Problems Caused by Your Slow Draining Sink

If your sink is draining slowly, it can cause a lot of problems. Not only will it be a pain to have to wait for the water to drain, but it can also lead to some serious issues.

Mold And Mildew

If water stands in your sink for too long, it can create the perfect environment for mold and mildew to grow. This can cause some serious health problems, so it’s important to take care of the problem as soon as you can.


Stains can form on your sink and countertop if water doesn’t drain properly. These can be tough to get rid of, so it’s best to take care of the problem as quickly as possible. When they sit in the sink for too long, food particles and soap scum can leave rings on your sink.


Having a slow-draining sink can be frustrating. You’ll spend more time waiting for the water to go down than you would if it was draining properly. This can be a real inconvenience, especially when you’re in a hurry. You also do not like the sight in the sink after you’re done brushing your teeth, hand-washing the dishes, or shaving.


If your sink doesn’t drain properly, it can also cause smells to build up. The smell may be from mold and mildew, food particles, or soap scum. This can be really unpleasant and make it tough to want to use your sink.


Slow bathroom and kitchen sinks can result in soap scum buildup in the drain. While this is normal, the problem gets worse when the liquid is not able to drain away as quickly as it should. The combination of soap and dirty water will cake on the side of the pipe and be a magnet for further dirt, grime and grease.

Sewer Line Issues

Slow drains are often a sign of a bigger problem, especially when you have multiple slow drains in your home. Clogs in your sink can be a sign of issues with your sewer line. That’s why it’s important to call a professional to take care of the problem.

Causes And Remedies of Slow Draining Sinks

There are a few things that can cause your sink to drain slowly. It could be a clog, a blockage in the pipes, or something else. It usually takes a professional plumber to diagnose the problem. Here are a few of the most common causes and remedies:

Tree Roots

If your sink is draining slowly, it might be because of tree roots. Tree roots can grow into the sewer line and cause a blockage. If this is the case, you’ll need to call a professional for help.

Minor Clogs

The most common reason for a slow-draining sink is a clog. This can be caused by food particles, hair, or grease. If it’s a minor clog, you might be able to clear it up yourself. Try using a plunger or a sink snake to dislodge the clog. However, you may need a plumber to determine if the clog is the main cause of the problem.

Septic Tank Sludge

A slow draining sink could be because of septic tank sludge. This is a build-up of solid waste that can block the pipes. If this is the case, you’ll need to have your septic tank cleaned by a professional.

Drain Pipes Are Clogged

There are pipes in your home responsible for draining the water out. If one of these pipes is clogged, it can cause your sink to drain slowly. This can be caused by a build-up of food particles, hair, or grease. If this is the case, you’ll need to call a professional plumber to clear the blockage.

Vent Pipes Are Blocked

Your home has a system of vents that allow air to flow in and out. If one of these pipes is blocked, it can cause your sink to drain slowly. This can be caused by a build-up of bird or rodent droppings, autumn leaves, or winter snow. If this is the cause, you’ll need to call an expert to clear the vent pipes.


A slow draining sink may occur because the pipes or other plumbing elements have deteriorated. This may be as a result of age, rust, or corrosion. You’ll need to call a professional plumber to replace the affected pipes and accessories.

P-Trap Issues

The P-trap is a curved pipe that’s installed under your sink. It helps to catch debris and prevents sewer gasses from entering your home. If this pipe is not installed properly, it can cause your sink to drain slowly. You might need to call a plumber to adjust the P-trap or replace it altogether. Another problem with the P-trap can be a clog. Clogs can settle in the bend as a result of grease washed down the drain which makes other items stick to the pipe. A P-trap clean by a plumber often eliminates the clog.

Old Plumbing

If your sink is draining slowly, it might be because the plumbing in your home is old and outdated. If so, you’ll need to call a professional plumber to replace the affected pipes. Regular maintenance and inspections can help to prevent this from happening. Schedule at least a yearly maintenance with a licensed plumbing contractor for best results.

Lodged Objects

Finally, small objects can get trapped in the drainage pipe. This could be a piece of food, jewelry, a hairball, or even a toy. When this happens, you’ll need to remove the object yourself or call a plumber to do it for you.

What Are The Benefits of Correcting Slow-Draining Sinks?

When you correct a slow draining sink, it drains faster. While that may be obvious, there are other benefits to be gained by having a sink that drains quickly:

System Improves

When all the drains in your home are draining properly, it can help to improve the overall function of your drainage system. This replaces the frustration that comes with a slow-draining sink with peace of mind.

No Mold, No Mildew

One of the main benefits of having a properly draining sink is that you don’t have to worry about mold and mildew. These can form when water pools and doesn’t drain properly. When a plumber comes over for a cleaning, he often helps clear mold and mildew. If the problem persists after a slow draining sink episode, clean and clear the area with a bleach and water solution.

Clean Pipes Mean a Healthy Home

Another benefit of correcting a slow-draining sink is that you’re keeping your home clean. When water pools and doesn’t drain properly, it can be a breeding ground for bacteria and other harmful organisms. This is not only dangerous for your family but also for your pets. A plumber often resolves the problem by cleaning out sediments in your pipes. No sediments mean no clogs for a long while and a clean, healthy home.
