Protect Your Plumbing: Discover What Should (and Shouldn’t) Be Put in Your Kitchen Sink
Introduction
Kitchen sinks are the hub of your home’s plumbing system. It handles all sorts of food waste, grease, and debris. However, not everything that goes down the kitchen sink is supposed to. Some materials can damage your pipes and even clog them. This blog post will cover what should and shouldn’t be put in your kitchen sink.
What Should Be Put in Your Kitchen Sink
Foods
The food scraps that are small and can easily be broken down should be put into the kitchen sink. Soft and cooked vegetables or fruits scraps won’t damage the piping, and the garbage disposal will quickly grind them into tiny particles.
Liquid
You can safely pour liquid down the kitchen sink with or without a garbage disposal. Liquids such as leftover soup, juice, milk, water, and coffee will pass through plumbing without harm.
Dish Soap
Dish soap is safe to pour down the kitchen sink. It does not harden or leave any residue that could clog the pipes.
What Shouldn’t Be Put in Your Kitchen Sink
Grease and Oil
The rule of thumb: never pour grease down the kitchen sink. Liquid grease can quickly harden and clog the pipes. Avoid putting grease or oil from cooking pans, deep fryers, or kitchen grills down the sink. Always properly dispose of it in the trash.
Coffee Grounds
Coffee grounds can settle in your pipes and build up to form a blockage. Instead, dispose of them in the trash, or better yet, use them as compost in your garden.
Bones or Seafood Shells
The garbage disposal can’t handle large and solid food waste that can’t easily be grinded, such as bones and seafood shells. These items can also damage the blades of the garbage disposal. It is best to put them in the trash.
Produce Stickers
Produce stickers on fruit and vegetable skins can easily stick to your pipes and cause blockages. Take them off and put them in the trash before washing produce.
Conclusion
Knowing what you can and can’t put down your kitchen sink is essential for protecting your plumbing and preventing clogs. Be mindful of what you allow down the sink, and remember to dispose of anything that doesn’t belong in the trash instead. By following these simple rules, you can save a significant amount of hassle and some considerable plumbing expenses.
