What is Safe and What is Not Safe to Put Down the Sink Drain?

In addition to liquids, other substances should not be poured down the drain. Chemicals and solvents can stick to the pipe walls and erode its surface. Even flushing large volumes of water with liquids will not prevent damage. And if the damage is already done, it will cost money to repair. Sticky items like tissues and cat litter should never be poured down the sink drain. They can become stuck inside the pipes and cause a large repair bill.


If you’re wondering whether ammonia is safe to put down the sink drain, you’ve come to the right place. This chemical contains both positively and negatively charged hydrogen and nitrogen ions. It has a pH level of 11 and can safely be flushed down the drain. However, it should never be mixed with other products or thrown into the garbage. It must first be neutralized in water before it can be flushed down the sink drain.

Many sinks and tubs become clogged by grease and soap residue from hair and soap. To solve this problem, you’ll need a cleaning solution that will dissolve these substances and loosen the blockage. The chemical ammonia is commonly found in commercial cleaning products, but it can also be used on its own to clean clogged drains. When used correctly, it can even be used to clean septic tanks.

However, if you’re not sure whether or not ammonia is safe for disposal, you’ll need to consult a professional. There are several methods to dispose of ammonia, including neutralizing it, pouring it down the sink drain, and throwing the container in the trash. Remember, ammonia is a hazardous chemical even in small quantities, so it’s best to properly neutralize it first before flushing it down the sink drain.


Various types of liquids, vegetables, and non-fibrous items can go down the sink drain, but it’s best to be extra careful when disposing of these items. Not only do they damage your plumbing, but they are also harmful to the environment. Read on to learn about what you should never put down the sink drain. Then, you can avoid causing a clog by following these steps.

To avoid clogging your drain, you should never put eggshells or other egg-based objects down the drain. Eggshells have sharp edges and can collect other things coming down the sink drain. Grease can stick to pipes, just like grease does in the street. Similarly, other oil-based products like cooking oil, salad dressing, and fat should never go down the drain.

Cooking oil should never be poured down the sink drain. Unlike liquid oils, cooking oils solidify and form Crisco or lard. These chemicals may clog pipes and endanger public and worker safety. Always store cooking oils in a container and wipe them off with a paper towel. Dispose of them in the trash can. But what about oil? It’s a good idea to store it in a sealed container.

Cat litter

Cat litter can clog your pipes. Unlike toilet paper, which disintegrates upon contact with water, it can swell and clog drains and sinks. If you want to avoid clogging your pipes, you can use a toilet snake to break up clumps of cat litter. Using a snake will loosen the clog so that you can clear it using mechanical methods.

However, there are some situations when cat litter can be flushed down the drain. First, it can clog drains because it expands and clumps when wet. As a result, water cannot flow through a clogged drain. Furthermore, cat litter adds solid waste to the septic tank. So, you must avoid flushing it down the drain.

Cat litter can also clog pipes due to its clay content. It contains high levels of bentonite clay, which hardens in contact with water. Therefore, it can be extremely difficult to remove once it has solidified. If the solidified cat litter is not removed immediately, it may clog the pipes, requiring water jetting or removal of the blocked pipe. This can cause serious plumbing problems.


While you might think that you can safely dispose of all unused or outdated medications down the sink drain, that is not the case. These medicines can contaminate water supplies, causing a chain reaction that causes them to clog and harm aquatic life. Ultimately, this can also lead to health issues for humans, so it is best to properly dispose of all medications and avoid exposing our community to the chemicals they contain.

In order to dispose of unwanted medicines properly, you should always place them in a plastic bag and mix them with something foul tasting. This will make them less appealing to children, as well as make them difficult to identify by other people. To make this process easier, you can crush and mix the pills with sawdust or cat litter. You can even mix them with coffee grounds. You should then store the mixture in a sealed trash can.

While most over-the-counter medications are safe to flush, you should never flush prescription medications down the sink drain. Not only will this result in the waste water flowing down the drain, but it will also expose the medications to your family. Children and pets can also be at risk, especially if you do not flush them properly. In addition to the above risks, flushing medicine down the sink drain will protect your water supply by preventing the medications from being discovered by your children and pets.


First, if you’re using a garbage disposal, be sure to empty your waste basket before pouring eggshells down the sink drain. Eggshells can block the garbage disposal’s blades, leading to clogs. You can compost them or use them for other purposes, such as fertilizing plants. In addition, eggshells are not good for your sink’s drain because they can attach to other food particles, such as coffee grounds. Finally, do not put cooking oils down the drain. They can thicken and clog over time, making the sink drain much slower and harder to clear.

Though eggshells don’t cause immediate damage to the garbage disposal, they may clog your sink. Once a clog has developed, it may be necessary to replace the entire sink or dispose of the clogged portion. This will depend on the type of clog and how far down the sink it is. Eggshells are also hard to break down, so you can’t simply toss them into the garbage disposal and hope for the best.

Another way to dispose of eggshells is to grind them up and run them through the garbage disposal. Eggshells, like other types of food scraps, will create sand-like particles and stick to the pipe walls, slowing the drain and causing a clog. Unfortunately, manufacturers can’t seem to come to a consensus on this issue, and some do recommend putting eggshells down the sink drain.

Sticky materials

While putting nuts, peanut butter, and other sticky materials into the garbage disposal can be convenient, the problem arises when you put them down the sink drain. These materials expand when shredded and can block the drain. Potato peels are another example of sticky materials that should be put into the compost pile instead of down the sink drain. In addition to nuts and peanut butter, rice and pasta should also be disposed of properly.

When you want to dispose of a particular material in your sink, be sure to separate it first. Certain materials can cause problems for the plumbing, such as paint and solvents. Although they are readily available in your local stores, they can harm your plumbing if they are poured down the drain. Sticky rice and flour can also clog drains and fill disposal traps. And last but not least, paint and other sticky materials should never be put down the sink drain. They pollute the environment and cause your pipes to clog.

Some cleaning products are liquid. Many of them contain harmful chemicals, phosphates, and antibacterial agents. These compounds are not filtered out by water treatment facilities. Toilet paper and other paper products also contain harmful chemicals. Always read the label to be sure they are safe to flush. If in doubt, consult a professional plumber. If they can’t diagnose the problem, consider putting them in the trash instead.

Coffee grounds

The question is: Is it safe to put coffee grounds down the sink drain? Half of the population advocates for it. The grounds’ grittiness helps to clear pipes and remove stuck food debris. Others suggest that the grounds can deodorize the drains. However, the truth lies somewhere in between. Here’s the scoop on whether or not coffee grounds should be put down the sink drain.

Putting coffee grounds down the drain is a no-no. Ground coffee sticks to the inside of the pipes. Pouring vinegar down the drain can help slow the clogging process, but it won’t prevent deeper clogs from forming. A more effective method is to place coffee grounds in the compost pile or make garden fertilizer. There are two main types of coffee grounds: natural and synthetic. Both types can clog the drain, but they’re safer to use than neither.

While coffee grounds aren’t the primary cause of kitchen drain clogs, they can clog the pipes. They mix with fatty substances, such as oil and food waste. These materials eventually form a thick layer on the pipes, clogging them and requiring expensive repair work. Additionally, used coffee grounds can stick to the grease and slow the drain. To avoid this, make sure to dispose of the coffee grounds carefully.
