Causes of Basement Flooding

Whether your basement floods due to heavy rains or a broken hot water tank, it's important to know the cause of the flooding so you can prevent it in the future.

1. Heavy rains

First, heavy rain can cause your gutters to overflow, which can then leak into your basement through the foundation walls. This is especially common if you have a flat roof and are not able to properly clean out the gutters after a storm; the more debris that gets caught in the gutter, the more likely it is to overflow during heavy rains.

Second, heavy rain can increase the rate at which water drains from your roof into your yard. If this happens, it will also drain into your basement through cracks or other holes in the foundation. You may be able to prevent this by installing a proper roof drainage system and keeping trees and shrubs away from your home's perimeter so that they don't block runoff channels.

Third, heavy rain can cause soil erosion around your foundation walls. This can create cracks through which water can flow into your basement and cause flooding issues even when there isn't any leakage from above ground sources like gutters or roofs!

2. Clogged drains

Clogged drains are a common cause of basement flooding. The drain can become clogged with hair, food debris, or other materials that are flushed down the toilet without being properly disposed of. In such cases, water can back up and flood your basement floor. If you have a sump pump installed in your home's drainage system, it may be able to keep up with the flow of water coming into it through the drain—but if your sump pump fails to work properly and quickly enough because it is too small or old (or both), then flooding will occur anyway because there will be nowhere else for all that extra water to go!

What can I do? Check all your drains regularly so that they don't get clogged up; this will help prevent them from becoming blocked by hair or other debris which could lead to an emergency situation. 

3. Broken hot water tank

A broken hot water tank can cause a lot of damage to your basement. Many hot water tanks are located in the basement and are a common cause of flooding when they break or leak. If you have an old, rusty tank, this is a possibility to consider.

Hot water tanks aren't always located in the basement and can be placed anywhere in the house but if there's any chance that yours is near your foundation and could leak or break, it's best to replace it with a new one immediately.

4. Frozen pipes

Frozen pipes can also be the cause of your flooding. The best way to prevent frozen pipes is by making sure that the temperature in your home remains above freezing, if possible. If you have a basement that is unfinished or otherwise not heated, make sure your heat is turned on and working properly. Check that there are no cracks or openings where warm air could escape from your house's walls or floor. You should insulate any exposed pipes with foam insulation tape during winter months to keep them warm and reduce their likelihood of freezing over (especially overnight).

5. Sewer system backup

If you have a sewer backup, it means that the sewer line is clogged and backed up water is coming into your home through the drains. This can cause a lot of damage to your home, so it's important to take care of this problem quickly! The first thing you should do is call a plumber who knows about these issues and can help unclog your pipes. He or she will most likely need to remove the entire drainpipe from under your sink, so plan on being without running water for at least one day while they fix it. 

The best way to prevent basement flooding is to check your sump pump and drainage system and make sure it’s in working order. If you have clear gutters, the rainwater will flow away from your house rather than pooling at the foundation. You should also watch for clogs in drains and pipes so that water doesn’t overflow onto floors or into walls. Finally, be prepared for freezing temperatures by insulating pipes with bubble wrap or wrapping them with towels soaked in warm water before bedtime each night.
