Ways to Prevent Kitchen Sink Blockages

Kitchen sink blockages are very common and the causes are usually the same – we should know, since we’ve been unblocking drains for over 30 years! Kitchen sinks in homes both old and new are subject to blockages. If you find that the water in your sink drains out slower than usual, it’s probably a sign that your drain is blocked.

The best part about kitchen sink blockages is that they are easy to prevent, if you take a step to make a little bit of effort.

  1. Stop pouring grease, fat and oil down the drain

What happens with the excess oils, grease and fat you pour down the sink after cooking, is that it cools down and begins to solidify. As they solidify, they coat your pipes and over time, can cause serious kitchen sing blockages that need the assistance of a professional plumber.

Either seal excess oils and grease into sealable containers and throw them in the trash, or wash down the small amounts of oils (such as those left on plates and bowls) down the sink with hot water and detergent so that it is broken up and won’t sit around in the pipes under your sink.

  1. Don’t wash food scraps down the drain

Food particles are a common cause of kitchen sink blockages, so avoid letting food scraps run down your drains at all costs. You can do this by purchasing a drainer plug that can be put on top of your sinkhole to collect any food particles or use a garbage disposal.

Foods to avoid especially include:

  • Banana peels
  • Rice
  • Pasta
  • Cereal
  • Coffee grounds
  • Egg shells
  • Potato skin
  1. Use a garbage disposal, but be aware of what you can’t put down there

Using a garbage disposal is a lifesaver for many and helps prevent potential blockages. These systems grind down food waste so that they can be safely washed away without causing a blockage. However, the garbage disposal is not the best place for every type of food waste.

You’ll want to avoid putting these types of food down there:

  • Fatty meats
  • Bones
  • Seeds and pips
  • Starchy and fibrous vegetables
  • Coffee grounds
  • Pasta and other noodles
  • Eggshells
  • Grease and fats
  1. Once a week, clean your drain

You should clean your drain regularly to help prevent blockages. To do this, pour a kettle of hot water down the kitchen sink drain. This will help to melt away ant grease that has built up around your pipes. It may also help loosen any food particles that have stuck to your pipes.


These are some simple steps you can take to keep your kitchen sink working at it’s best. However, if your sink is past the point of prevention and you’re in need of help getting it unblocked, call a professional who can safely clear your drains using safe, up-to-date equipment.
