A plumber says this.....

I had a girlfriend tell me that dumping coffee grounds down the sink was good for it.  I've been doing it for 3 years and all's the better .....

Some of my house plants Thrive on coffee. My flowering cactus adores coffee in the spring. I use it in my gardens and like I said, some like it and respond well. But none take it hot, right out the pot so if it’s weeds, scalding hot coffee, tea or water gets them headed in the right direction. I have no facts on sewer rats and coffee or the bacterial lifeforms and coffee. So drink up and lets see if the EPA is concerned enough to grant some money for a study.Thank you curious person.

I was going to post something similar. Coffee grounds are great for gardens.

The used grounds. Put them around the base of your bushes, lilacs, and in your flower bed.

I have heard that it is good to dump coffee grounds down the drain every now and then.

I've heard of doing that, but you're not supposed to dump anything down the drain, except thin liquids.Or, you'll clog up the drain. Now, if you're talking about a garbage disposal, you can dump coffee grounds down there, but not dandelions like my sister-in -law did, and not corn husks, like my freind's freind did. Garbage disposals take a lot of abuse. When we first moved into an apartment, the maintainence man found that someone had put little pieces of concrete and paint chips down the disposal. What's wrong with the garbage can.?  Toilets take  alot of abuse too. People think they are wood chippers, or garbage disposals.

They are said to deter slugs so sprinkle them around plants like hostas which slugs and snails love. Otherwise put them on the compost heap.

From one of several thousand resources on the subject:

1). If you do, a little at a time with plenty of water.

2). Wasting of water would be the concern here if you conserve it, or are paying for water usage (being out in the "country" I have a well, so this doesn't affect me, but the coffee grounds would affect my septic).

I know people who get used coffee grounds by the 5 gal. bucket from Dunkin Donuts for their gardens and compost bins.  If you ask them they will save them for you to pick up on a regular basis, but you must follow through and take them.  Earthworms love them, and in turn their castings benefit your soil and plants. 

I don’t know if coffee is safe. 

I do know to not put rice down the disposal.

I wouldnt advise it, you will get blocked drains somewhere along the line!!
