A Simple Solution for Fixing a Leaky Kitchen Sink Drain
By Mark J. Donovan
||Recently I discovered a puddle of water underneath my kitchen sink. Upon closer inspection I noticed that there was an intermittent leak coming from the kitchen sink drain assembly where the P-trap connected into the bottom of the kitchen sink.
What was perplexing was that there was no apparent leak when I just ran the faucet and let the water drain out the kitchen sink. It turned out that the leak only manifested itself when the sink was first filled with water, and then the drain plug was pulled out of the sink drain.
It was while the large volume of water poured through the drain that I observed water seeping around the large plastic nut that connected the P-trap assembly to the kitchen sink drain itself.
With the source of the leak discovered I removed the P-trap by simply unscrewing the large plastic nut that connected the P-trap to the kitchen sink drain. The P-trap nut can be unscrewed with your hand. No tools were required.
Upon close inspection of the P-trap I noticed that the plastic washer that sat inside the P-trap was deformed and quite dirty.
My first attempt to solve the leak was to clean the P-trap and the plastic washer and then reattach the assembly back to the base of the kitchen sink drain. Unfortunately the leak persisted.
