Keeping your home in tip-top shape means constant work. You probably take pride in making sure that every area of your home is in excellent condition. But when was the last time you checked the parts of the property that are out of sight, like the plumbing and the drainage system? Chances are, you don’t really think about your plumbing until something goes wrong and the damage is already done. 

One of the biggest issues that could potentially affect your plumbing system is a blocked drain. A clog in your drain is not something you can ignore as it can have a detrimental effect on the home’s plumbing system and your family’s health, too. Additionally, it can impact your home’s structural integrity to the extent that the house could be inhabitable. 

In this post, our team of licensed plumbing experts explains some of the most harmful effects of having blocked drains at home, but first, let’s take a closer look at the common causes of drain blockages:

Common Causes of Clogged Drains

Tree Roots

Roots of trees within the property are among the most common causes of clogs in the water and sewer mains. Older homes are more prone to this problem, but even newer systems can get affected by this, too.

Tree roots are constantly looking for moisture and are naturally drawn to the water in your sewer pipes. If there’s a crack or leak, it can find its way in. If there are trees on your property or you live in a wooded area, you should be aware of this problem and have a video inspection performed at least every few years or so.   

Flushable Wipes 

Many people make the mistake of flushing their wipes down the toilet, thinking that it’s safe to do so because they’re supposed to be “flushable.” Here’s the truth about it: no matter how thick or thin they are, whether they’re called wipes, paper towels, facial tissue, or any other name, they should never be flushed down the toilet. 

Feminine Hygiene Products

Feminine hygiene products and diapers are a danger to pipes because they have cotton and other fibers that are non-biodegradable and therefore have the capacity not only to block pipes but also attract other clogging elements. 

Oil, Grease, and Food

Oil and grease from food are one of the worst enemies of your plumbing system. Many homeowners do not realize the damage they're causing when they allow oily substances to go down their drains. These oils can accumulate and cause clogs. 

Food scraps should also never go down the sink, or even the laundry drains, nor should they be flushed down the toilet. Drains don’t tolerate food, mainly because they can be sticky or sharp, which is never good in a pipe. 

What Are the Effects of Clogged Drains?

Now that you know the common culprits behind blocked drains, it’s time to understand how they could affect your home and the health of your family:

Risks to Your Health

Clogged drains can lead to bacterial growth in your pipes that could cause certain allergies and diseases. When there’s a blockage in the drains, water cannot flow properly, and there could be a backflow that could reach your sinks and then become stagnant. The water that flows back already contains bacteria, and as you use the sink, you and your family are put at risk of contamination and infections of bacteria and viruses. These can even diffuse in the air around the home, which is never a good thing, especially for family members with allergies. 

Unpleasant Odour

When there are clogged drains in your system, water can accumulate in the pipes and stay there until it begins to emit an unpleasant odor. It may be tolerable at first, but it could come to a point where you’ll feel your home is inhabitable because of how horrible the smell is. 

Pests and Mold

What do pests and mold have in common? They both thrive in dark and moist areas. That means if there are any clogs in your plumbing system, there is stagnant water somewhere that could be a breeding ground for pests. Mosquitoes, for one, love stagnant water. Mold and mildew also grow rapidly in moist areas, and because clogged drains mean the house is damp in many areas because of water backflow, it’s likely your home has mold problems, too. 

Slow Drainage

This is one of the first signs that you see that tell you you’re dealing with clogged drains. It is one of the most annoying ones, too. Imagine when you’re rushing in the morning, and you can’t use the sink or the tub because they’re not draining fast enough. What’s worse is when there’s the backflow of water that could smell horrible and expose you to bacteria and viruses. 


When drainage blocks are not addressed immediately, they could cause leaks when the pipes succumb to extreme water pressure and burst. The lines could also weaken and get worn and torn due to the stagnant water.

If some part of your lawn looks greener or there are patches of grass taller than the rest, it could indicate leaking pipes that may be due to clogged drains. 

Weakened Home Structure

Clogged drains can compromise the entire plumbing system, and their effects can be more extensive than you’ve expected. Water may no longer flow where it’s supposed to. It could stay stagnant in certain areas, while some might find its way through cracks in the pipe and into the house’s structure or foundation. When not fixed immediately, it could end up as structural damage that would be costly to repair. 


A blocked drain can lead to all the issues mentioned above, and the repair work required could be pretty expensive. It is therefore important that you do what you can to prevent clogs. Something as simple as educating the members of the family about what they’re only allowed into the sink, toilet, tub, and pipes and what they should never flush.
