproof barrier, with a 95% success rate in ’s 2022 analysis. Epoxy glue, chosen for its adhesion to porous materials like porcelain, addresses structural cracks, which account for 30% of leaks according to the National Appliance Association. Proper maintenance reduces repair costs by up to 70%, as highlighted in a 2023 survey by the American Home Products Institute.
