How To Fix A Slow-Draining Vessel Sink


A vessel sink sits on top of the vanity, and it is removable, which makes repair easy. However, like other plumbing fixtures, they can develop leaks. Vessel sinks may come with or without an overflow (the part that prevents water spilling from the basin), and they could have a grid drain, a twist stopper or a pop-up stopper. It is possible to troubleshoot and fix a slow vessel sink drain by following these tips.

Prepare to Work

For this project, you need:

  • paper towels or old rag
  • screwdriver
  • nails
  • adjustable pliers
  • baking soda
  • bucket
  • copper wire
  • baking soda
  • white distilled vinegar

Open the grid drain or pop-up stopper by pushing down on the stopper-rod (metal rod). If it has a twist drain, pull the raised knob up. Rotate the drain stopper to remove it, and set it aside. 

Flush the Drain

A drain clog could be the cause of slow draining. Look inside the drain for hair, soap scum, and other debris. Clean the stopper and drain with old rags or paper towels, then reinstall the stopper.

Remove items from under the sink, and fill the basin with hot water, and detach the drain stopper. The hot water should dissolve grease and other debris in the pipes. 

To fix clogs on the mouth of the drain, pour baking soda over the mouth, Pour in white vinegar until you see bubbles, then add hot water. The bubbling should help clear the drain.

Clear the P-Trap

If the sink still won't drain, the P-trap could be clogged. The P-trap is the curved piping under the sink, which is commonly plastic. Spread a towel under the sink, then set the bucket under the P-trap to catch water. Use the pliers to detach the nut on the drain line that connects to the wall.

Disconnect the end of the trap, and let the water release into the bucket, and dump it in the tub. Insert a copper wire to remove debris that may be stuck in the P-trap.

Detach the ring-nut on the upper end of the P-trap, and move the trap down to release water. Insert a copper wire into the drain opening to clear debris. 

Reconnect the P-trap, and tighten the connection. Pour water down the drain, and observe the P-trap for clogging or leaks. If it leaks, tighten the nuts in small increments, and repeat the test until the leak stops.

A sink that keeps leaking or clogging could mean an obstruction could be in the vent, or drain pipes may need cleaning. Contact a plumber  under these circumstances.

building a pool-side bathhouse

I installed a pool about three years ago, and my family has loved having it. My only issue with having a pool in the backyard was the fact that the kids would run through the house soaking wet to go to the bathroom. I decided that it was time for me to invest in a bathhouse by the pool. My husband and I planned to do much of the work ourselves, but needed to hire a plumber to run all of the plumbing from the house to the bathhouse. To find a step-by-step tutorial about building a bathhouse from the ground up, read through our blog.
