Things You Should Never Pour Down The Sink

Most of don’t even sit to think about if what we are pouring down the drain is okay or not for the pipes, the water system, or the environment. All we think about is, that we manage to get rid of it as fast as possible. And while this may be relatable, it shouldn’t be a common practice. Things we would have never thought were damaging may have been causing all of those annoying clogs all along. So, let’s see what we should never pour down the drain.

Oil or Butter

It’s important to know that pouring oil down the sink is probably one of the worst things you can do to your pipes. Things like oil, butter, and grease create thick layers of slime that stick and remain on the pipe. Half of all household drainage problems are caused by such sticky grease. This can lead to you having to unclog the sink. Not only that but such substances can pollute the environment and cause danger to animals and plants. That’s why we recommend pouring any remaining oil or grease you have in a jar that you can throw in the trash.

Kitty Litter

While it may seem like common sense to throw items such as wet wipes and kitty litter down the drain, it’s not where they are supposed to go. Things like this only cause harm to the pipes and clog the pipes as well as some serious damage. The worst that can happen is if you try to unclog the sink and the chemicals of the litter and wipes react with the chemicals in the product causing even more of an issue. So remember, no kitty litter or wipes down the drain!

When we say paint, we don’t mean water paints that are used for school projects. Some types of pain are considered toxic due to the high chemical content such as biocides. Such substances are a threat to the environment, animals and humans. So, if you have such pain leftover, and you’re wondering what to do with it, don’t go for the sink. Rather pour it in a small container and give it to someone who may be in need of paint or dispose of it in a specific trashcan.

Coffee Grounds

Who would have though that coffee grounds could be such a menace when it comes to kitchen pipes. However, according to plumbers these little, fine grounds can get stuck in the pipes and mix with all other types of waste. Creating a huge block over time. Instead of disposing of your ground in the sink. Use them for fertilizer.

Pills, drops and all other types of medication don’t pose a direct threat to your plumbing system and pipes. However, there are one of the biggest pollutants. While some doctors may advise you to throw away any expired medication down the drain or in the toilet, it’s not a good idea. These things contain a bunch of chemicals that are hard to be eliminated in the wastewater treatment plants. This means that the clean water you are getting back may have some pill chemicals.

All of us our guilty of pouring expired milk or milk we haven’t drunk down the drain. However, it’s best to avoid pouring such dairy products into your sink. Milk consumes a lot of oxygen, which means that when your sewer water reaches the sea or the river, the milk in it will make it harder for marine animals living to have a good oxygen flow in the water. And yes, there is oxygen in water, just in smaller amounts.

Cleaning Products

Cleaning products have a high chemical content. After all their job is to remove germs and dirt from various surfaces. While these products may not clog your pipes, they will for sure pollute the environment. Chemicals that manage to enter the water system, pollute the water resources. Try to use up all of your products, instead of throwing them down the drain and then recycle the bottles.
