Is it better for the pipes to pour grease down the toilet rather than the kitchen sink? (NSFW)

NO!

Both will clog when the grease conceals which is pretty much when the grease hits the water

Neither. Grease should go in a can or jar, tied up in multiple plastic bags, and outside in the trash.

Put it in a jar and put it in the trash.

Any human waste goes down the toilet, via defacation.
Kitchen grease goes in the trash, no animal products in compost.

I keep old peanut jars for just this purpose. When they are filled, I trash them.
Please don’t pour down the drains or toilets.

@chyna Yes! I use coffee cans with lids.

No. Here’s another reason:
Anti clog products will damage the wax/grease ring sealing your toilet from the floor.

This is wrong:. Grease comes naturally from going number 2.

Your Red Jasper turds are not the same as a cup of bacon grease or the grease from your favorite standing rib roast. Any “grease” coming through your digestive tract is full of a lot of other stuff, including a lot of bacteria.

If your body is producing enough bile and you are not eating fat burgers three meals a day, this is not a concern. If you are having symptoms of steatorrhea, then go see a doctor and quit eating shitty food.

@zenvelo Someone had to say it. Haha!

Yes, if you flush while pouring. But it’s bad news for your drains and sewers. Don’t do it.

No! You need hot water to poor grease down the drain so it doesn’t harden and clog your pipes or save up jars that you get from the store and put your grease in there and through it in the trash.

Fat poured down the toilet solidifies and blocks the drainage system. Look up “fatberg” in Google.

During cool weather my grease and oils go in the wood burning stove where I effectively convert them into heat. In the summer they go in the fire pit and become fire starters for camp fires.
S’mores anyone?

^I bet your fires smell wonderful!

@LuckyGuy that is a great way to start a fire.

Hot water poured down the toilet could melt the wax seal between toilet and floor. Don’t do it!

@chyna Bacon grease is the best! Smear it on newspaper, discarded mail, yard waste stick or twigs and it burns great!
Actually my wood burning stove in the house does not release any odors inside. And once it comes up to the temperature sufficient to light off the reburner there is no smoke or odor outside either. That usually takes about 5 minutes.

And it is all free!

@kritiper That is an excellent point. Good safety tip!

Put the grease in the refrigerator and when it hardens scrape it into the garbage.

Pouring grease down the drain causes “F O G” – - Fat Oil and Grease clogs in the sewer pipes !
