Why should you not pour grease down the sink?


Excess grease after cooking is often dumped instead of reused, but if you pour it into your plumbing, the consequences can be worrisome.

Home Serve, a British home advice site, says the most visible consequence of this is all the grease that builds up over time in the pipes which can cause blockages. It is estimated that fat and oil buildup causes about 47% of sanitary sewer overflows that occur each year in the United States.

Unlike water or other liquids, grease doesn’t completely escape the pipes and into the sewage system. After they cool and reach ambient temperature, they solidify, adhere to pipes and accumulate, thickening over time, becoming obstructions to flow.

How to properly handle excess cooking grease

In case of cold weather, grease solidifies into blocks, you can easily shovel them in the trash. If grease is in liquid form, you can pour it into an empty bottle and collect until the bottle is full and then put the bottle in the trash.

If the amount of excess oil and fat is not too large, you can wait for the oil to cool, then blot the oil with paper towels and discard. This method in addition to effective oil collection also cleans pots, pans, dishes, making washing easier.

In case you have spilled grease down the sink, you still have a solution to deal with them, the most effective is using vinegar and baking soda. The chemical reaction created by these two substances breaks down any solidified grease and does not damage the pipeline.

In addition, you should correct errors immediately after pouring grease down the drain, to avoid them having time to accumulate and cause blockages. You can pour a few cups of hot water down the sink drain, then pour in the baking soda and vinegar mixture. Wait a while for this mixture to work, you pour one more time hot water down the drain pipe. Hot water will prevent the grease from returning to a solid state.

According to S&D Plumbing, you should also avoid corrosive chemical products that wear down your pipes.
