Kitchen Sink Leaking Underneath, From Top, Around Edges
Wet spots beneath your sink? A big or small leak under the kitchen sink is more than a nuisance. Even just listening to the sounds of dripping water might get you up.
It will be a horrible experience if the constant drip seeps through and drenches the cabinets, walls, and floors. If you don’t fix your leaky sink right away, it might cause water damage to your entire kitchen.
Why Do Kitchen Sinks Leak?
Several things can cause your sink to leak underneath, from the top, or around the edges.
Here’s a helpful list of possible causes of sink leaks. It’s critical to keep track of these causes before taking any steps to address the issue.
-
Worn Gaskets Or Washers
If your sink leaks from the top, it could be because of worn gaskets or washers. Usually, when these components wear out, your sink will leak when water is turned on.
However, some leaks can go under the countertop and drip beneath the sink. So, be sure to scrutinize under the basin for possible leakage.
To fix this issue, you’ll need to replace the washer or gasket. This fix is peculiar for those with a compression faucet.
-
Corroded Valve
Sinks are designed with valves to connect the spout and the faucet for the compression mechanism. The valves regulate the flow of water and stop leaks in the pipes.
Leaks and water pooling result from valve corroding or starting to fail.
Valves often corrode when excess water is present at the valve seat. To prevent leaks, the valves in your sink need to be cleaned regularly. A specialist can help avoid this issue before it gets worse.
-
Faulty or Damaged O-Ring
Do you notice any leaking around the edges of the handle?
If yes, it could be a faulty or damaged O-ring. The O-ring is a small disk that is attached to the stem screw to hold the faucet handle firmly.
After using the sink for an extended period, the O-ring may wear out or become loose, causing the sink to start leaking around the handle.
-
Problem with Water Supply Lines
Why do sinks leak underneath? Problematic water lines can cause your kitchen sink to leak underneath.
Sinks are usually designed with two water supply lines—a hot and a cold water line. However, you can get those with three water supply connections if you use a sprayer.
These water supply lines are vulnerable to leaks if their connections become loose or corroded.
Although a failed gasket can also cause leakage underneath, to fix this issue, you should consider replacing the gasket or tightening the connection of water lines.
-
Clogged P-Trap
Are you familiar with P-trap? It’s the section of pipe that curves and is located beneath a sink. It stops sewer gas from escaping through your plumbing and returning to your kitchen.
But debris, food fragments, and other impurities can reach the P-trap. These particles can obstruct proper water drainage, which could lead to a leak.
If your P-trap is also broken or corrupted, it can cause the sink to overflow. To prevent this event, you must clear all elements that can block the P-trap.
When it is broken or corrupted, consider replacing it.
-
Overaged Drain Putty
Usually, drains are sealed with putty to prevent leaks. If the putty is thin or starts to dry out, your sink may begin to leak. If the sink or drain is old, a leak can also develop.
To resolve this problem, consider calling a plumber to replace the drain putty properly.
-
High water pressure
Excessive water pressure is another factor that can cause sink leaks. The ideal water pressure in most homes is 40–60 PSI. When the water is high, it can be too hard on pipelines.
Extreme or incorrect water pressure may cause occasional leaks in the spring. In other cases, the pipes may burst into your plumbing. When it reaches this point, water will flow around the sink.
Below is how to repair a leak under the kitchen sink.
How to Fix a Leak Under Kitchen Sink
Having seen what causes sink leaks, it’s critical to learn about the solutions.
This will assist you in resolving any faucet-related issues and prevent such an incident. Nevertheless, a leaking sink can be fixed in multiple ways.
The faucet, spray hose, and sink strainer most frequently require repairs. The sink drain pipe or the hot and cold water supply lines may also need to be repaired.
Before you tackle the issue, be sure you have everything you need. These include an adjustable wrench, silicone caulk, plumber’s putty, basin wrench, and screwdriver.
With these tools, you may begin repairing anything.
Tightening the connection between the sink strainer and basket will stop leaks around the filter in your sink. If that still doesn’t work, clear up the old plumber’s putty, remove the filter, and stop the leak.
Replace it with a new one, and attach the filter again. If it continues, you should get a new sink strainer.
To address the seeping sink near the drain pipe, you can tighten the pipe slip nuts, beginning with the one closest to the sink. If the issue continues, use silicone tape or epoxy to seal the area around the sliding nuts.
If the pipe has leaks, rubber gaskets may need to be replaced. To access the gasket, loosen the first slip nut. Make sure your towels and bucket are nearby as you work on that.
Finding Leaks Around the Sink
Before we wrap up our talk, we would like to teach you how to locate leaks under, above, or around the borders of your sink. Gaining this expertise can help you identify any issues with your faucet.
Get a flashlight and spend a few minutes looking inside the cabinet. If you see any leakage or if it appears to be from a previous incident, your faucet may be faulty.
If you also see a puddle, look right above it, examining every item as you move vertically.
Additionally, check the area around the sink’s edges. If water is not visible, gradually strengthen the pipes and contacts beneath the sink.
After touching each item, check your fingertips to see if the water is still there. Turn on the faucet and recheck everything if you can’t find the water source.
Taking care of a leaking kitchen sink can be tricky, particularly if you need to figure out what’s causing it. The details will help locate the cause of the leak.
Cleaning the mare won’t fix the problem. To halt the leak, you must fix or replace the issue. It’s advisable to let experts handle it if you are unable to do it yourself.
