A leak in your sink is the most annoying yet the most embarrassing thing that could happen to your kitchen. These leaks are capable of doing a lot more damage than you could ever imagine. It is important to determine the source of the leak and repair it before a lot of harm is done to the furniture, to you through injury or even to your wallet. Get on top of the problem before it gets on-top of you!
The first thing you should do before anything else is to assess the leak and find the source. It is easy to identify a leak, narrowing it to the wet cabinet, a pool of water under the sink or a wet floor. A leak may also be coming from a pressurized point such as a hose supplying water to the sink. This will be noticeable by a spray of water or other liquid. Other leaks are hard to determine. For example, a faulty seal may require you to fill the sink so that you may actually see if there is an issue. There are other leaks that you will not notice until you have used the sink, so if you start to come across anything that stands out you may have discovered a new issue.
After assessing the leak, you can then go ahead and apply the appropriate measures to fix it. For water supply leaks, it is easy to notice the points from which they are leaking. This will be identifiable from the sprays and active leaks seen from the pressure points. Such situations are caused by shut-off valves that are not tight enough. It is here where, you can use a pipe wrench to tighten the valve and stop the leak. For those leaks that cannot be reached by the pipe wrench – for example behind the sinks – you can use adjustable or locking pliers to fasten them.
For the leaks that are caused by loose connections from the P-traps, blockage in the drainage pipes or corrosion of the metal traps, you can use another approach. If you tighten all the compression nuts and the leaking persists, you can consider removing the trap and cleaning it. In case there is a blockage that is causing the leaks, you can clear the drains using an auger. Afterwards, you can tighten the P-traps with compression nuts by hand or use pliers. Supposing you try to turn the nuts to compress them, and they are too tight, that means that they are corroded. At this point, you should consider replacing the trap with a new one.
In other situations, determining the source of the leaks is a huge hassle. Getting to know the exact point from which the pipes are clogged might be difficult. In such event, the probable cause would be the sink. The sink drain begins to leak only when the sink is full of water. The water usually flows back to the faucet or the sink drain and drips from below the sink. You will notice that the floor under your sink is wet or has a pool of water. Fixing this is fairly easy. You need to unscrew the blocked drain and attach it back using plumber’s putty or sometime of mold/clay. This will ensure that it is tightly sealed.
In the event that you are not able to identify the source of a leak or you are unable to repair it on your own, it is better to seek the services of a professional such as a blocked drain plumber or any other expert. You may try to fix the leak and end up causing more damage than good. For this reason, it is best to call a plumber to check the issue and advise you on whether to replace a couple of materials, or fix the leak on the spot.
