Despite the old wives’ tale that coffee grounds down the garbage disposal is good for the plumbing and eliminating odors, we at Green’s Plumbing are here to tell you the truth:
Nothing causes more blockages and clogged pipes than coffee grounds and grease. Even if you don’t put them down the drain at the same time, they’ll meet up and form a sludgy impenetrable nightmare.
Do you have a garden or access to one? All plant life can benefit from the used coffee grounds; you don’t have to compost. Just spread them around in your garden to repel insects like ants and slugs and stimulate your plants. If you don’t have a garden, start compiling them in a container and give them to someone who does. If you have houseplants, you can put both coffee grounds and spent tea in them.
