How to Fix a Clogged Drain From Coffee Grounds

The electric garbage disposal has made getting rid of kitchen scraps very easy. Unfortunately, garbage disposals and plumbing pipes are not designed to handle some discards, such as coffee grounds, that people routinely dump down the drain. The fine consistency of coffee grounds makes it easy for them to stick to any debris already in the pipes. This can create an obstruction or enlarge an existing one. Fortunately, clearing a drain that is clogged with coffee grounds is not difficult.

Save money by clearing a clogged drain yourself.

Use a Plunger

Step 1

Fill the sink with enough water that the rubber cup of the plunger is fully submerged.

Step 2

Seal the drain on the other side of a double sink by placing a rubber drain stop or a small towel in the drain opening.

Step 3

Hold the handle of the plunger with both hands and place the rubber cup directly on top of the drain opening. Push down and pull up on the plunger approximately 10 to15 times until the drain starts to clear.

Clearing the P-trap

Look under the sink and locate a U-shaped pipe If plunging the drain does not dislodge the coffee grounds. This pipe is commonly referred to as a P-trap. Position a bucket underneath the P-trap.

Step 2

Loosen the connections on both ends of the P-trap. If it is a metal pipe, use a pipe wrench to turn the connecting nuts counter-clockwise until it starts to loosen. If it is a plastic pipe, loosen the connections by turning it with your hand in a counter-clockwise direction.

Step 3

Remove the P-trap by pulling it away from the pipes that it is attached to. Be sure to position your bucket so that the contents from the pipes will fall into the bucket.

Step 4

Remove the obstruction in the P-trap using a gloved hand or a pointed tool such as a screwdriver. Rinse the P-trap with water until no obstructions remain. Look into the other connecting pipes (from the sink and to the wall) to ensure that there are no blockages.

Step 5

Reattach the P-trap. Tighten both connections by turning them clockwise. Once the trap is in place, turn on the faucet to ensure that the blockage has been completely removed.
