What Items Are Safe to Put Down Your Drains?

Schedule Now

It’s tempting to toss just about anything down the sink to get it out of sight and out of mind. Unfortunately, what you put down the drain might come back to cause bigger issues. In fact, putting anything down the drain you’re not supposed to can create large blockages in the system, potentially leading to inconvenient and costly problems with your plumbing system.

For this reason, it’s important to know what foods and liquids are safe to put down the drain versus ones that aren’t.

Foods & Liquids That Can Go Down the Drain

While there are substances that shouldn’t be tossed down the drain, there are actually many foods and liquids that can be put in the drain without any issues.

Soft foods

There are certain soft foods that can be put down the drain, as your garbage disposal has the capacity to easily break down these items. A few examples of this include:

  • Eggs without the shell
  • Pineapple without the skin
  • Bananas without the peel

While most soft foods that you can chew are okay to put down the drain, it’s important to remember that there are a few exceptions. Foods that expand with water, such as rice or pasta, should not be put down the drain, as they can expand and create blockages.


If it’s a non-toxic liquid, it can go down the drain.

Milk, coffee without the coffee grounds, juice, beer, dish soap, vinegar, wine, and more can be put down the drain. Even semi-liquid things like apple sauce, yogurt, and pudding can all be safely flushed down the drain.


Most vegetables can go down the drain, with the exception of fibrous vegetables.

Avoid vegetables like carrots, celery, artichokes, potato peels, fruit pits, bones, and corn husks. Ideally, scrap everything you can reasonably throw into the trash, and only small leftovers go down the drain.

Unsafe Items to Put Down Your Kitchen Sink

On the other hand, avoid putting these items down the drain:

  1. Grease, Oils, and Fats: Pour liquid grease into a container until it hardens, and then toss it in the trash. If you pour it into your kitchen sink, then the hardening will happen in your drain.
  2. Paper Towels: They are great for absorbing that spill, but they’ll keep expanding in your drain.
  3. Pasta: Always toss pasta leftovers in the trash. Pasta will gum your drain.
  4. Flour: Seems harmless, but flour mixes with the water in your sink to make a gooey paste.
  5. Medications: While medications won’t necessarily create clogs, they may end up in the ecosystem if dropped down the drain.
  6. Coffee Grounds: Grounds from coffee can easily expand when combined with water, which is why you shouldn’t throw them down the drain.
  7. Rice: Don’t underestimate the power of grains of rice to expand and create clogs in your drain.
  8. Eggshells: In addition to dulling your garbage disposal, the shells can attach to the sides of the drain and invite additional waste to join in.
  9. Potato Peels: Potato peels are incredibly starchy and can easily create clogs.
  10. Seafood Shells: Your drain can also become clogged if crab, lobster, or shrimp shells get stuck.

Keep your drains clear by also avoiding anything that is greasy, oily, fatty, sticky (like honey), expansive, fibrous, starchy, or hard.

What Is Safe and Not Safe In the Toilet?

Just like your kitchen sink, there are many items that shouldn’t be flushed down the toilet. Besides what typically goes down a toilet, the only thing that is safe to flush is toilet paper. Feminine products, flushable wipes, condoms, baby wipes, and other similar hygiene products can easily create blockages in your sewer line.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
