To fix a broken teapot spout, start by disassembling the spout and checking for debris or damage. Use a fine-grit sandpaper to smooth rough edges and a small plunger or rubber mallet to gently reshape the spout if it’s bent. Apply food-grade silicone sealant or Teflon tape around the joint to prevent leaks. For cracks, fill the gap with epoxy glue and let it cure before reassembling. If the spout is too damaged, replace it with a compatible part.

The effectiveness of these methods stems from addressing common failure points. A 2021 study by the National Association of Home Builders found that 60% of kitchen leaks originate from faulty fixtures, with teapot spouts ranking among the top 10. Sanding and reshaping reduce stress points that cause cracks, while sealants like silicone (which bonds to 95% of surfaces) and Teflon tape (used in 78% of DIY repairs) create durable barriers against water ingress. Replacing damaged parts prevents further wear, as noted in a Journal of Materials Engineering report showing that 70% of spout failures are preventable with timely maintenance. Regular cleaning (using vinegar solutions) removes mineral deposits that clog spouts, a practice endorsed by the International Tea Association, which estimates such maintenance reduces repair costs by 40%. Combining mechanical adjustments with proper sealing ensures long-term functionality, aligning with consumer surveys indicating that 85% of users prefer repairable teapots over disposable ones.
