Dumping leftovers directly down the sink may provide temporary convenience, but in the long run it can cause blockages or damage to the pipes. The health column of the US MSN site has summarized a few things that should not be poured down the sink below.
1. Rice
The rice after being soaked in water will swell and stick together to form lumps, clogging the pipes. After drying, cleaning is also very difficult.
2. Coffee grounds
Coffee grounds contain substances that are insoluble in water, have a high viscosity, easily adhere to other substances in the drain, and are difficult to be melted by water. Pouring coffee grounds down the pipe, this substance will accumulate, cling to other objects in the pipe, leading to difficult-to-flow flow and clogged drains.
3. Eggshell
Broken eggshell crumbs are difficult to pick up, so many people have a habit of flushing them down the sink. Eggshells may seem fragile, but it can wreak havoc on plumbing.
Wet eggshells that stick to the pipe after drying will be very difficult to remove. Over time, they will form a lump that blocks the flow of water, leading to clogged drains. What you should do is throw the eggshells in the trash.\
4. Noodles
Starchy foods can swell a lot on contact with water, clogging pipes. You can try pouring hot water, or a mixture of vinegar and baking soda, down the drain to improve the problem of clogged drains caused by noodles. The best way to avoid this clogged drain is not to pour noodles into the sink.
5. Grease
The oil left in the pan after cooking will solidify at room temperature. Pour it down the drain, it will harden, clinging to the pipe. Oil clings to the wall of the drain pipe, clogging the drain for a long time and giving off an unpleasant odor.
6. Expired medicine
Expired medications should be packed and disposed of according to protocol. You should not pour it down the drain. Compounds in expired drugs are likely to have an adverse effect on the environment. Especially in places where there is no wastewater treatment system, if you pour it down the drain, these compounds will seep into the water, affecting the water source.
7. Bleach
Pouring bleach down the drain can form dangerous chloramine gas. The fumes from this gas are irritating to the body, leading to a host of more serious health problems.
