10 Things You Should Never Put Down Your Drain

10 Things You Should Never Put Down Your Drain

It can be easy to think of your sink’s drain as a catch-all way to get rid of your garbage and food waste. However, maybe you should start taking a second to think about what you’re putting down there. Even if you have a garbage disposal, your drain can’t handle everything you may be throwing at it. We’ve put together a list of things you should avoid putting down your drain in order to avoid future plumbing problems.

1. Pasta and Rice

Pasta, rice, and other starchy foods can wreak havoc on your plumbing if you send them down the drain. These foods will continue to swell once they are in your pipes, causing a clog or causing your pipes to swell. They can also get stuck in your garbage disposal’s blades, causing even more problems down the road.

2. Eggshells

Eggshells are brittle enough that many people wouldn’t hesitate to dump them down the drain and let the garbage disposal do its thing. But eggshells can clump together when they get wet, causing more clogs in your pipes. Instead of putting them down the drain, try sprinkling them into your garden for some extra calcium.

3. Coffee Grounds

Another culprit that appears tiny and innocent, coffee grounds can be a major troublemaker for your plumbing. Even when it’s finely ground, coffee grounds can accumulate in your plumbing and are a common cause of blockages.

4. Medicine

This one won’t necessarily cause you plumbing problems, but it will give the environment more trouble than its worth. Prescription medications commonly end up in waterways and groundwater, harming wildlife and livestock. The FDA recommends dropping off unused medicines at your local drug drop-off site, which can be found here.

5. Cooking Oils and Animal Fats

Animal fats, like bacon grease, solidify at room temperature, so pouring it down the drain when it’s liquid isn’t a good idea. It will solidify and immediately clog your pipes when it cools down. Cooking oils like olive oil and vegetable oil remain liquid at room temperature, but can easily combine with other debris to cause clogs in your pipes. Oily foods like salad dressings and mayonnaise can do this, as well.

6. Paper Towels

While it’s easy to think that paper towels are sometimes thin enough to easily dissolve, that’s not the case. Paper towels are biodegradable, but it takes longer to break apart than some might think. It will cause blockages in your pipes long before it breaks up.

7. Flour

In large enough quantities, flour can clump together with water and lead to some serious clogs when it goes down your drain. It will coagulate and harden, leaving it caked to your pipes until it builds up enough to stop the flow.

8. Fruit Pits

Small or large, fruit pits are tougher than your garbage disposal’s blades. These blades aren’t sharp or strong enough to break apart a fruit pit and you’ll likely damage or break your garbage disposal entirely, even with small pits. Fruit pits can instead be composted.

9. Bleach

Bleach won’t cause problems on its own, but be careful when you pour bleach down the drain. If you’ve recently used a cleaner on your sink that contains ammonia, adding bleach will cause chloramine gas to form, which is extremely dangerous to inhale. Before you pour bleach down the drain, make sure that no one has recently used a cleaner that contains ammonia.

10. Banana Peels

Banana peels are soft, so you might think that the garbage disposal can handle them. But because they’re a softer texture, the blades can struggle to cut them up adequately. Stick with the regular garbage for banana peels.
