How To Fix Kitchen Sink Leak

If you are here, it probably means that your kitchen sink is leaking.

We all know how much of a hassle leaks can be. Not only do they make our kitchens look bad, but they can also lead to expensive repairs or replacements.

There are many reasons why a kitchen sink leak happens. It could be that the drain pipe isn’t properly connected and water has pooled around it, or maybe you have an old pipe with corrosion and sediment buildup. Whatever the cause may be, once you identify your problem there is a solution for it! This article will go through some steps on how to fix kitchen sink leak?

So without any further ado, let’s get straight into the 5 steps on how to fix a leaky kitchen sink!

First Step – Check Underneath The Sink For Leaks

First things first, you should check for leaks under the sink by running water through the faucet and looking underneath for signs of wetness. This method works best if there has been an ongoing issue with leakage in your kitchen. Look near baseboards or walls for obvious signs of dampness or puddles.

An added method would be to use a screwdriver and lightly tap on your kitchen sink. This will help detect if there are any loose pipes that are creating noise or leaks underneath the surface of your kitchen sink.

Second Step – Turn Off The Water And Fix Leaks

If the leak is due to an ongoing issue, chances are, you have already turned off the water supply so now it’s time to fix the leaks! Check under your kitchen sink for connections between hoses and valves. You may need a wrench in order to remove compression nuts on hoses before being able to pull them away from each other. Once these hoses have been, inspect them for cracks or holes. If you find any leaks, you will need to replace the damaged hose!       

If there are no loose connections under your kitchen sink, you can use a screwdriver and lightly tap against the metal pipe that is at the centre of your kitchen sink. This process may cause some water to leak out but this is an easy way to locate where exactly the leak is coming from.

If neither of these two options work for you, then unfortunately, your only option is to tear apart parts of your kitchen in order to find the source of leakage.

Third Step – Replace Washers And Repair Leaks

All washers in both the hot and cold supply lines must be replaced with new ones if they are old or damaged. You can go to a hardware store in order to find the correct type of washer that you need for your kitchen sink supply lines. If there is a leak in between two connectors, wrap Teflon plumber’s tape clockwise around each end and connect them together again.

Fourth Step – Check The Drain And P-Trap For Leaks

If your waste disposer is leaking from below the sink, turn off the water supply and clean away any debris from the drain pipe which may be causing blockages. You will also need to make sure that the p-trap beneath your kitchen sink is free of rust or other obstructions which would cause leaks.

Fifth Step – Replace Your Kitchen Sink P-Trap If Needed

Turn on the water supply and test your kitchen sink one more time to make sure that all leaks have been fixed. If you find that you still have a leak, it’s time to replace your p-trap! That’s it! 

Last Step – Turn On The Water Supply And Test

This will solve most typical cases of leaky kitchen sinks. I hope this short article has helped to guide you through how to fix a leaky kitchen sink step by step! Good luck!
